COMMETER
Thermometer Hygrometer Barometer

Thermometers, hygrometers, barometers are designed for measurement of temperature, relative humidity, dew-point, atmospheric pressure and atmospheric pressure tendency.
Advantages:

* included traceable calibration certificate
* dual line LCD display with special symbols
* dew-point reading
* barometric pressure tendency reading for last three hours
* adjustable dual alarm with audio indication for each channel
* memory of minimum and maximum values
* function Hold - manual storing of actual values for later displaying
