Product Usage Instructions
Charging the Monitor
- Connect the AC adapter to the monitor.
- Allow the monitor to charge for approximately 4.5 hours until it reaches a full charge.
Calibration and Bump Test
- Use the calibration cup for manual calibration.
- Consider using the MuniDock single-bay or CaliCase 4-bay options for automated bump test and calibration.
Data Logging and Alarms
- Monitor up to 1000 events including alarms, function tests, and calibrations.
Sensor Information
- Note that sensors are replaceable but not interchangeable due to unique circuit boards for each configuration.
- Choose the sensor configuration at the time of purchase as each configuration serves a specific purpose.
Frequently Asked Questions (FAQ)
-
Q: Can I use the monitor for detecting all types of combustible gases?
A: The NDIR CH4 sensor can detect methane and most hydrocarbons but not all combustible gases like hydrogen, acetylene, and carbon disulfide. Contact mPower for assessment or approval for use in practical applications. -
Q: What is the difference between the O2 sensors?
A: The Pb-free (LF, Lead-free) O2 sensor has a longer lifespan than the galvanic version but requires more battery power.
MP42X Series
Compact & Lightweight 4-Gas Monitors
The MUNI MP42X 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 sulfur dioxide (SO2), low power infrared methane (CH4) for LEL, and lead-free oxygen (O2-LF). 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 up to 30 days 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.
