New! Portable Nitrous Oxide Analysers for Patient & Occupational H&S from Geotech

Measuring N2O TWA-Exposure
The G200 in occupational health specification measures low-range background N2O in ppm. As a portable personal exposure monitor the G200 gives an 8-hour time weighted average (TWA) exposure for which the COSHH, EH40 limit is 100ppm. It can measure background N2O levels or operate in ‘rapid-response’ leak-detection mode. The G200 is designed to help prevent anaesthetists and others from prolonged exposure to low-range N2O and stay within occupational exposure limits.

Piped medical gas verification
In its piped-gas check specification, as the G210, the analyser measures concentration of N2O and optionally O2 at 0-100%. With N2O it measures CO2 at 0-2000ppm and with the O2 option, CO at 0-500ppm. This can help medical staff and consultants ensure piped medical gases are as specified and safe. The G210 also includes the option of a 16-character ID for unique site and piped gas sample point location against which it stores each reading.

New technology
These new Geotech G200 N2O analysers give users greater accuracy, precision and speed with all of the functions, options and connectivity expected of the latest equipment. Newly designed and engineered, the G200 analysers are the ultra-modern replacements for two previous Geotech models and are based on Geotech’s experience and customer-focused research. At the heart of the new G200, designed and built by Geotech at its UK, Leamington Spa HQ, is a custom Geotech-designed infrared absorption N2O analysis cell. This cell is greatly improved and gives maximum sensitivity and accuracy with very low-range N2O.

The onboard electronics and microcontroller use the latest available and proven technology which increase data storage and ease-of-use. They give longer life and enable PC and Internet connectivity. The on-board rechargeable lithium ion battery lasts for at least eight hours with the pump running continuously and for more than 12 hours in normal use. Against each unique location ID the G200 stores up to 1000 sets of readings of date, time and gases analysed. Data can be screen-viewed or transferred to Geotech’s optional Analyser Data Manager Software via PC-USB cable.

The G200 range has a crystal clear screen with an excellent backlight. Intuitive icons inform users on analyser set-up and status. If N2O levels exceed preset levels the analyser warns with an audible ‘bleep’ and the screen turns ‘alarm red’. Supplied standard with a battery recharger, carry case and instruction manual on a CD, options include the O2/CO electrochemical cell, a probe, the PC USB connector and Analyser Data Manager Software.
