|---|---|
| Weight | 370 g (13.1 oz.) |
| Operating temperature | -20°C to +50°C (-4°F to +122°F) |
| O₂ humidity range | 0% to 99% relative humidity (non‑condensing) |
| Detection range – O₂ | 0–30.0% vol. (0.1% vol. increments) |
| Detection range – CO | 0–999 ppm (1 ppm increments) |
| Battery operating time (toxic, O₂, LEL sensors) | 20 hours |
BW recommends calibrating the detector at least once every 180 days (6 months).
Approved batteries are M5IR‑BAT0501 and M5IR‑BAT0502, as well as standard alkaline and NiMH rechargeable cells listed in the guide.
The battery provides up to 20 hours of operation with toxic, O₂ and LEL sensors.
A high alarm produces a constant beep, fast flash, L and target gas bar flash, and activates the vibrator alarm.
