Principle
The Portable hydrogen sulfide detector works based on the principle of Electrochemical sensor. The sensor converts the concentration of hydrogen sulfide gas in the environment into an electrical signal. After the signal is amplified by a two-stage High Accuracy cryogenic drift amplifier and processed by a stable power supply circuit, it is analyzed and calculated by a 32-bit ARM processor. Finally, the concentration value is displayed in real time on the display screen. The instrument has a built-in micro-sampling pump to actively extract gas samples, and through temperature and pressure compensation algorithms, it ensures the accuracy of measurement results under different environment conditions.
Applications
Industrial safety monitoring, environment monitoring, confined space operations, Petrochemicals, sewage treatment, mining, emergency rescue
Steps
1. Boot warm-up: Press the power button for a long time to turn it on and wait about 30 seconds for the warm-up to complete.
2. Mode selection: Select the normal detection mode or patrol mode through the menu.
3. Sampling settings: according to the detection environment, adjust the pumping speed of the sampling pump (low, medium and high) through the gear.
4. Start detection: Place the sampling tube in the area to be tested, and the instrument automatically displays the real-time gas concentration.
5. Data viewing: View historical data, STEL, TWA values, or real-time trend graphs through the menu.
6. Data export: Connect to a computer via USB to download or print stored data.
7. Calibration and setting: Regularly use standard gas for zero or multi-point calibration, and alarm parameters can be set through self-programming function.
Notice
• Please ensure that the instrument is fully charged before use and operate within the range of Ambient Temperature (-30~ 50 ° C) and Humidity (10~ 95% RH without condensation) specified in the manual.
• Avoid use in environments with strong electromagnetic interference, high corrosion or flammability gas concentrations to prevent damage to the instrument or cause danger.
• Calibrate Sensors regularly, at least once a year is recommended to ensure Measurement accuracy.
• The sampling tube should be kept clean and open to avoid clogging affecting the test results.
• Instruments are designed to be explosion-proof, but must not be disassembled or modified in hazardous locations beyond the Explosion-proof level.
• When not in use for a long time, please shut down and store in a drying and dark environment. Temperature range is -30~ 70 ℃.
• If the instrument indicates failure, Sensor failure or calibration expires, it should be sent for repair or contact a professional in time.
