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 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.

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.

Question:	I want to use it to monitor humidity in a cheese cave at about 85%. Will it measure humidity this high
Answer:	Yes it will. The humidity range is 10%-99%.

The gauge designed with convenient kickstand and hanger built into the back, it works well on tables or walls and is hidden nicely in any small space and doesn't take up a lot of space in an office, bedroom,living room, kitchen, cigar, etc.

Require No Battery Monitor

The mechanical physical sensor requires no battery, and its working principle is to indicate the current temperature and humidity by pulling the pointer through the expansion and contraction of the metal sheet while they are changing.

Temperature / Moisture Reading

The transparent acrylic surface makes the gauge a sharp-looking of ℃/℉ readings and scales, monitoring the current temperature & humidity. And the housing of this monitor made of ABS material, which is durable but not easy to aging.

Sensitive to Weather Changes

Temperature and humidity sensing via the airflow circulation hole position, three sets of sensing holes on the back ensure to accelerate airflow and sense air temperature/humidity quickly, very sensitive to changes of the environment.

User questions & answers

Question:	Does it have any kind of electronic output to notifying you when a preset value has been reached
Answer:	No, this doesn't have Bluetooth or WiFi capabilities to send to a phone app or computer app. However, it is a fairly accurate little hygrometer and thermometer though, and I use it inside of my stringed instrument cases. I just set a reminder on my phone to remember to check it weekly and to attend to the humidification systems I put in with the stringed instruments.
