14 best humidity monitors

Humidity monitors, also known as humidity meters or hygrometers, are devices used to measure and display the relative humidity levels in the air. These instruments are commonly used in various applications, including monitoring indoor air quality, maintaining ideal conditions for sensitive equipment, and ensuring comfortable environments.

Here are some key aspects related to humidity monitors:

  1. Measurement of Relative Humidity: Humidity monitors are designed to measure and display the relative humidity (RH) in the surrounding air.Relative humidity is expressed as a percentage and indicates how much moisture the air holds compared to the maximum it can hold at a given temperature.

  2. Accuracy and Precision: High-quality humidity monitors are known for their accuracy and precision in measuring humidity levels. They provide reliable data for various applications, including those where precise control of humidity is crucial.

  3. Digital Displays: Most modern humidity monitors feature digital displays that show the current relative humidity reading. This makes it easy for users to quickly assess the humidity conditions in a room or environment.

  4. Indoor Air Quality: Humidity monitors are commonly used in homes, offices, and commercial buildings to monitor indoor air quality. Maintaining the right humidity levels can help prevent issues such as mold growth, dry skin, and respiratory problems.

  5. HVAC Systems: In heating, ventilation, and air conditioning (HVAC) systems, humidity monitors can be integrated to control and adjust humidity levels, ensuring that the environment remains comfortable and healthy.

  6. Sensitive Equipment: Humidity monitors are used in settings where precise humidity control is essential, such as laboratories, museums, and data centers. They help protect sensitive equipment and artifacts from damage due to extreme humidity fluctuations.

  7. Greenhouses: Humidity monitors are employed in greenhouse environments to maintain optimal conditions for plant growth. Monitoring and controlling humidity levels can significantly impact crop health and yield.

  8. Dew Point Calculation: Some advanced humidity monitors can calculate the dew point, which is the temperature at which air becomes saturated and moisture begins to condense. This information is valuable in various industrial processes and HVAC applications.

  9. Portable and Stationary Models: Humidity monitors come in both portable and stationary models. Portable units are handy for spot-checking humidity levels in different areas, while stationary units are typically installed in a fixed location for continuous monitoring.

  10. Calibration: To ensure accuracy, some humidity monitors may require periodic calibration or adjustment. This is particularly important in applications where precise humidity measurements are critical.

  11. Integration with Smart Home Systems: Some humidity monitors can be integrated with smart home automation systems, allowing users to remotely monitor and control humidity levels via smartphone apps or voice commands.

In summary, humidity monitors are essential tools for measuring and monitoring relative humidity levels in various environments. They play a crucial role in maintaining comfortable and healthy living conditions, preserving sensitive equipment and materials, and optimizing industrial processes.

User questions & answers

Question: Can i reset the comfort range? 79 degrees f is much too high to be comfortable imo
Answer: Actually the temp does have a bearing on the comfort indicator as amorina states. It will need to be a minimum of 20 degrees and between 50 and 70% humidity to indicate as comfortable. I agree with you that this is a little high and perhaps 18 would be ok. Other sources state that 40% humidity is ideal so who knows!I think just go with what feels right. In answer to your question though unfortunately the comfort range can not be reset or altered.
Question: is this made in usa
Answer: In China. I bought 3 of them, but don't find them useful. The setting for humid, dry, comfort is inaccurate for a relativity level reading in a home environment. At least in the Midwest region. They say 49% is dry when in fact it's too much for a home to carry, at least in the winter colder temps.
Question: Has anyone had this long enough to know if the battery will last at least one year
Answer: This is probably too late to be of use to the original poster, but maybe it will help someone. I purchased mine in March of '17 and the unit just died on me this past weekend, I was still using the original battery. I changed the battery and the thermometer was still dead, but that's less than $10 for nearly 2 years of service on a single battery.
Question: Any way to calibrate temperature
Answer: Calibrate means that you adjust your measuring tool (e.g. thermometer, hygrometer, speedometer, etc.) to give a known value when it's measuring (detecting) that value; you usually do this by adjusting a screw or other mechanism that results in the unit showing a 'reading', or measurement, of that known value on its display or output. This unit does NOT have any calibration adjustment.

