Description

Select the chlorine sensor configuration and measuring range for the sampling task. The MH2000-CL2 uses an internal pump and an electrochemical sensor to measure Cl2 concentration. Standard versions offer five separate ranges from 0-10 to 0-200 ppm; High Precision versions are available in 0-10, 0-50 and 0-100 ppm. Each order option is one portable, single-gas chlorine detector with its selected configuration and span.

Standard and High Precision Options

Sensor configuration	Available measuring ranges
Standard	0-10 / 20 / 50 / 100 / 200 ppm
High Precision	0-10 / 50 / 100 ppm

A Standard 0-10 ppm option and a High Precision 0-10 ppm option are different sensor configurations despite sharing the same measuring span. Choose the configuration and range together; the instrument supplied does not automatically cover every option on this page. The range describes the concentration interval of the selected version, rather than an interchangeable setting.

Internal Pump, Display and Alerts

Sampling flow reaches up to 1 L/min, with ten pump adjustment settings. An LCD dot-matrix display shows the gas type, concentration, unit, battery level and time. English and Chinese operating interfaces are available, with ppm and mg/m³ concentration displays.

Two alarm stages have adjustable setpoints, using sound, light and vibration outputs. The sound alarm is 85 dB; blue and red lights indicate low and high alarms. Temperature and pressure compensation, self-check, zero calibration and factory-reset controls support instrument setup. Operate the selected chlorine version according to its supplied instructions and the sampling procedure.

Recording and Sampling Package

Data logging and PC export are optional and are not included in this base configuration. Where stored readings are needed, ask about the recording configuration before ordering. Filters, drying accessories and high-temperature probes are separate sampling choices; their inclusion depends on the selected package.

The target gas is chlorine, Cl2. Select an instrument configured for the gas named in the measurement requirement; this page does not establish chlorine-dioxide or multi-gas measurement. Gallery images show the shared pump-detector housing. A connected cable does not indicate included PC export, and the carrying-case image does not represent a two-detector package.
