Description
Description
The portable MH-1200H-S-NO2 measures nitrogen dioxide (NO2) in surrounding air during inspection rounds. Its electrochemical sensor uses diffusion sampling, while a rear clip and protective cover help keep the instrument accessible between readings. Select the NO2 measurement span that fits the concentration range required for your procedure.
Range and Sampling Choices
The available configurations cover 0-20, 0-50 and 0-100 ppm. Each is a separate range option for the same instrument model. In its standard diffusion setup, ambient air reaches the sensor opening directly.
Readings and Alarms
A 128 x 64 monochrome LCD shows the gas reading and supports ppm and mg/m³ display units. Backlight timing is adjustable, with automatic illumination during an alarm. Sound, light and vibration alerts draw attention to an alarm condition, and the sound alarm is rated at 85 dB. Set points can be configured for the monitoring procedure. The instrument retains 100 alarm records that can be reviewed on its display, and zero and self-calibration functions are available for routine setup.

Configuration Notes
This configuration measures NO2 specifically; an NO detector or combined NOx detector serves a different measurement request. Choose range and alarm settings according to the intended monitoring procedure, and use the supplied instructions for calibration and checking. For diffusion measurement, leave the sensor inlet exposed to the air being monitored. The product photos show the common housing of this series, and their demonstration screen may show other gases.
