Product Overview

The HM-100B from HM Instruments uses nondispersive infrared absorption to measure carbon monoxide in air. A built-in sampling pump supplies the gas to the measurement path, while the touchscreen displays concentration and operating information.

Key Features

A 7-inch capacitive touchscreen and Android interface support measurement control and data review.
Digital flow sensing provides sampling-flow information during measurement.
Nitrogen and catalytic zeroing, with internal path switching, support zero adjustment.
A thermal printer, USB export and storage for more than 100000 records support test documentation.
Audible and visual alarms indicate configured operating conditions.

Applications

Use for air measurements in environmental protection and monitoring, public-place hygiene, occupational hygiene, disease-control work and research. Select the gas channel and range for the expected concentration, and match sampling temperature and humidity to the specified operating conditions.

Operation and Support

Warm up the instrument for the stated five-minute period, establish zero using the selected zeroing procedure and set the sampling flow within the specified range. Keep the sample within the gas-channel temperature limits. Store, export or print readings under the monitoring procedure; optional 4G communication requires the corresponding module.
