mPower MUNI MP420
4 In 1 Compact Multi-Gas Detectors
OVERVIEW
The MUNI MP420 is a compact and lightweight 4-gas detector for
worker safety in hazardous locations with four standard sensors for
oxygen (O2), combustibles (LEL), carbon monoxide (CO), and hydrogen
sulfide (H2S). Alternative sensors include low power infrared
methane (CH4), sulfur dioxide (SO2) and hydrogen cyanide (HCN). The
detector is housed in a rugged enclosure with no moving parts. Its
battery power provides 24 hours of operation for a standard 4-gas
detector and extended run time when using a low power infrared
sensor. Simple 2-button operation provides ultimate ease of use and
significantly reduces user training time. To save users money,
sensors are not interchangeable and must be specified at the time
of purchase.
FEATURES
• Various models for basic confined space entry (CSE) compliance,
plus SO2 and HCN sensors.
• Diffusion sampling
• Compact, robust, lightweight & wearable
• Auto backlit LCD with large numeric digits
• Easy-to-navigate menu with two buttons
• Up to 4 replaceable sensors out of 8 choices;
non-interchangeability reduces monitor cost
• Battery operation 24 hours with pellistor LEL sensor or extended
time with low-power infrared LEL sensor
• Two-color status indicators on regular self-diagnosis of sensor,
battery and circuitry
• Wide angle LED alarms
• 1000 Events log
• Combination charge adapter / micro-USB PC interface cable
• IP-68 weather ingress rating
• Optional BLE wireless connectivity
• Optional MuniDock for convenient bump & calibration
• Durable double-shot outer case
