The HT120 is a precision transmitter that provides quick and accurate humidity, barometric pressure, temperature, absolute pressure and dew point measurements in a wide temperature range of applications. It has a wide temperature range of -40 to 120C and is resistance to most chemicals.
This remote type transmitter comes standard with a 6ft cable and is ideally suited for many different applications such as: environmental chambers, compressed air, furnace and industrial applications.
The unit is calibrated and adjusted to a traceable reference standard and
each unit comes with a NIST calibration certificate.
Many psychometric units are selectable through the main menu.

The sensor
The RHPT has a capacitive humidity sensor, which is insensitive to most of the contaminants found in process applications. The sensor is designed to tolerate gases such as ethanol, chlorine, ammonia, ETO, sodium chloride, ozone and hydrogen. The sensor can also withstand other harsh conditions such as thermal shock ( -40°C to +80°C ), high temperature combined with high humidity ( 95% rH ) and low humidity.