User questions & answers

Question: Does this device record the temperature changes throughout the day 2 days or 3 days that you can review later
Answer: The first part of your question is yes, it records the current temperature. The answer to the second part is no, it only gives the current temperature of the location it is placed; i.e., bedroom, den, bathroom, outside etc. It also gives the humidity.
Question: Could this be used in an egg incubator to give a more accurate reading than the built in thermometer-hydrometer
Answer: This little device is very accurate we use it in our bath rooms because we are trying to get humidity down so we can install our flooring
Question: Does this hygrometer need calibration? It is reading 15 degrees low
Answer: Just got mine and the humidity reads 7-10% low. I did the salt water calibration test twice and it never got over 65%. The hygrometer is useless.
Question: Does this have a calibration feature? I want to be able to periodically recalibrate
Answer: No, it does not. I find it to be quite accurate, though! I would imagine that you could just remove the battery and re-insert it to recalibrate. But manually, no calibration feature. I have baseboard heat with no thermostat so this really helps me know room temperature and humidity. Good product!

User questions & answers

Question: Does the HIGH/LOW reset automatically? I need one that doesn't reset until I reset it
Answer: It uses three 12 hour time blocks (36 total hours) per the 7/19/16 response and automatically resets. This screws up being able to determine the 24 hour hi-lo I was used to with another model. I much prefer the one that auto resets every 24 hours from battery insertion. On the latter, by inserting the batteries at midnight, a daily hi-lo was always available. With the 36 hour look-back this daily Hi-Lo feature is totally useless IMO.
Question: does the unit have a backlight? Thanks
Answer: ASSUMING THEY HAS BACK LIGHT -I BOUGHT 3, A FLASHLIGHT IN A NECESSITY AT NIGHT, AND THEY MAKE CUTE PAPER WEIGHTS!!!!!
Question: I'd like to know if it also makes the measurement in degree celsius
Answer: No it doesn't :( celsius x 9/5 + 32
Question: accuracy
Answer: You might want to check out my review of this product (written 11/17/15). I bought 3 of these, compared them to each other for accuracy in temp and humidity and gave detailed results. Overall summary is, 2 of the units were pretty good with both humidity & temp accuracy (most likely acceptable for most people's use), the 3rd monitor was not. It's a crap shoot as far as getting one that's in the satisfactory range of accuracy for both readings, I think.

User questions & answers

Question: Does it need aa or aaa battery
Answer: Yes, it use 2 AAA batteries.
Question: How accurate is this unit
Answer: Very accurate same sensor used in Davis VP2 Pro stations. Temperature +/- (.36F) full scale, +/- (2%) humidity. Most SHT31's won't hit 100% humidity but neither will $800 Vaisala and why the NWS ASOS stations jumps to 100% when sensor reaches 98%.
Question: Temperature is only in Fahrenheit unit or the unit can be changed to Celsius
Answer: Both Fahrenheit and Celsius. This pro device responds faster to surrounding humidity level compared to the regular device and more accurate.
Question: Can it be calibrated
Answer: Not only can it be calibrated, it should be calibrated. Google the "salt test" for Hygromters. The salt test provides a reliable and reproducible 75% relative humidity to test the accuracy of your hygrometer. Mine was 14% off, but spot on after calibration with the salt test.

Answer: Well, I know I've seen "dry" when it's reading under 47%. As for "wet", I can't say at what point it triggered. Only that a steamy bathroom after a shower got the "wet" environment alert at well over 70%.
Question: What are the measurements of the hygrometer in inches
Answer: The display shows the temperature and humidity level in the area you have the hygrometer. There are no inches displayed, you may be reading the size of the hygrometer.
Question: Is this waterproof
Answer: no it clearly states it is NOT in the item description, Im guessing the seller prob updated since you asked so not sure why they didnt also answer your question
Question: How do you calibrate the humidity
Answer: It should come calibrated. Do you mean how to calibrate what values it says are dry, comfortable, or wet? I'm not sure you can do that.
