What are the advantages of portable multi-gas detectors in practical operation?
Portable multi-gas detectors are frequently used tools for leak checking in gas storage areas. Particularly suitable for use in process equipment, around piping systems and into confined spaces. One-handed operation, the instrument includes a built-in pump and a sampling soft rod, large characters, and a backlight display to ensure that the detected gas concentration values can be clearly read in dark and dark environments.
The outstanding feature of this instrument is that it can detect many types of gases by changing the corresponding sensor module. That is, there is no need to purchase a separate host for each type of gas. One detector can be used in combination with different sensors to detect more than 30 different gases or vapors. The sensors can be plugged and played without recalibration.
The sensor uses a new lightweight sensor module, each sensor module is a composite device with a sensor, amplifier and memory module inside. Based on this design, each sensor module can be independently calibrated and plug-and-play. If it is installed in a host and the corresponding calibration data is input to the microprocessor, there is no need to make adjustments. No recalibration is required every time the sensor is replaced when using gas.
Advantages of using portable multi-gas detectors:
1. The detector adopts advanced ultra-low power consumption 16-bit microcontroller;
2. Ultra-wide viewing angle graphic liquid crystal display;
3. High and low alarm points can be set, two-level alarm, and the screen displays the alarm type;
4. The calibration concentration value is adjustable, which is convenient for users to calibrate;
5. High concentration protection function of combustible gas sensor;
6. Self-check of combustible gas sensor fault;
7. Battery undervoltage prompt;
8. Provide real-time clock display;
9. Replaceable modular sensors;
10. Automatic calibration function to reduce detection error;
11. Two-level triple alarm (sound, light, vibration), not easy to ignore;
12. With data communication function;
13. There are STEL and TWA alarms for toxic gases;
14. Power-on self-test function, and has advanced self-diagnosis and self-repair functions;
15. Password management function, important operations require password verification to effectively prevent misoperation;
16. Intrinsically safe instruments.
