COMMETER - Thermometer Hygrometer Barometer
Thermometers, hygrometers, barometers are designed for direct measurement of temperature, relative humidity, atmospheric pressure and atmospheric pressure tendency.
Advantages:
- included traceable calibration certificate
- dual line LCD display with special symbols
- 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
