User questions & answers

Question:	What's the proper humidity for storing cigars in a humidor
Answer:	Yes it is. Calcium carbonate is the calcium form for this product. This is the same form many people take.
Question:	What is the process of calibrating this gauge
Answer:	As long as you have the correct lighting, d3 is not needed. Well once Or twice a month still, and only as part of their multivitamin. Get Arcadia lighting 6% or 12%, with d3 added. That’s right, you can buy lights that produce d3 just like the sun!
Question:	Can i use this for my cigars
Answer:	Contact the manufacturer-
Question:	battery included
Answer:	While I don't see it listed on the front of the package, I did purchase another brand from Animal essentials called seaweed calcium and that product does have NASC seal on it.

Question:	What size batteries does this take
Answer:	It takes 2 LR44 watch batteries. The batteries are included
Question:	Why does it cost an extra dollar for a temperature reading in freedom units
Answer:	Because a Freedom unit .... unit is a special order item and manufactured on demand. In effect it is a custom unit. Learn to use the traditional scales such as farenheit and centigrade.

Answer:	Yes. By pushing the yellow button as shown in the picture the reading will change from C to F
Question:	Has anyone used this for aquarium water temp check? Accurate
Answer:	It very accurately measures the temperature of the aquarium glass at the spot being measured which, under normal circumstances, should approximate the temperature of the rest of the aquarium contents.
Question:	Is it's good for pool temp
Answer:	Yes, that's why I bought mine, tired of the filter sucking up the floating thermometers. I find the first trigger reads 5 to 10 degrees high, next couple squeezes zeros in. If you hold the trigger in for a few seconds, it indicates it is calibrating and then gives the accurate temp first time. First option may be good for tricking your friends ...or not such good friends.
Question:	Does this accurately measure water temperature? I'm wondering if this will work to measure heated water being used for coffee making
Answer:	It did measure my coffee temp

User questions & answers

You can find the manual of this controller here: https://centurytimer.com/product_resources/BNQ-T7BH/Instruction-Manuals-for-Web-BNQ-T7BH.pdf

Answer:	Is this accurate with a heat lamp?
Question:	Is it normal for this to make an audible clicking noise when it turns on? Just got mine set up and it clicks when it turns on
Answer:	Is there anyway to disable that clicking sound? I just got mine today and its right next to my bed so its really irritating clicking on and off every 5 minutes.
Question:	can this be used for 2 che lamps
Answer:	With the wattage and amperage it says it can supply it should easily be able to handle 2 lamps. Just run a strip off the plug and only have them 2 lamps controlled by the thermostat. AGAIN, as long as it will handle what they say it can handle. A 100watt bulb should only pull just under 1 amp.

Answer:	Yes,included small button battery.
Question:	If I get the sensor wet while misting down my snake's tank will it damage the thermometer or make for an inaccurate reading

Question:	Is this compatible with a zoo med lighting hood
Answer:	Do not know...only calcium content is listed on label...which is calcium min 38%, calcium max 43%
Question:	Is it waterproof and how long is the cord to the sensor?, want to use it in a 600 gallon tank that is 2 ft. deep

User questions & answers

Question:	Does this have the attached magnet
Answer:	No, it's made to snap into a panel cutout. Also, I don't know really how much I'd rely on the numbers. I use it to gauge the temp in my office and mostly I compare the differences form day to day as opposed to knowing exactly what the temp is.
Question:	How do you change temp from C to F
Answer:	The sensor is already showing F° and as far as i see there are no buttons to change it
Question:	My hygrometer was already turned on when I unpacked it and it stopped work after 2 days. Would anyone know if I can fix this issue
Answer:	I don't think they're able to be turned off, mine also came turned on but works fine. I'd say return it, says it has free returns
Question:	Are you able to change the calibration on these
Answer:	I just looked and can't see any. This is a cheap unit. I don't think you can ask much of it.
Question:	C and F ???? or only F
Answer:	Only F. No C.
Question:	The top picture shows temperature only. The others show both humidity and temperature. Is there a switch between these displays
Answer:	I bought these and love them for monitoring humidity in my woodworking shop. The large (main) display is the humidity and the temperature is displayed (small digits) in the upper right-hand corner. There is no switch to switch humidity and temp to what the main (large digits) display is though. Hope this answers your question.
Question:	Are there batteries included
Answer:	Yes
Question:	Are these for wall mount? If so, probe seems to get inside the wall. What would be a typciall installation
Answer:	This is designed to be inserted into an opening (cut into anything) and sealed so that the internal conditions can be read from the outside, such as with a cloning propagation chamber.

User questions & answers

Question:	can you change the reading to Celsius
Answer:	No, why would you want to? Farenheit is much more accurate.
Question:	How long do the batteries last
Answer:	I've had some working for 18 months.
Question:	How do you calibrate humidity
Answer:	To the best of my knowledge, they cannot be calibrated. I've placed several in the sale location and have gotten only a few percentage points variance between the hygrometers.
