With more than 30 interchangeable and field-replaceable sensors, the WatchGas POLI portable multi-gas detector combines the best sensor technologies. It detects up to 6 gases simultaneously from a wide range of catalytic (explosive gas detection), infrared (hydrocarbons, methane, CO2, and N2O), electrochemical (including acetic acid, formaldehyde, methyl mercaptan), and photoionization lamp (PID) sensors for the detection of volatile organic compounds.
Its intuitive 2-button navigation, a large LCD with a "Flip" function (automatic screen reversal), and a measurement and event logger for later safety analysis make the WatchGas POLI a versatile and efficient portable gas detector for most tertiary or industrial applications.
