UNI 321 Maintenance-Free Single Gas Detectors

Professional gas detection and alarm systems

          The UNI 321 is a disposable, maintenance-free version of the UNI single gas monitor. It detects H2S, CO or O2 in a selection of models with operating lives of 24 months (MP102) or 36 months (MP103)*. The detectors have a large LCD providing maximum readability in the field. The UNI 321 displays remaining battery run time, while the RT versions display real-time concentrations.  MP102RT runs 2 years but has a hibernation feature that allows up to 3 years. Six bright red LEDs allow for quick alarm notification. Constructed of strong and durable material, the UNI is designed to be comfortable, yet drop-resistant. The UNI detectors can easily be bump tested and calibrated with Single Docking Box or 4-Bay CaliCase System.

  *Storage life before turn-on is 6 months

NOTE: No concentration readings are displayed, but instead show the remaining operating time or alarm condition. If a concentration readout is needed, please see UMI MP100 Single Gas Detectors
