CH30301 หลอด Tube วัดสารเคมีประเภท Hydrogen Fluoride 1.5/b ยี่ห้อ Draeger
Model : 75-1715
Model (old) : 62-1700-H15
Application Range
Standard Measuring Range: 1.5 to 15 ppm
Number of Strokes n: 20
Time for Measurement: approx. 2 min
Standard Deviation: ± 15 to 20 %
Color Change: pale blue -> pale pink
Ambient Operating Conditions
Temperature: 15 to 30 °C
Absolute Humidity: max. 9 mg H2O / L
Reaction Principle
HF + Zr(OH)4/Quinalizarin -> [ZrF6]2- + Quinalizarin
Cross Sensitivity
In the presence of higher humidity (> 9 mg H2O / L), hydrogenfluoride mist is generated, which cannot be quantitatively indicated by the detector tube (i.e. the indication is too low). Other halogenated hydrocarbons in the TLV range do not interfere.
