1.Product description
SV-8124 fixed (with display) VOC gas detector, USES the us Baseline-MOCON import PID photoionization sensor, based on advanced PID (photoelectric from) technology, and it can detect various volatile gases (VOC) and ionization potential is less than or equal to 10.6 eV gas chroma value. Can detect the gas including: volatile organic compounds (VOCs), ammonia, benzene, toluene and benzene kind of derivatives, TDI, ethylene, alcohols, gasoline steam, jet fuel, liquid gas gas, butane acetaldehyde, part of the WMD, etc.
SV-8124 adopt Safe use of circuit design, have big screen LCD display , can be online at the scene to observe the target gas concentration ;can output RS485 digital signal ,communicating with console or PC ;4-20 mA current output of three –way system ,the signal directly proportional to the measured concentration of gas .With two level alarming output ,used high/low alarming environment , sound /light alarm ;With soft /hard two kinds of correction methods ,no need opening can be completed the calibration work .
2.Product feature
Show the concentration value of the scene 4-20 mA analog and RS-485 digital output signal.
Electronic sensor of explosion-proof shell, long life, low temperature resistance, anti-sulfide, silane gas poisoning.
The no contact way of Infrared Remote Control can complete zero and gain calibration.
Two special highlight flashing red LED lights, separately prompt high/low alarming, meanwhile the sound alarm send out the alarming voice, inform the staff at the first time, the two ways replay separately pulled, drive the other work of external control equipment.
Die –casting of stainless steel case for offshore platforms, and high temperature, humidity and other harsh environment.
Have a good seal, anti-corrosion and explosion –proof and anti-EMI, RFI function.
3.Product application :
Water treatment plant Oil well Refining and petrochemical plants
Steel mills, power plants, gas plants Coal Mine Chemical plants, raw material warehouse
