precautions for the use of voc gas online detector
Precautions for the use of voc gas online detector: Charge the detector before first use. It is recommended to charge the detector after each working day. If the combustible gas sensor has been exposed to any catalyst pollutants/toxicants (e.g. sulphides, silica vapours, halogenated compounds, etc.), it is recommended that it should be tested with a known concentration of standard gas. The instrument should be calibrated prior to first use and thereafter, periodic calibrations should be performed based on use and exposure of the instrument to hazardous gases or contaminants. It is recommended that calibration must be performed every 180 days (6 months). It is recommended that the sensor be "shock tested" prior to daily use, i.e. to confirm that the detector is able to respond to the gas and activate the audible and visual alarms by exposing it to gases at concentrations above its high limit alarm point. The detector should be calibrated if it reads outside the specified range.
In some environments, interference from electromagnetic waves may cause the instrument to operate abnormally - Precautions for the use of the 4-in-1 gas detector! Avoid exposing the gas to cocoa gases should be avoided. Gas sensors are exposed to lead-containing compounds, silicone, chlorinated hydrocarbons. Although some organic vapours (e.g. leaded petrol, halogenated hydrocarbons) may temporarily stop the sensor from functioning correctly, in most cases calibration will restore its functionality. A sudden rise and then fall in gas detector readings or erratic readings may indicate that a gas concentration exceeds the upper range limit and may be dangerous.
voc online monitor analysis voc gas online monitor product features: configuration of high-performance FID / PID detector and reliable column system; large LCD display built-in WINDOWS operating system, to achieve the display of analytical spectra and data; wide measurement range, automatic range switching; automatic calibration function; EPC automatic flow control function, can be achieved by automatic control of the carrier gas and the sample flow rate Alarm function, automatic output instrument failure alarm and concentration alarm. Application scope: VOC online monitoring system on the specific use of the manufacturing industry for the emission of different gases, its monitoring project is not the same. Fixed pollution sources VOCs mainly from the spraying industry, leather industry, petrochemical plants, printing industry, sewage/waste treatment plants, petrol station leakage, biomass, coal combustion, semiconductor industry, metallurgical industry, etc., the main detection indicators for benzene, non-methane total hydrocarbons, and some of the volatile organic solvents.
