New Low-range CO2 IAQ Analyser - Greater Accuracy, Connectivity & Options

The new Geotech G150G150 CO2 (0-10,000ppm) analyser has the accuracy essential for IAQ measurements very low CO2 concentrations in e.g., sick buildings (SBS). Newly designed and engineered, the G150 has options for O2, temperature, humidity and PC/Internet connection.

With a crystal clear screen with an excellent backlight the G150 is an ultra-modern replacement for the widely used Geotech CD98 analyser, launched in 1998. Geotech developed the G150 from 30 years experience and customer-focused research. That inspired making checking CO2 levels simple. Users just switch on the G150 and view the screen.

Low-range CO2 analyser demand
Reliance on accurate indoor air quality (IAQ) monitoring is greater than ever. Local authorities and consultants complete environmental site surveys on homes, offices and factories especially near potentially polluting sources like landfills. Port inspectors use carbon dioxide analysers with probes to discover 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.

At the heart of the new G150, designed and built by Geotech at its UK, Leamington Spa HQ, 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’s on-board electronics and microcontroller 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.

Supplied with a battery recharger, carry case and user manual on CD, G150 prices start at £875. Options include an O2 sensor (0-100%), a humidity sensor (0-100%), a temperature probe and 1m long hollow metal ’stowaway’ probe for commercial vehicle storage areas. PC USB connector and Analyser Data Manager Software is £215. More www.geotech.co.uk
