คุณลักษณะ

For High Sensitivity Measurement
All 22 types of gases including methane, hydrogen, BTX(Benzene, toluene, and xylene) and alcohol can be detected/directly read with 1 unit (measurement gas type switching function is included as standard)
Pump capacity switching function (pump booster function supports long-distance suction 0.3 L/min⇒0.6 L/min)
Automatic Range Switching Type (Low range: 0-1000ppm⇔High range: 0 -10,000 ppm/2 types of low/high range are automatically switched according to the measured value.)
Intrinsically safe explosion-proof structure
Dustproof and waterproof structure for outdoor work (equivalent to protection grade IP 67)
Standard probe can be equipped with a cartridge filter (sold separately) (hydrogen sulfide removal filter and silicone removal filter can be mounted. The probe can be arranged for use in workplaces where hydrogen sulfide or silicone can damage the sensor.)
This product comes with a traceability certificate. Breakdown of attached documents: gas inspection report (acceptance certificate issued by gas manufacturer), traceability system (traceability system diagram for gas production), traceability chart (traceability system diagram for equipment and measuring instruments)
