WebThe Tiger XTL portable VOC gas detector is a variant of the hugely popular Tiger XTL, but low on cost and high on performance. The portable VOC gas detector utilises revolutionary, patented photoionisation detection (PID) sensor technology with humidity resistance. The anti-contamination design provides market-leading accuracy and run-time for ... WebMA regulations determine the types and placement of smoke detectors in residential properties. The rules differ based on when a property was built or significantly improved. …

Web1.Permanent, highly precise residual oil measurement (oil vapor) with PID sensor (photo-ionic-detector). 2.Ideal for mobile measurement: The PID sensor is ready for measurement within about 30 minutes. 3. Long-term stable measuring results due to automatic zeropoint calibration. The integrated mini catalyst reliably generates a defined ... A photoionization detector or PID is a type of gas detector. Typical photoionization detectors measure volatile organic compounds and other gases in concentrations from sub parts per billion to 10 000 parts per million (ppm). The photoionization detector is an efficient and inexpensive detector for many gas … See more In a photoionization detector high-energy photons, typically in the vacuum ultraviolet (VUV) range, break molecules into positively charged ions. As compounds enter the detector they are bombarded by high-energy UV … See more The first commercial application of photoionization detection was in 1973 as a hand-held instrument for the purpose of detecting leaks of VOCs, specifically vinyl chloride monomer (VCM), at a chemical manufacturing facility. The photoionization … See more PID lamp photon emissions depend on the type of fill gas (which defines the light energy produced) and the lamp window, which affects the energy of photons that can exit the lamp: The 10.6 eV lamp is the most common because it has … See more With a gas chromatograph, filter tube, or other separation technique upstream of the PID, matrix effects are generally avoided because the analyte enters the detector isolated from interfering compounds. Response to stand … See more WebPhotodetection converts an optical signal into a signal of another form.
