4. Built-in large-capacity Data storage function, which can store up to 300,000 sets of data, and the storage interval is adjustable.
5. With USB interface, it supports high-speed data transmission and data download and printing.
6. Built-in long-life imported micro sampling pump, providing low, medium and high adjustable cleaning air circuit functions.
7. Passed the explosion-proof qualification certification, the explosion-proof level is Exia II CT4, and the shell is designed with a two-color mold that is non-slip, waterproof, dustproof and explosion-proof.
8. With self-calibration, zero-point calibration, multi-point calibration functions, and with temperature and pressure compensation.
9. Provide one key to restore factory settings, quick switching of gas concentration units, self-programming to set alarm parameters and STEL/TWA functions.
10. Support the usual detection and patrol two detection modes, with automatic gas cleaning and fault self-diagnosis prompt function.
Principle
The detector uses a pump-suction Sampling method, and the environment gas is sucked into the detection chamber through a built-in micro-sampling pump. The ethylene oxide component in the gas is detected by a professional infrared NDIR (non-dispersed infrared) Sensor. The Sensor converts the gas concentration signal into an electrical signal, which is conditioned by a High Accuracy, Low Temperature Drift amplifier and a stable power processing circuit, and is finally processed and displayed on the screen by a 32-bit ARM processor. The instrument has temperature and pressure compensation functions to ensure the accuracy of measurement under different environment conditions.
Applications
Industrial safety monitoring, confined space operation, environment emergency testing, medical sterilizing area monitoring, chemical production process monitoring
Steps
1. Boot warm-up: Turn on the device in a safe area 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 requirements, adjust the pumping speed of the sampling pump (low, medium and high) through the gear.
4. Start detection: Extend the sampling tube into the area to be tested, and the instrument will display the gas concentration value, STEL, TWA and MAX Maximum in real time.
5. Data viewing and export: You can view historical data through the menu, or connect to a computer through the USB interface to export and print data.
6. Calibration and setting: perform zero-point calibration, multi-point calibration on demand, or set alarm parameters through self-programming functions.
Notice
* Please make sure that the instrument has passed the relevant calibration and is within the valid period before use.
* Please use under the environmental conditions specified by the instrument (Temperature -30~ 50 ℃, Humidity 10~ 95% RH without condensation).
* Before entering the potentially dangerous environment, boot self-test and functional test should be carried out in the safe area.
* Pay attention to the Explosion-proof level of the instrument (Exia II CT4), and it is strictly forbidden to disassemble or charge it in dangerous places beyond the Explosion-proof level.
Regularly calibrate and maintain instruments to ensure detection accuracy.
* The sampling tube should be kept clean and open to avoid clogging affecting the test results.
When the instrument alarms, appropriate safety measures should be taken immediately and evacuated to a safe area.
* When not in use for a long time, please store the instrument in a drying, temperature suitable (-30~ 70 ℃) environment.
