QB2000 CO2 controller for mushroom with 4-20mA and RS485 input
QB2000 composed of controller and detectors, can control different kind of sensors, simple to install and operate, microprocessor controlled, the controller can raise the alarming when the detected concentration reached the preset value. so it is widely used in oil,chemical,gas station etc.
Features:
♦ 128 x 64 dot matrix big screen liquid digital display
♦ different kinds of gas can be measured simultaneously
♦ two alarm levels of each channels can be set separately
♦ 8 channel 4-20mA/16 channel RS485 output signal
♦ Password verify is required when important operation
