IG5 Indicator Gas No.5 gas detector as used in the telecom industry

The Indicator Gas No.5 (IG5) gas detector as historically used in the telecom and CATV industry is a portable device for the detection of flammable and explosive gases. The instrument is of the hand aspiration type and may be used to sample an atmosphere prior to entry into a confined space.

The IG5 is supplied complete with a 15 foot hose, a surface disturbance probe (probe gas testing) and an inline water trap all housed in a robust ABS carring case

The IG5 detects flammable and explosive gas concentrations in the range 0-100% of the lower explosive limit (LEL), it should not be used to detect high concentration of flammable gas.
The IG5 will not detect asphyxiating or toxic gases.
Use strictly in accordance with the instructions.
