PH3 Wall Mounted Gas Detector
Brief Description:
The detector USES laser scattering method to detect dust concentration.The concentration value of the dust on LCD display suitable for factory application should be higher than the preset alarm point to immediately start the sound and light alarm signal or drive the exhaust system;International standard 4-20ma signal can be directly connected to the plant DCS system or PLC, and RS485 digital signal can be connected to the plant host computer.
The detector adopts embedded micro-control technology. simple operation, complete functions, high reliability.This product is suitable for indoor dust concentration monitoring place.
