Handling, Storage, and Calibration of HF and HCL Sensors
1.
Sensors must not be stored, assembled or installed in areas that contain solvent vapors.
Especially at high concentrations, the organic solvents are known to cause:
l
Blocking of the sensing electrodes
l
Creation of false baselines
l
In some cases, damaging of the electrodes
l
Physical damage of the sensor body
A sensor must not be exposed to temperatures outside the range of -55° C to + 60° C (-
67° F to +140° F).
2.
It is recommended that sensors be stored in the originally sealed packaging at +4° C to
+10° C (39° F to +50° F), with the sensors’ gas inlet side (membrane/filter side) pointing
downwards.
3.
Avoid storing the instrument for more than 12 hours in a way that sensors will be have
their gas inlet side pointing upwards (equivalent to the instrument’s screen pointing
downwards).
HF & HCL Sensor Calibration
It is important to understand and acknowledge that HF and HCl sensors are not as easy to use
and calibrate as any other EC (electrochemical) sensors, so we recommend strictly following the
process described in RAE Systems by Honeywell Technical Note TN-201.
In addition, be aware that environmental conditions in end-users' applications, legal
requirements, and the level of requested accuracy of the gas detection device towards the target
gas determine the frequency of recalibration of the sensors.
