In daily life, sulfur dioxide is a very common and irritating sulfur oxide, which is one of the main pollutants in the atmosphere. In order to better prevent the harm caused by sulfur dioxide, we usually use a sulfur dioxide detector as standard. The sulfur dioxide detector can be used for mobile fast and accurate detection and reading of sulfur dioxide gas concentration, temperature and humidity measurement and excessive alarm occasions. Do you know the performance characteristics of sulfur dioxide detector ? The following is a brief introduction by yi yun Tian:

sulfur dioxide detector performance characteristics:

1, Completely waterproof, dustproof, explosion-proof, shockproof, intrinsically safe circuit design, antistatic, anti-electromagnetic interference, through the national standard test and CMC measuring instrument production license certification, protection level IP67, can prevent rain and short-term immersion, built-in replaceable water vapor, dust filter, can be used in high humidity, high dust occasions without damaging sensors and instruments.

2, built-in pump suction measurement, integrated water vapor and dust filter, optional professional accessories for high temperature, high humidity and high dust environment, rapid response; Special road design, sampling distance is more than 10 meters high.

3. the high-definition 2.5-inch color screen displays real-time concentration, alarm, time, temperature, humidity, storage, communication, printing, power, charging status and other information. the menu interface uses high-definition simulation icons to display the function names of each menu.

4, mass data storage function, support 100000 pieces of data storage capacity, larger capacity can be customized. Optional SD card storage function, support real-time storage, timing storage or only alarm concentration data and time, support the local view, delete data, can also be through USB, infrared communication, RS232 The interface uploads the data to the computer, and uses the upper computer software to analyze the data, store and print.Support remote wireless transmission (optional function).

5, infrared communication interface (optional), USB interface, RS232 interface automatic identification, optional external micro wireless, infrared printer, printing: company name, gas name, date and time, ambient temperature and humidity, concentration data, test results (qualified).

6, USB charging interface, can be charged by computer or charging treasure, compatible with mobile phone charger, overcharge, overdischarge, overvoltage, short circuit, overheat protection, level 5 accurate power display, support USB hot plug, detector can work normally during charging.

7, using 6000mAH large capacity rechargeable polymer battery, can work continuously for a long time.

8, sound and light alarm, vibration alarm, visual alarm, undervoltage alarm, fault alarm, multi-directional stereoscopic display of alarm status when alarming.

9. The alarm value can be set, and the alarm mode can be selected from low alarm, high alarm, interval alarm and weighted average alarm.

10, high-precision temperature and humidity measurement (optional), and temperature compensation for the sensor. the instrument uses a temperature range of -40~70 degrees and can detect 1300 degrees of gas (optional high-temperature sampling and cooling filter handle or high-temperature and high-humidity pretreatment system).

11. it can be detected in real time or regularly (for the case where the amount of measured gas is relatively small). when not detected, the pump can be turned off to prolong the startup time.

12, can choose to detect 1~6 kinds of gases at the same time, up to 8 kinds of gases, the unit is free to switch, conventional gases do not need to input molecular weight, special gases need to input molecular weight to automatically calculate and switch, the unit is optional: PPM, mg/m3, Vol%, LEL%, PPHM, ppb, mg/L.

13, three display modes can be switched: 4 gas concentration can be displayed at the same time, single-channel gas concentration and real-time curve can be displayed in large letters, automatic circulation or manual circulation can be switched between channels, whether to display value and gas name can be set, and historical graph can be viewed.

14, Chinese and English interface can be switched, the default Chinese interface, concise Chinese or English operation tips, users of all ages can easily operate.

15, data recovery function, optional recovery or full recovery. The misoperation of concentration calibration is automatically identified and prevented to avoid the bad caused by human factors.

16, zero automatic tracking, multi-level calibration of target points, to ensure the linearity and accuracy of measurement. It can also meet the national standards and local standards of the Bureau of Metrology.

17, can record calibration log, maintenance log, fault resolution countermeasures, sensor life expiration reminder, next concentration calibration time reminder function.

In summary, some of the performance characteristics of the sulfur dioxide detector. In order to ensure the accuracy of the data and better application of sulfur dioxide detector, we must select the appropriate detection principle, range and precision of sulfur dioxide detector according to the characteristics of the field use environment and the purpose of detection.
