Room Humidity & Temperature Transmitters – HRTT-Series

Description

The HRTT-Series Room Humidity & Temperature Transmitters are designed to measure and monitor the relative humidity and temperature of air in various indoor environments. These transmitters convert measurements into standard signals of 0-10 Vdc or 4-20 mA and are available with or without an LCD display.

With options for ABS plastic or vandalism-secure stainless steel enclosures, the HRTT series ensures durability and versatility for use in residential, commercial, and public settings. The units are equipped with a long-term stable digital sensor for precise and reliable readings.
