Key Features

CO2 0–10,000 ppm (±1.5 % of range; typically ±10 ppm at 500 ppm after user calibration)
Optional O2 0–100 %
Optional dual temperature probes 0–50 °C or humidity sensor 0–100 % RH
Preset audible and visual alarms
Optional 1 m probe (Stowseek)
Data storage (1000 reading sets + 270 events) and USB download

Overview

The Geotech G150 is a CO2 analyser designed for indoor air quality applications. It measures CO2 0–10,000 ppm with options for O2, dual temperature probes, humidity, preset alarms and a 1 m Stowseek probe for illegal immigrant detection.

Working Principle

CO2 is measured by a custom dual-wavelength infrared cell with reference channel; optional O2 by an internal electrochemical cell. An internal pump (100 cc/min) draws the sample, with built-in gas moisture removal.

Applications

Benefits

Quick verification of CO2 levels for site audits
Data logging for long-term application
Built-in gas moisture removal
