Therma-Hygrometer with Internal & External Temperature Probe
Therma-Hygrometer with internal and external temperature probe
- New improved case design
- Displays both humidity and temperature
- Maximum, minimum memory function
- Integral sensor & remote probe
- Wall or stand mounting
The 810-140 Therma-Hygrometer simultaneously displays both the humidity and temperature in addition to indicating and recording the maximum and minimum readings.
Using the external remote probe with integrated three metre lead the unit measures both temperature and humidity over the range of -20 to 70 °C and 10 to 99 %RH. Alternatively using the internal sensor the unit measures temperature over the range of 0 to 50 °C.
This therma-hygrometer is ideal for monitoring both temperature and humidity in rooms, offices, factories and similar to ensure optimum working conditions are maintained.
The unit is housed in an ABS case, measuring 20 x 100 x 110 mm, that incorporates a useful foldaway stand and a keyhole slot for hanging on a wall.

It arrived well packed. Regarding temperature accuracy, when compared to my digital central heating thermostat which has an accuracy of ± 0.5°C, it normally indicates up to 0.5 °C less which is quite acceptable. Regarding Relative humidity I have no means of checking calibration but it gave me the 45 - 50% range I was expecting. It is however, fairly slow to react to changes of temperature but I do not see that as a problem, especially when considering it's low cost. To sum up, a desirable piece of kit.

Great length of cable, allows placement of the probe where needed. Easy to use and read off results. Just what I was looking for.

Very good accuracy, external Th&Rh probe with a long lead and fantastic price. Way better than amazon/ebay offerings and way cheaper than RS/Farnell offerings.
