Edgetech Instruments HT120 Data sheet

The HT120 Series

barometric pressure, temperature, absolute pressure and dew point measurements in a wide range of applications. It has a wide temperature range of -40°C to 120°C and is resistant to most chemicals. This remote type transmitter comes standard with a 6 foot cable and is ideally suited for many different applications such as environmental chambers, compressed air, furnace and industrial applications. Many psychometric units are selectable through the main menu. The unit is calibrated and adjusted to a traceable reference standard and each unit comes with a NIST certificate of calibration.
