AMT311 CO2 Controller with with Remote Sensor

Description:

1. The Wall Mount CO2 Controller AMT311, with built-in Dual Beam NDIR technology and Day/Night auto detect sensor, is specially designed to measures CO2 level for greenhouse and ventilation. The AMT311 also helps to extend your measure spot away from the display with 4.5 meters long cable connected to theremote sensor.

2. It is relay output could control the other connected devices, such as CO2 generator to produce in a greenhouse when the CO2 concentration is below to help increase plant yields by supplying CO2 required for photosynthesis.

3. It is perfect used in agricultural applications like greenhouse/hydroponics rooms, plant factories with both audible and visual alarms.

Features:

1. Dual Beam NDIR (Non-Dispersive-Infrared) technology is used to improve the long term stability.

2. CO2 controller; Tracer

3. Auto Detect Day/Night: The built-in Photo-Cell sensor can automatically detect whether it is Day or Night. It can override the CO2 control and shut off the CO2 generator by turning off the output power during the night. Conversely, if the Photo-Cell detects light and the CO2 level is low, the device will start the CO2 generator by turning on output power.

4. Chart with variable time Zoom Levels

5. Foolproof "Hold Home" function

6. Good Zone display indicate

7. Remote Sensor

8. Output Control: Output power is on when CO2 concentration is over Set Center+(1/2) Set zone, and off when CO2 concentration is below Set Center-(1/2) Set zone. For example, if the Set Center is 1200ppm, and the Set zone is 400ppm, the output power will shut off when CO2 over 1200+(1/2)*(400)=1400ppm, and power on when CO2 below 1200-(1/2)*(400)=1000ppm.
