Description

M020-0025-000 MUNI MP425 Pre-Configured Four-Gas Detector, LEL/O2-LF/CO/H2S-Li-ion by mPower Electronics

The MUNI MP420 is a compact and lightweight 4-gas detector for worker safety at hazardous locations, with four standard sensors for oxygen (O₂), combustibles (LEL), carbon monoxide (CO) and hydrogen sulfide (H₂S). Alternative sensors are lead free oxygen (O₂), low power infrared methane (CH₄), sulfur dioxide (SO₂), and hydrogen cyanide (HCN). The detector is packaged in a robust housing with no moving parts. Its battery power offers 2 work shifts of run time for a standard 4-gas detector, and extended run time using a low-power infrared sensor. The simple, 2-button operation results in ultimate ease of use and significantly reduced time spent training the user.

Sensor Information

Sensor*	Resolution & Range	Response Time (t₉₀)
1. Combustibles (Pellistor) or (NDIR)†	1 - 100% LEL 1 - 100% LEL CH4	15 sec 30 sec
2. Oxygen (O₂) (Galvanic) or (Lead-free)	0.1 - 30.0% Vol 0.1 - 30.0% Vol	15 sec 15 sec
3. Hydrogen Sulfide (H₂S) or Hydrogen Cyanide (HCN)	0.1 - 100 ppm 0.1 - 50.0 ppm	15 sec 45 sec
4. Carbon Monoxide (CO) or Sulfur Dioxide (SO₂)	1 - 1000 ppm 0.1 - 20.0 ppm	15 sec 30 sec
* Sensors are replaceable but NOT interchangeable. Sensor configuration must be decided at time of purchase because each configuration has a unique circuit board. † NDIR CH₄ sensor detects methane and most hydrocarbons, but not some combustible gases such as hydrogen, acetylene and carbon disulfide. Contact mPower for assessment or approval for use in practical applications. † Pb-free (Lead-free) O₂ sensor has a longer life span than the galvanic version, but requires more battery power
