TRS-11a
The TRS-11a ambient temperature transducer with a display is designed for multipoint temperature measurement within the range of -40°C up to +85°C. It is particularly designed to measure temperature in rooms where food products are manufactured and stored. A display located on the front panel enables the reading of current temperature and autonomous operation of the module (without a computer system). It is equipped with Modbus RTU communication bus.
