The bright, large LCD shows real-time gas concentrations and the instrument's status at all times. The full function self-test verifies sensor, circuitry and battery integrity and activates the audible/visual alarms each time you turn the instrument on. The detector clearly advises the gas hazard present-Low, High, TWA and STEL gas alarm. Recorded TWA, STEL and Peak exposures can be displayed on demand. Designed with the most advanced RFI protection available today. Its IP 66/67 rating means its waterproof to 3ft (fully submerged) and the GasAlert Extreme also features a shock resistance concussion-proof boot. Delivered ready for use, simply clip the instrument to your pocket, belt or hard hat for unequalled protection. |
