Description

The MH2000-NO pump detector measures nitric oxide concentration using an electrochemical sensor. Seven order options cover four Standard ranges and three High Performance ranges. Choose the performance grade and measuring range together for the NO measurement task. One instrument is supplied with the selected sensor configuration and span.

Select the Grade and Measuring Range

Configuration	Measuring ranges	Application limit
Standard	0-20 / 50 / 100 / 250 ppm	Routine NO concentration measurement
High Performance	0-500 / 1000 / 2000 ppm	Not suitable for flue-gas environments

The High Performance options on this page cannot be used in flue-gas environments. Select the separate flue-gas-specific NO configuration when that application is required. Each measuring span belongs to an individual order option; the supplied instrument does not automatically switch between all seven versions. The grade name identifies the sensor configuration and does not establish a numerical accuracy value.

Portable Sampling and Alarm Controls

The internal pump delivers up to 1 L/min with ten adjustment settings. An LCD dot-matrix display shows the gas type, concentration, unit, battery level and time. English and Chinese interfaces are available. Concentration units include μmol/mol, ppm and mg/m³, with 1 μmol/mol equivalent to 1 ppm.

Two alarm stages have adjustable setpoints. Sound, light and vibration provide the alarm outputs, including an 85 dB sound alarm and blue/red alarm lights. Temperature and pressure compensation, self-check, zero calibration and factory reset are provided for instrument setup. Use the controls according to the supplied instructions for the selected NO sensor.

Recording and Order Details

Data logging and USB export are optional and excluded from this base configuration. Ask about the recording option before ordering if stored measurements are needed. The rechargeable lithium-polymer battery takes 4-6 hours to charge, and the instrument weighs 300 g.

Gallery views illustrate the shared pump-detector housing. Screen readings are illustrative. The carrying-case photograph does not represent a two-instrument package, and a connected cable does not establish included PC export.
