Multi Gas Detection Equipment for Quick Oxygen Nitrogen Sulfide Testing and Warning

Product Description

 

Feature of KDZD400Q 4 in 1 Multi Gas Detector:
1. Can detect 1~4 gases at the same time.
2. Built-in pump-type measurement, integrated water vapor and dust filter, fast response, support long distance.
3. 2.31-inch high-definition color screen, display real-time concentration, alarm, time, temperature, humidity, storage, communication, power, charging status, concentration unit, gas molecular formula, gas name and other information.
4. Large-capacity data storage function, support multiple storage methods: standard 100,000 data storage capacity, larger capacity can be customized.
Support local viewing and deletion of data, and can also upload data to the computer through the USB interface, use the host computer software to analyze data, store and print. Optional RS485 communication.
5. High-temperature gas detection (optional). Higher temperature gas detection can be customized.
6. Three display modes can be switched: simultaneous display of four gas concentrations, large font cycle display of single-channel gas concentration, real-time curve.
7. Graphical display: Reflect the trend of gas concentration changes over a period of time in the form of a curve.
8. Data recovery function. You can choose to restore part or all of the data.
9. You can set whether to display the maximum value, minimum value, and average value.
10. USB charging interface with charging protection function.
11. It uses a 4500mA large-capacity rechargeable polymer battery, which can work continuously for a long time.
12. High-precision temperature and humidity measurement (optional). At the same time, the sensor is temperature compensated. The instrument uses a temperature range of -40~70 degrees.
13. Supports real-time detection or timed detection. When not detecting, the pump can be turned off to extend the startup time.
14. Multiple alarm modes, multi-directional three-dimensional indication of the alarm status when alarming: including sound and light alarm, vibration alarm, and visual alarm. Alarm types include: concentration alarm, undervoltage alarm, and fault alarm.
15. The alarm value can be set, and multiple alarm modes are set: low alarm, high alarm, interval alarm, and weighted average alarm.
16. Misoperation recognition function: Concentration calibration misoperation is automatically recognized and prevented, which can avoid the defects caused by human factors.
17. Zero point automatic tracking: Long-term use is not affected by zero point drift.
18. Target point multi-level calibration: Ensure the linearity and accuracy of the measurement, and can meet the national standards and local metrology bureau standards at the same time.
19. Log record: record calibration log, maintenance log, fault solution countermeasures, sensor life expiration reminder, next concentration calibration time reminder function.
20. Meet the requirements of intrinsically safe circuit design, anti-static, anti-electromagnetic interference, pass the national standard test and CMC metrology instrument production license certification
21. The protection level reaches IP65, which is splashproof, dustproof, explosion-proof and shockproof.
