Features

• For High Concentration Measurement
• BASE gas can be selected! All 5 Types of Gases Can Be Detected/Concentration Direct Reading with One Unit!!
• BASE gas (Air, N2, CO2) can be selected.
• Measurement Gas Type (Methane, Propane, Isobutane, Argon, Helium) Switchable
• Automatic Range Switching Type (Low range: 0-10.0vol%%%%⇔High range: 0-100vol%%%%/2 ranges of Low/High are automatically switched according to the measured value.)
• 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.)
