Description

With three operating modes, this gas detector functions as multiple tools in one. Versatile and precise, the large LCD shows all gas readings, battery level, current time, and will automatically backlight in alarm conditions.

Features

Monitors ppm LEL, and % volume methane, O₂, CO and H₂S
0 to 100% volume methane option
Auto-ranging display of % LEL and % volume
Three operating modes: Normal, leak check, and bar hole
Leak check mode: PPM leak detector; adjustable display ranges; visual/audible pulses change with gas concentration; CO display in leak check mode, ideal for residential investigations
Bar hole test mode for underground leak checks
Status indicators: pump active, microprocessor status and battery level
Internal sample drawing pump with up to 50' range
Vibration, visual, and audible alarms
Automatic backlight during alarms
Bump test and calibration reminder with lock out option
Lithium ion or alkaline battery packs (interchangeable)
Alarm latching or non-latching
High impact, dust and water resistant design
Up to 600 hours of data logging with alarm trends
Snap-logging - on demand data recording
TWA and STEL readings with lunch-break mode
Intrinsically safe, ATEX/IECEx/CE

Applications

Personal monitoring
Confined spaces
Refineries/petrochemical
Chemical plants
Hazardous material
Water/wastewater
