Four Gas (Confined Space Entry) Detectors
A four gas detector is known as a confined space entry gas detector. These are most commonly used prior to entry into a confined space to determine hazardous gas levels. a1-cbiss supplies a range of confined space entry gas detectors which give you a measure of indication that it is safe for you or your colleagues to enter into an environment.
Four gas detectors are used to detect carbon monoxide, hydrogen sulphide, oxygen deficiency and combustible gases. A pumped gas detecting instrument coupled with a sampling line is used to perform a pre-entry check.
a1-cbiss support the RAE Systems, BW, Industrial Scientific, 3M Scott Safety and GMI confined space entry gas detector product ranges.
