Description
Description
This portable sulfur dioxide gas detector measures SO2 in surrounding air with an electrochemical sensor. The MH-1200H-S-SO2 uses diffusion sampling and comes in three measurement spans: 0-20, 0-50 and 0-100 ppm. Its rear clip keeps the instrument accessible during inspection rounds, while the protective cover surrounds the housing.
SO2 Readings and Range Selection
Choose the measurement span required for your SO2 monitoring procedure. Each range is a separate configuration of the same instrument. The 128 x 64 monochrome LCD displays gas information and concentration, with ppm and mg/m³ units available. Backlight timing can be adjusted, and the display illuminates automatically during an alarm.
Alarm Indication and On-Device Records
Sound, light and vibration provide three forms of alarm indication. The audible alarm is rated at 85 dB, and alarm set points can be configured for the monitoring procedure. The detector retains 100 alarm records for review on its screen, allowing the operator to look back at recorded alarm events without connecting to a computer. Zero and self-calibration functions, battery status checks and a factory reset function are available through the instrument controls.

Use and Configuration Notes
Follow the instrument instructions and the monitoring procedure for calibration, checks and alarm settings. Diffusion measurement requires exposure of the sensor inlet to the air being checked. The compact housing measures 131 x 83 x 35 mm and weighs approximately 240 g with its protective cover; power is supplied by a rechargeable 2300 mAh battery. Product photos illustrate the shared housing used in this series. Gas labels on the demonstration screen may differ from the selected SO2 configuration.
