INTRODUCTION

First Responder CG is the combination instrument for first
call and emergency response technicians in the gas utilities
industry.
Fig. 1-1 First Responder CG
The instrument is a highly flexible, four button portable gas
detector which is designed to provide measurement of LEL
and Volume flammable gas for leak detection and general
safety monitoring. The First Responder also features a
Carbon Monoxide (CO) range, a Hydrogen Sulphide (H2S)
range, and Oxygen (O2), for internal atmosphere monitoring
where odour call response is required.
The First Responder CG also features a Parts Per Million
(PPM) range to increase sensitivity to smaller leaks. This is
achieved using the external (EXT) semiconductor sensor
located at the end of the 'flexi' probe, that provides a near
instantaneous response in detecting small fitting leaks.
