Komyo Rikagaku Gas Detector Tube Hydrogen Sulfide 10 Tubes 120U 1 Box

Catalog number: 120U Features: ●Direct reading type, so there is little individual variation. Uses: ●Hydrogen sulfide detector tube. ●For measuring work environment. Specifications: ●Target gas: Hydrogen sulfide ●Measurement range (ppm): 0.1 to 6.0 ●Validity period (years): 2 ●Sample collection and measurement range: 50mL (temperature compensation value x 2: 0.2 to 6.0 ppm) 100mL (printed scale: 0.1 to 3.0 ppm) ●Measurement time: 1 minute/100mL ●Detection limit: 0.05 pm (when 100mL is collected) ●Color change: Light yellow to pink ●Reaction principle: Reacts with silver compounds to produce acidic substances, causing the indicator to change color. ●Changes over time: The boundary of the discoloration becomes unclear and the indication becomes higher. ●Effect of humidity: None ●Calibration method: Permeation tube method Caution: ●Please note that calibration may not be possible depending on the type of gas. ●The number of measurements varies depending on the detector tube used.
