To get a more accurate result, it’s recommended to calibrate the instrument with a gas that has CF close to 1. Reliable, rugged, and intrinsically safe, the ToxiRAE Pro PID can be easily attached to workers’ uniforms, and also provides a man-down alarm. For the most accurate measurements, an instrument should be calibrated using the gas under investigation. Inbuilt full RAE Systems 350 compounds correction factors list measure more chemicals than any other PID. In general, any compound with ionization energy (IE) lower than that of the lamp photons can be measured. The best way to calibrate a PID to different compounds is to use a standard of the gas of interest. If you decide to multiply the reading on the instrument rather than use the Library, the correction factor should be 32.26. Actual readings may vary with age and cleanliness of lamp, relative humidity, and other factors as well.

Although TN-106 shows a different correction factor, this is a guideline and the correction factor that is in the …
    • Correction Factor (CF) is a measure of the sensitivity of the LEL/PID sensor to a specific gas
    • CFs are scaling factors, they do not make a LEL/PID sensor specific to a chemical, they only correct the scale to that chemical. Accidental gas leaks pose a huge threat to properties, environment and human life. If the reading is 10ppm and the correction factor is 0.53, than the correct value of the gas is 5.3. Therefore, Honeywell manufactures a full and comprehensive range of gas detection products dedicated to all types of industrial facilities, from smaller boiler rooms to large petrochemical plants and oil refineries.

The MultiRAE Family and ToxiRAE Pro PID 10.6eV lamp use the same correction factors for the internal Library. However, Correction Factors (CFs) have been determined that enable the user to quantify a large number of chemicals using only a single calibration gas, typically isobutylene. Correction Factors and Ionisation Energies RAE Systems PIDs can be used for the detection of a wide variety of gases that exhibit different responses. Manually multiply the reading by the correction factor (CF) to obtain the concentration of the gas being measured. PIDs use ultraviolet (UV) rays to bombard gas samples and detect a broad range of VOCs such as formaldehyde, methane, and benzene, as well as hydrocarbons that typically occur in oil drilling and refining. RAE Systems MODEL MiniRae 3000 PRODUCT DESCRIPTION. Rugged housing withstands use in harsh environments .
