Portable Infrared Gas Analyser for Fume Hood and Ventilation Measurements

The InfraRan Analyser from Wilks Enterprise (USA) -- a portable, mid-infrared specific vapour analyser – is designed for easy, on-site measurement of sulphur hexafluoride (SF6) and is ideal for fume hood evaluations as per ASHRAE 110, as well as determining airflow in ventilation systems, rooms and buildings. The InfraRan Specific Vapour Analyser provides accurate, on-site, real-time measurements of SF6 and is factory calibrated for measuring SF6 in the 0 - 10 parts per million (ppm) concentration range with resolution to 0.01 ppm.

The InfraRan Specific Vapour Analyser has been designed to be a rugged, field portable instrument, weighing less than 18 lbs. It is ideal for both on-site survey studies and laboratory analyses. The analyser is factory calibrated for SF6 and operation is via user-friendly, menu-driven software enabling non-technical personnel, as well as industrial hygienists, to obtain easy, accurate measurements. The InfraRan Specific Vapour Analyser has an internal rechargeable battery for up to 8 hours of continuous field use or it can be operated from a 110/220V power source.

The analyser comes standard with both analogue and digital outputs. The analogue output is ideal for use with integrated ventilation software packages. 8 bit digital to analogue converter gives 0.01 ppm steps for the 0-2 ppm concentration range. The digital output allows real-time ASCII output of current data and download of data previously logged with InfraRan logging function.
