Hydrogen Fluoride 1.5/b, 1.5 - 15 PPM, Part # CH30301, 10 Tests 

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 š pale pink

Ambient Operating Conditions

Temperature: 15 to 30 °C

Absolute Humidity: max. 9 mg H2O / L

Reaction Principle

HF + Zr(OH)4/Quinalizarin š [ZrF6]2- + Quinalizarin

Cross Sensitivity

In the presence of higher humidity (> 9 mg H2O / L), hydrogen fluoride 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.
