SRS Smart Room Sensor

Descriptions

SRS is wall mounted unit of an air type transmitter that is used indoor. It provides a stable, repeatable, reliable and accurate means of measuring both temperature and humidity in the room. The polymer capacitance sensor used in the SRS is not affected by any condensation, high humidity or contaminants present in the measure environment.

Built with miniaturized electronics the SRS sensor is inter-changeable thereforerequiring no recalibration at all. A completely plug and play solution for quick and easy installation that minimizes installation & maintenance costs. Its sophisticated integrated circuits design provides a fully humidity and temperature compensated 4-20mA-output signal. The SRS enclosure is made of ABS plastic.
