Description

Measure hydrogen chloride concentration with the MH2000-HCL electrochemical detector and its adjustable internal sampling pump. This portable HCl detector is available in Standard, High Precision and High Performance configurations, with the measuring span selected for the order.

HCl Configurations and Measuring Spans

Standard and High Precision versions each offer 0-10, 0-20, 0-50 and 0-100 ppm. They share the same available spans but are separate performance configurations. Select the performance grade as well as the range to identify the required version.

High Performance versions cover 0-500, 0-1000 or 0-2000 ppm and are single-gas instruments. All options on this page measure hydrogen chloride only. The menu describes eleven order combinations, with one selected configuration supplied per instrument.

Sampling Adjustment and Display

The internal pump provides ten suction levels and flow up to 1 L/min. An LCD dot-matrix display presents the gas type, concentration, unit, battery level and time. English and Chinese interfaces are available, and the concentration display can switch between µmol/mol, ppm and mg/m³.

Two-stage sound and light alarms have adjustable setpoints, with vibration also available as an alarm output. Self-check and zero calibration support instrument setup, alongside factory reset and temperature and pressure compensation functions. Follow the supplied instructions for the chosen HCl configuration when using these controls.

Recording and Package Choices

Optional recording stores more than 100,000 readings, with an adjustable interval of 5 to 3600 seconds. USB download and printing are optional data functions. Specify these requirements when ordering so the selected package matches the intended recordkeeping procedure.

The standard package contains the detector, carrying case, charging/data cable and instruction manual. The cable alone does not provide the optional recording function. Gallery images illustrate the shared pump-detector housing; screen readings are illustrative and the case view does not represent two supplied detectors.
