Intended Use
The CM-100 is a portable measuring device for ascertaining the carbon dioxide concentration (CO_2) in the surrounding air using the exact and long-term stable NDIR measurement method (Non-Dispersive-Infrared-Absorption measurement). In addition the air temperature can be measured. Both measured values are shown in the display at the same time. The measurement interval is 2 minutes. This provides constantly current values. Threshold values can be individually adjusted by the user. An alarm is sounded when these threshold values are exceeded. The external sensor is compensated for altitude and temperature, so that the measured values are still exact at different altitudes and temperatures. The temperature compensation is carried out automatically, the operational altitude must be manually adjusted.
An RS-232 interface allows the further processing of the measuring data with an optional data cable.
The device is powered with 6 micro-batteries (type AAA, UM4). Operation with a power pack unit is also possible. Batteries and plug-in power pack are not included in delivery.
Measurements must not be carried out under unfavourable ambient conditions.
