Principle
The Portable ethylene oxide detector uses the pump-suction Sampling method, which actively sucks the environment gas into the detection gas chamber through the built-in micro-sampling pump. The gas contacts the imported Electrochemical sensor inside the instrument, and the Sensor generates a corresponding electrical signal according to the concentration of ethylene oxide. The signal is amplified by a High Accuracy, Low Temperature Drift amplifier, processed by a stable power processing circuit, and finally analyzed and calculated by a core system based on a 32-bit ARM processor. The gas concentration value is displayed on the screen in real time, and an alarm is triggered when the concentration exceeds the standard.
Applications
Industrial safety monitoring, environment emergency testing, confined space operation, disinfection area of medical and health institutions, warehousing and logistics, laboratory safety
Standards
Explosion-proof certification (Exia ⅱ CT4)
Steps
1. Boot warm-up: Press the power button for a long time to turn it on, and the instrument will warm up for about 30 seconds.
2. Select mode: Select "normal detection mode" or "patrol mode" through the menu.
3. Set parameters: Set alarm values, STEL, TWA and other parameters through self-programming functions as required.
4. Start detection: place the sampling tube in the area to be tested, the instrument automatically pumps the gas for detection, and the screen displays the concentration value in real time.
5. Data recording: The detection data is automatically stored, and the data can be exported by connecting to the computer through the USB interface.
6. Gas path cleaning: After the detection is completed, the high-end function of the sampling pump can be used to clean the gas path.
7. Shutdown: Long press the power button to turn off the instrument.
Notice
* Please ensure that the instrument is fully charged before use and used within the range of Ambient Temperature (-30~ 50 ° C) and Humidity (10~ 95% RH without condensation) specified in the manual.
* Avoid long-term use in strong electromagnetic interference, high concentration dust or corrosion gas environment to prevent damage to Sensor or instrument.
* Regularly zero calibration and Sensor calibrating to ensure detection accuracy, the instrument has self-calibration and calibration expiration prompt function.
* When sampling, pay attention to the smoothness of the sampling tube to avoid bending or blockage affecting the detection results.
* The instrument is designed to be explosion-proof, but must not be disassembled or repaired in hazardous locations beyond the Explosion-proof level.
* Data storage is full, please export data in time to avoid overwriting old data.
* If the instrument malfunctions or alarms abnormally, please refer to the instructions or contact a professional, and do not disassemble it yourself.
* When not in use for a long time, please shut down and store in a drying environment. Temperature range is -30~ 70 ℃.
