Fast, reliable and specific detection of hydrofluoric acid (HF) is indispensable in many manufacturing environments. The model HFT and HFM sensors detect HF by its etching action on an anodic Silicon dioxid film covering the sensor electrode. These electrochemical sensors are therefore specific to the presence of HF in the solution.

Outline
The HFT-sensor is designed as a safety-tool to detect hydrofluoric acid in liquids of unknown composition within a second. A bright red LED indicates the presence of HF.


Specifications
Sensitivity 1% - 50% HF
Sensor lifetime > 1000 tests
Power supply 2 x 3V Lithium Batt.
Temperature range 0° - 50° Celsius

Outline
The HFM-meter is designed for single and continuous measurements of the concentration of hydrofluoric acid solutions. By simultaneous measurement of solution temperature and activity the computed value displayed is corrected for temperature. The HFM-meter is equipped with a touch screen display for simple menu selection.


Specifications
Concentration range 0.1% - 1 % HF (rel. Error 20%)
1% - 15 % HF (rel. Error 10%)
15% - 50 % HF (rel. Error 30%)
Response time < 15 seconds
Sensor lifetime > 10.000 single measurements
Temperature range 0° - 50° Celsius
