1、Apply for temperature monitoring & controlling in duct (TTD2N), water and steam pipe(TTD4N), outside air(TTD3N), remote(TTD5N) and strap-on(TTD6N)

2、High performance digital temperature sensor and digital technology applied, ensure accurate measurement fast response and good long term stability

3、Multiple outputs selection, over voltage and reverse polarity protection, high reliability and anti-interference capability

4、Optional relay for alarm or ON/OFF control

5、Wide working temperature range and fast response

6、LCD & function keys can set parameters and calibrate output, so the product can become a stand alone controller

7、High protection rate up to IP65
