(1) Using the latest patented technology sensitive element,has the characteristics of self-recovery and self-correction function, high accuracy, and good consistency.
(2) Big high brightness LCD display screen,intuitive observation,easy operation.
(3) Temperature unit selection:degree centigrade(℃),Fahrenheit degree(℉) can be setting,can be used on a global scale;
(4) The temperature, humidity error correction Settings,is convenient to check on a regular basis ;
(5) It can facilitate remote monitoring system integration,with RS485 interface,adopt stander MODBUS protocol.
(6) Special air duct design,Circuit temperature rise does not affect performance detection of the sensor.
(7) External ports have resistance to electromagnetic interference design,and high reliability.
(8) There is the defence function of the power input.There is no damage to equipment if the power input of plus or minus .
(9) Modular structure, installation, maintenance is convenient.
Attention Matters:
(1) The horizontal distance between air conditioning air supply outlet and sensor should be greater than 1.5 m,
and the distance to the ceiling air supply outlet should be greater than 0.5 m.
(2) Slot at port on PVC terminal head, or it is advisable to install the sensor groove profile online,in order to prevent segregation
under the floor cold air through the slot effect sensor test.
