INDUSTRIAL PRO HYDROGEN SULFIDE DETECTOR PRODUCT MANUAL
WARRANTY:
The Inspector has a one year warranty on all of its parts. It is recommended that you calibrate the Inspector every six
months. If you do not calibrate it then there is a good chance it will not provide an accurate measurement. If a calibration
is never performed an EOL (End of Life) icon will display on the LCD after two years of use. A successful calibration
postpones an EOL for 180 days.
NORMAL OPERATING CONDITIONS:
Temperature: -20oC to +50oC (-4 F to +122 F)
Humidity: 20-90% R.H (0-99% intermittent)
PRACTICAL CONSIDERATIONS:
Short term measurements (i.e. <1hr) in any humidity (0-99% R.H.) are fine as long as condensation does not block the
sensor inlet. A longer term exposure to extreme humidity outside the normal range can cause damage to the sensor.
Damage occurs much faster at higher temperatures. The LCD display and sensor will not work properly at lower
temperatures. NOTE: Higher temperatures can damage the device.
PLEASE NOTE:
Hydrogen Sulfide is a toxic gas that is produced from sour gas, bacteria, waste breakdown processes and other various
waste sources. The H2S Inspector is a professional tool that allows you to measure Hydrogen Sulfide levels.

Hydrogen Sulfide
Sensor Inlet
HOW THE INSPECTOR WORKS:
An electrochemical sensor behind the sensor inlet shown in the image above will create an electrical signal when
hydrogen sulfide (H2S) is sensed. The gas concentration is displayed in parts per million (PPM).
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.
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 flow 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.
