Features
- Various flammable gases can be measured in ppm order
- With the detection gas type switching function, 25 types of flammable gas can be detected by one unit.
- Supports long-distance suction with pump booster function
(suction flow rate: 0.3L / min⇒0.6L / min)
- Automatically switches between two types (Low / High) range display according to the measured value
- A cartridge type filter (sold separately) can be attached to the standard probe (filter type: for removing hydrogen sulfide, for removing silicon, etc.)
