- Sensor: Plug in, electrochemical cell (toxic and oxygen); Plug in, catalytic (LEL)
- User field options: Confidence beep, pass code protection, latching alarms, calibration due date,
bump due date, “SAFE” display function, language selection, span concentration values, combustible sensor measurement selection (0-100%LEL or 0-5.0% v/v methane), enable/disable automatic O2 calibration, STEL calculation period, disable backlight, battery type and stealth mode.
- Datalogging models only: clock, calendar and sampling rate
Alarm Indicators: Clearly advises alarm levels both visually and audibly
- Visual alarms: Two flashing alarm bars visible from all angles or LCD indicates gas present and alarm levels encountered
- Audible alarm: 95 dB variable pulsed audible alarm at 1 ft. / 30 cm (typical)
- Vibrator alarm: Pulses warning in gas alarm conditions, or for any status alarms
- Other: Low battery, over range, multiple gas and missing sensor
Alarm Levels: Instantaneous Low Alarm for all gases; instantaneous High Alarm for all gases; TWA (time weighted average) and STEL (short term exposure limit) for H2S, CO, SO2; OL (over limit alarm) for combustible gases
LCD: Continuous, alphanumeric gas readout and status display advises:
- Gases monitored: H2S, CO, O2, SO2, combustibles (0-100% LEL or 0-5.0% methane)
- Gas concentration: Simultaneous and continuously displays gas concentration(s) present
(in ppm, %LEL, or % v/v)
- TWA ppm or %: Records STEL and TWA exposures and displays on demand
- Peak ppm or %: Records and displays peak exposure to gas and displays on demand
- Alarm setpoints: Displayed on activation
