Mengshen Temperature Multi Function Thermometer Hygrometer Review

If you need a similar product, this is a good choice. It works as it should and gives the impression of a quality instrument. When tested with my mechanical humidity and temperature gauges (of known high accuracy) this gauge was accurate on temperature readings and within 1% on humidity readings (very acceptable performance). The only caveat is that you must wait at least a minute for the moisture reading to stabilize before you get the most accurate reading. I can't comment on the accuracy of…

I almost returned this unit defective but found later that if you give it enough time to install (10-20 minutes) it is accurate. probe attachment problem. Due to the relatively large mass of the metal, it has a large thermal time constant and the metal itself must equilibrate with the ambient temperature before the sensor can equilibrate. The sensor is mounted on the end of a metal extension and I bet. that if the probe were made of some sort of plastic composite, the settling time would be…

Humidity is not very accurate and you cannot change the calibration constant. To be honest it has quite a large tolerance, the measurement takes more than a few seconds as the system needs to settle down. I use it within its capabilities, especially to check temperatures. The humidity is reduced by approx. 3% and increases depending on the value. I usually measure humidity around 45-65% with controls at 80%. I thought I would update the readings after 1 year of use. All measurements are slow…

Incredibly accurate humidity sensor for about 1/3 the price. I have owed it a little over 2 months now and am very happy with it. I did a salt test (depending on many different factors, it's best to wait 24-36 hours to keep 100%. Last thing to do is remove the sensor too early while the humidity nor "at a super snail" speed" " is increased) and this sensor showed a final value of 74.50%. To get faster and more accurate temperature readings, I wrapped the metal pin in "self-adhesive bandage"…

In some circumstances ventilation can make a house drier than air conditioning, it is also faster and much more energy efficient. On a warm day, ventilation can dry out a home that is too cool to turn on the air conditioning. Comparing indoor and outdoor dew points will tell you when ventilation is helpful. That's why I bought a dew point meter in 2014. Night airing in summer can be disastrous as relative humidity increases as the home cools. Wood, paper and some fabrics absorb moisture and…
