Vaisala HUMICAP® Humidity and Temperature Transmitter Series HMT120 measures relative humidity (RH) and temperature (T) and outputs the measurements to analog current loop outputs. Other quantities, such as dewpoint (Td) can be calculated from the basic RH and T values according to the device configuration.

HMT120 is available either with a fixed probe directly attached to the transmitter housing, or with a remote probe with different (3/5/10/20m) cable lengths.

HMT120 can also be ordered with an optional LCD display without backlight.

HMT120 is typically installed mounted on the wall with up to four screws (not included). Rain and radiation shields and a duct installation kit are available as accessories. A drilling template is available at the end of this guide to help you position the screws correctly.
