Online monitoring system EQMS-200

concentrationmeasurementfor gas

EQMS-200 VOCs Pollution Source Online Monitoring System adopts Photo Ionization Detection Method (PID) for gas detection. It uses ultraviolet light produced by ion lamp to irradiate the target gas and the target gas will be ionized after absorbing enough ultraviolet light. The concentration of the target gas can be detected by measuring the tiny current produced after gas ionization. Features IP65 protective design of high standard, can be installed indoors or outdoors Auto zeroing and auto calibration design, reduces work load of maintenance greatly Modular design, low maintenance cost Auto temperature and pressure compensation, accurately calculate gas concentration under normal pressure Battery module can be equipped for continuous monitoring when power out Applications Applied in various VOCs emission occasions including transportation equipment manufacturing, industrial coating, package printing, coating manufacturing, organic chemical industry, tire manufacturing, semiconductor integrated circuit industry, furniture manufacturing, electric wire, paint spraying & dry cleaning, shoemaking, synthetic material, etc. Specifications Measurement principle: PID Measuring gas: benzene, xylene, naphthalene, octane, ethylene, cyclohexane, acetone, propanal, ethers, etc. Range: 0~50ppm (customizable) Measuring error: ≤5%F.S. Response time: ＜5s (T90) Installation method: Wall-mounted or cabinet type Communication interface: RS232/RS485/GPRS Communication protocol: HJ/T 212, Modbus Output distance: The max wire transmission distance 2000m (RS485 mode) Working temperature: -25℃~55℃
