120UH HYDROGEN SULPHIDE
(NOTE)
1. Where the discolouration is over the scale, non-reacted Hydrogen sulphide remains in the pump. This residual
Hydrogen sulphide is not exhausted even if the pump handle is pushed back, and it still remains in the pump.
When the handle is pulled next, it is exhausted toward the operator from the stopper side of the pump.
Accordingly, air purging of the pump inside by pulling/pushing the handle several times should be done in
fresh air where there is not Hydrogen sulphide, because Hydrogen sulphide is very toxic. During the air
purging, protection apparatus such as a gas mask should be worn.
2. Maximum sampling volume of the gas shall be approximately 70mr.
