Description
Description
The MH2000-PH3 is an electrochemical phosphine gas detector with internal pump sampling. Select a Standard version from eight measuring spans, or a High Performance version in 0-2000 or 0-3000 ppm. The instrument measures PH3 concentration and presents the reading on an LCD dot-matrix display.
Choose the Performance and Measuring Span
Standard options are 0-5, 0-20, 0-50, 0-100, 0-500, 0-1000, 0-2000 and 0-3000 ppm. High Performance options are available only in 0-2000 and 0-3000 ppm. Choose both the performance grade and range when ordering; a higher upper measuring limit does not by itself identify a different performance grade.
The 2000 and 3000 ppm versions in either grade are single-gas configurations. This product measures phosphine only. Each ordered instrument has its selected span; the range menu does not represent interchangeable measuring ranges on one unit.
Sampling and Operator Controls
Ten suction levels provide pump adjustment, with flow up to 1 L/min. The interface supports English and Chinese. Concentration units can be switched between µmol/mol, ppm and mg/m³; 1 µmol/mol equals 1 ppm.
Two-stage sound and light alarms use adjustable setpoints, with vibration also available as an alarm output. Self-check, zero calibration and factory reset support setup. Temperature and pressure compensation are included as instrument functions. Use the supplied instructions for the selected PH3 configuration and measurement procedure.
