Description
Description
Measure low sulfur dioxide concentrations in ambient air with the MH2000-SO2 Low Range detector. Choose a 0-1 ppm or 0-5 ppm version, both with 0.001 ppm resolution. This High Precision, single-gas SO2 configuration uses an electrochemical sensor and an internal sampling pump.
Two Ambient Measuring Spans
The 0-1 ppm option has a lower maximum measuring span, while the 0-5 ppm option covers a broader low-concentration interval. Match the ordered span to the concentration expected in the sample and the measurement procedure. Each order supplies one instrument configured for the selected version; it does not automatically cover both ranges.
Resolution describes the stated reading increment. The 0.001 ppm value does not establish a detection limit or numerical measurement accuracy. This ambient-air configuration serves low-concentration SO2 tasks. Select the separate flue-gas-specific or biogas-specific configuration when the application requires one of those sensor arrangements.
Display and Alarm Setup
The LCD dot-matrix display shows gas type, concentration, unit, battery level and time. English and Chinese operating interfaces are available. Concentration can be displayed in μmol/mol, ppm or mg/m³, with 1 μmol/mol equivalent to 1 ppm.
Two alarm stages allow the setpoints to be adjusted. Sound, light and vibration provide the outputs, including an 85 dB sound alarm and blue/red alarm lights. Self-check, zero calibration, factory reset, and temperature and pressure compensation are provided. Operate the controls according to the supplied instructions for the selected Low Range SO2 version.

Sampling and Recording Options
The internal pump provides up to 1 L/min flow and ten adjustment settings. The 300 g instrument uses a rechargeable lithium-polymer battery. Filters, drying accessories and sampling probes are separate choices for the intended sampling arrangement.
Data logging and PC export are optional and excluded from this base configuration. Gallery images illustrate the common housing and controls. The case view does not represent two supplied instruments, and a connected cable does not indicate included PC export.
