Description
FI-8000
The FI-8000 is an optical interferometer which is used for measuring gas concentration or calorie of flammable gases in hazardous location. It has two different suction styles, one is manual aspirating with squeezing a rubber bulb and other is automatic suction by an internal micro pump. The battery can be selected either Li-ion battery or alkaline dry battery. Li-ion battery unit is called BUL-8000(F), BUL-8000(F1) and alkaline dry battery unit is called BUD-8000(F). The battery unit structured in a way, that even the end user is possible to replace it.
