Delger detection tube

*It is an inorganic compound with the chemical formula H2O2. Pure * is a light blue viscous liquid that can be mixed with water in any proportion. It is a strong oxidant, commonly known as hydrogen peroxide in aqueous solution, and is a colorless and transparent liquid. Its aqueous solution is suitable for medical wound disinfection, environmental disinfection, and food disinfection. In general, it slowly decomposes into water and oxygen, but the decomposition rate is extremely slow, accelerating its reaction rate.

★ Determine * (H2O2) in air or technical gases.

★ Measurement range: 0.1 to 3 ppm 1 ppm

★ Number of strokes (n): 20 2

★ Measurement duration: approximately 3 minutes. approximately 18 seconds

★ Standard deviation: ± 10-15%

★ Color Change: White → Brown

★ Temperature: 10 ° C to 25 ° C

★ Humidity: 3 to 10 mg/L (equivalent to 50% relative humidity at 23 ° C)

Correction factor: F=1013/actual air pressure (hPa).

2 H2O2 + 2 KI → I2 + 2 H2O + O2

The working principles of the test tube and Dr ä ger gas detection pump are coordinated with each other. Using other pumps may impair the normal function of the test tube.

Please pay attention to the instructions for using the pump (seal test!).

The measurement value is only applicable to the measurement location and measurement time point.

1. Break two tubes in the Dr ä ger tube opener.

2. Insert the test tube tightly into the pump. The arrow points to the pump.

3. Extract air or gas samples through a test tube.

4. Read the color change of the entire length.

5. Multiply the numerical value by the pressure correction factor F.

6. Pay attention to possible cross sensitivity.

7. Rinse the pump with air after use.

1 ppm H2O2 = 1.4 mg H2O2 /m3

1 mg H2O2/m3=0.71 ppm H2O2 (at 20 ° C, 1013 hPa)
