The DrägerSensor XS EC HF/HCl precisely measures the concentration of hydrogen fluoride and hydrogen chloride and warns of hazardous gas concentrations.

The sensor is replaceable and can only be used in the Dräger X-am 5100
Expected service life of more than 1.5 years, supplied with a one-year warranty
Fast response time ≤ 60 seconds (t₅₀), warm-up time ≤ 1 hour
Operating conditions: −20 to 40 °C, 30 to 90 % RH, 700 to 1,300 hPa

Technical data – DrägerSensor XS EC HF/HCl

Detection limit	1 ppm
Resolution	0.1 ppm
Measuring range	0 to 30 ppm
Response time	≤ 60 seconds (t₅₀)
Accuracy (sensitivity)	≤ ± 15 % of the measured value
Long-term drift at 20 °C (68 °F)	Zero point: ≤ ± 0.5 ppm/month Sensitivity: ≤ ± 5 % of the measured value/month
Warm-up time	≤ 1 hour
Environmental conditions	Temperature: −20 to 40 °C Humidity: 30 to 90 % RH Pressure: 700 to 1,300 hPa
Effect of temperature	Zero point: ≤ ± 0.5 ppm Sensitivity: ≤ ± 10 % of the measured value
Effect of humidity	Zero point: no effect Sensitivity: ≤ ± 2 % of the measured value/% RH
Test gas	HCl test gas between 5 and 30 ppm

Alternatively, the target gases HNO3, HBr, POCl3, PCl5 or HF may also be used. A function test should be carried out before every use; the criterion is that a reading of more than 0.5 ppm HCl is expected after 30 seconds.

Relevant cross-sensitivities – DrägerSensor XS EC HF/HCl

The values given in the table are guide values and apply to new sensors. The values stated may vary by ±30%. The sensor may also be sensitive to other gases (data available from Dräger on request). Gas mixtures may be displayed as a combined total. Gases with a negative sensitivity can cancel out a positive HCl/HF reading. It should therefore be checked whether gas mixtures are present.

Gas/vapour	Concentration	Reading in ppm HCl
Ammonia (NH3)	500 ppm	no effect
Carbon monoxide (CO)	150 ppm	no effect
Chlorine (Cl2)	5 ppm	≤ 22
Hydrogen (H2)	1.5 vol.%	no effect
Hydrogen cyanide (HCN)	20 ppm	≤ 9
Sulphur dioxide (SO2)	20 ppm	≤ 20
