New CO2 Analyser is Fast, Easy to Use and Very Accurate

Reliance on accurate indoor air quality (IAQ) monitoring is greater than ever for environmental site surveys on homes, offices and factories especially near potentially polluting sources like landfills. Border control and port inspectors may use carbon dioxide analysers with probes to discover stowaways and illegal immigrants in lorries and containers. Food packers with modified air packaging (MAP) and growers with controlled environments in e.g., glasshouses or for mushroom farming all seek accurate, reliable gas analysis.

Geotech’s new G150 carbon dioxide (CO2) analyser has the accuracy essential for IAQ measurements in very low CO2 concentrations of 0-10,000ppm. This level of accuracy is vitally important when checking, for example, sick building syndrome. Newly designed and engineered, the G150 has options for oxygen (O2), temperature, humidity and PC/Internet hook up. Checking IAQ CO2 levels is simple. Users just switch on the G150 and view the crystal-clear screen.

With backlight on its easy-to-read screen, the Geotech G150 is a replacement the earlier Geotech CD98 analyser. Geotech has developed the G150 from 30-years of experience and customer-focused research.

At the heart of the new G150, designed and built by Geotech in the UK is a custom, Geotech-designed, CO2 analysis cell. Geotech’s new infrared absorption cell has increased length for low-levels CO2 to give maximum sensitivity and accuracy. The G150 is specifically designed for 0-10,000ppm, (0.0-1.0 %). This accuracy is essential as IAQ tests measure very small concentrations of CO2. In normal fresh air CO2 ranges between 380-420ppm (0.038-0.042%) while concerns with sick building syndrome (SBS) start with CO2 as low as 500ppm (0.05%).

Options include oxygen (O2) analysis using a factory-fitted electrochemical cell with a service replacement life of three years in air. An optional probe measures humidity and temperature. The probe, with a carry-case assists, environmental site surveyors as they move between locations. The G150-11N measures CO2, O2 humidity and temperature.

The on-board electronics and microcontroller in the G150 use the latest proven available technology which has increased data storage, ease-of-use, longer life and PC/Internet connectivity. The on-board rechargeable battery lasts for more than 12 hours. Moisture removal is built in which aids reading stability and accuracy.

Also new with the G150 is the option of a unique ID for each location against which the G150 stores a set of readings of date, time, CO2, O2, temperature and humidity. In total the G150 stores 1000 data sets. These can be screen-viewed or, via PC-USB cable, downloaded to Geotech’s optional Analyser Data Manager Software. With this, users can also download calibration events and an analyser’s set-up profiles to copy to another G150 readied for immediate use. PC connectivity also provides Internet access for remote, down-the-line diagnostics and firmware updates.
