- Designed for short-term, on-the-spot measurement
- Can take between 10 seconds to 15 minutes to gather a reading
- Applications may include concentration fluctuations in the workplace, measurement of contaminants in breathing zone, and confined spaces
- Can be used as pre-entry checks
Application Range Standard Measuring Range: 200 to 2,600 ppm R 113/R 114
100 to 1,400 ppm R 11
200 to 2,800 ppm R 22
(on request) 1,000 to 4,000 ppm R 134a
The indication is in mm and must be compared to the
calibration data sheets.
Number of Strokes n: 3 Time for Measurement: approx. 1 min Standard Deviation: ± 30 % Color Change: blue --> yellow to greyish green Ambient Operating Conditions Temperature: 0 to 40 °C Absolute Humidity: 1 to 15 mg H2O / L Reaction Principle For Example:
a) R113 [pyrolysis] --> HCI
b) HCI + pH indicator --> yellow reaction product
Cross Sensitivity Other halogenated hydrocarbons, free halogens and hydrogens halides are also indicated, however, with differing sensitivity. Perchloroethylene is indicated with the same sensitivity as R113. Additional Information The tubes become very warm during the measurement. Therefore, these tubes should not be used in potentially combustible atmospheres. A combustible gas monitor should be used to qualify any questionable area before conducting a measurement with one of these tubes.
