The Edgetech HT120 Series is a precision transmitter that provides quick and accurate humidity, barometric pressure,
temperature, absolute pressure and dew point measurements. Constructed of rugged 316 stainless steel, the HT120 series
is resistant to most chemicals and is ideally suited for many different applications such as environmental chambers,
compressed air, furnace and industrial applications.
The Edgetech HT120 Series has wide ranges and exceptional accuracy. Many psychometric units including wet bulb, ppmv,
gr/lbs, and dry bulb 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. Pre-calibrated field replaceable sensor tips are
available, interchangeability is ±1% and all units come with a NIST traceable calibration certificate.
The Edgetech HT120 can be used as a standalone smart humidity probe with one RS232 and three 0-10 VDC outputs or
can include a display option which includes a 2-line LCD backlit display as well as three 4-20Ma outputs, one RS232 and two
programmable relay contacts.
