Description
Description
Check phosphine concentration in surrounding air with this portable phosphine gas detector. The MH-1200H-S-PH3 combines an electrochemical PH3 sensor with diffusion sampling, a rear clip and a protective cover. Four range configurations are available: 0-5, 0-20, 0-50 and 0-100 ppm.
Choose the PH3 Measurement Span
Select the span required by your monitoring procedure. Each option is a separate range configuration of the instrument, so the range is selected when ordering. The display resolution is 0.1 ppm. Diffusion sampling measures air at the sensor inlet; keep that inlet exposed to the air being checked and follow the instrument instructions for checks and calibration.
Concentration Display and Alarm Review
A 128 x 64 monochrome LCD shows the gas and its concentration, with ppm and mg/m³ display units available. Set the backlight timing through the controls; it also illuminates automatically when an alarm occurs. Sound, light and vibration provide alarm indications, with an 85 dB audible alarm and configurable alarm set points. The instrument stores 100 alarm records for review on its screen.

Instrument Controls and Carrying
Zero calibration, self-calibration, battery status checks and a factory reset function are available through the instrument controls. Use the specified calibration procedure and the alarm settings required for your monitoring task. A rechargeable 2300 mAh lithium-polymer battery powers the detector. Its housing measures 131 x 83 x 35 mm, and the instrument weighs approximately 240 g including its protective cover. The rear clip provides a carrying point during inspection rounds.
Product photos illustrate the housing shared across this series. Gas names on the demonstration screen may differ from the selected PH3 configuration.
