UNI 321 – Maintenance Free Single Gas Detectors

Overview

The UNI 321 is a disposable or maintenance-free version of UNI single gas detector. It detects hydrogen sulfide (H2S), carbon monoxide (CO) or oxygen (O2) in a selection of models with operating lives of 12 months (MP101), 24 months (MP102) or 36 months (MP103). The detectors have large LCDs providing maximum readability in the field. Six bright red LEDs allow for quick alarm notification. Constructed of strong and durable material, the UNI 321 is designed to be comfortable, yet drop-resistant. The UNI detectors can easily be bump tested and calibrated using the CaliCase System.
