HOW THE INSPECTOR WORKS:
An electrochemical sensor behind the
sensor inlet
shown in the
image
above
will create an electrical signal when
hydrogen sul
fi
de (H2S) is sensed. The gas concentration is displayed in
parts per million
(PPM).
HOW TO PERFORM A SELF CALIBRATION:
For reasonable accuracy a frequent calibration is recommended at least once every 6 months. Sensorcon will
perform this procedure for you or you can do it yourself if you have the necessary 15ppm calibration gas.
Please follow these steps to self calibrate your Inspector:
1.
Hold
both
buttons for 5 seconds to enter calibration mode. Press the
MUTE
button at any time to exit.
2.
In a clean air environment then press the
MAX
button to begin the
ZERO
calibration. Wait for countdown.
3.
When zero is complete, use 1/4” OD, 1/8” ID Tygon tubing attached to the calibration gas cylinder and
sensor inlet to
fl
ow calibration gas at 0.5L/min, then press the
MAX
button to start calibration process.
4.
The Inspector will then automatically calibrate itself and notify you if a calibration is successful.
Please feel free to contact us if you have any further questions or are in need of technical assistance.
Please Note:
The Sensorcon Inspector is a professional tool. It does not require very much maintenance with the exception of keeping it clean.
This is especially important in the area of the sensor inlet. If it gets dirty then simply wipe it clean with a damp cloth or with a damp cotton swab.
