With the development of the economy, there are more and more chemical companies, and there are more and more dangerous accidents such as chemical gas leakage. As a result, the gas alarm industry is becoming more and more popular. Nowadays, more and more enterprises of various industrial enterprises use gas detection and alarm systems. In order to prevent personnel poisoning and protect public property, gas detection and alarm systems have become "protective umbrellas". Therefore, it is very important to choose a gas alarm suitable for your company.

Features of gas four-in-one detector:

● Waterproof splash, dustproof, explosion-proof, shockproof, intrinsically safe circuit design, anti-static, anti-electromagnetic interference, passed the standard test and CMC measuring instrument production license certification

● Protection type IP65, built-in water vapor and dust filter, to prevent damage to sensors and instruments due to water vapor and dust

● Built-in pump-type measurement, quick response, sampling distance greater than 10 meters, special gas circuit design, can directly detect negative or positive pressure -0.5 ~ 2 kg of gas, no impact on the measurement results

● The 2.31-inch clear color screen displays real-time concentration, alarm, time, temperature, humidity, storage, communication, power, charging status and other information. The menu interface uses clear simulation icons to display the function names of each menu

● Large-capacity data storage function, standard 100,000 data storage capacity, larger capacity can be customized. Support real-time storage, regular storage, or only save alarm concentration data and time, support local machine to view and delete data, and also upload data to computer through USB interface, use upper computer software to analyze data, store and print.

● USB charging interface, can be charged by computer or power bank, compatible with mobile phone charger, overcharge, overdischarge, overvoltage, short circuit, overheat protection, 5 accurate power display, support USB hot swap, the detector can work normally while charging , Optional RS485 communication.

● Using 4500mA large capacity rechargeable molecular polymer battery, can work continuously for a long time

● Sound and light alarm, vibration alarm, visual alarm, undervoltage alarm, fault alarm, multi-dimensional display of alarm status during alarm.

● Alarm value can be set, the alarm mode can choose low alarm, alarm, interval alarm, weighted average alarm.

● Precision temperature and humidity measurement (optional), at the same time temperature compensation for the sensor, the instrument uses a temperature range of -40 ~ 70 degrees, can detect 400 degrees of gas, more temperature gas detection can be customized (optional temperature sampling cooling filter handle Or temperature and humidity pretreatment system).

● It can detect 1-4 kinds of gas at the same time, the unit can be switched freely, the molecular weight of conventional gas does not need to be input, and the molecular weight of special gas needs to be automatically calculated and switched. The unit can be selected: PPM, mg/m3, Vol%, LEL%, PPHM, ppb, mg/L.

● Three display modes can be switched: simultaneous display of four gas concentrations, large font cycle display of single channel gas concentration, real-time curve, automatic cycle or manual cycle between each channel can be switched, can set whether to display large value, small value, Gas name, you can view the historical record curve.

● Chinese and English interface can be selected, the default Chinese interface, simple Chinese or English operation tips.

● Data recovery function, you can selectively recover or all recovery, avoiding the worries caused by misoperation

● Zero automatic tracking, long-term use is not affected by zero drift.

●Target point three calibration, to ensure the linearity and accuracy of the measurement, can meet the standards and local metrology bureau standards.

● Concentration calibration misoperation is automatically identified and prevented, which can avoid the defects caused by human factors.

● Real-time detection or timing detection (for the case where the amount of gas to be measured is relatively small), when not detected, the pump can be turned off to extend the start-up time.

●Can record calibration log, maintenance log, fault resolution countermeasures, sensor life expiration reminder, next concentration calibration time reminder function

As a powerful brand in the gas detector market weather body detector, since its introduction into the market, it has been favored by more and more customers with its three leading advantages of quality leading, technology leading and after-sales leading.
