Industrial gases are usually classified as Class 2 compressed gases and liquefied gases in the national standard "Classification and Marking of Commonly Used Hazardous Chemicals" (GB13690-1992). Such chemicals refer to compressed, liquefied or pressurized dissolved gases. By pressurizing or lowering the temperature of the gas, the distance between the gas molecules can be greatly reduced and pressed into the cylinder. This gas is called compressed gas, also known as permanent gas, Argon is one of them.

How to choose an argon concentration measuring instrument? Yiyuntian technicians recommend using the following suitable argon concentration measuring instruments: hand-held argon detector, portable Argon detector, portable argon detector, fixed argon detector, online argon detector, etc.

PTM600-Ar with a portable argon detector For example, Yiyuntian PTM600 portable argon analyzer is used for mobile occasions that require accurate detection and analysis of argon concentration, temperature and humidity measurement. The 3.5-inch high-definition color screen is used to display the concentration in real time, and the gas sensor based on electrochemical or infrared, catalytic combustion, thermal conductivity, PID light ion principle and Swiss high-precision capacitive digital temperature and humidity sensor of the best brand in the industry are used.PTM600 advanced circuit design, mature kernel algorithm processing, has made a number of software patents and appearance patents.

PTM600 portable argon analyzer features:

● waterproof, dustproof, explosion-proof, shockproof, intrinsically safe circuit design, antistatic, anti-electromagnetic interference, passed the national standard test and CMC measuring instrument production license certification.

● protection level IP66, built-in water vapor and dust filter to prevent damage to sensors and instruments due to water vapor and dust

● built-in pump suction measurement, rapid response, sampling distance greater than 10 meters, special gas path design, can directly detect

positive pressure or negative pressure -0.3~2kg of gas, which has no effect on measurement results.

● 3.5-inch HD color screen displays real-time concentration, alarm, time, temperature, humidity, storage, communication, printing,

power, charging status and other information. The menu interface uses HD simulation icons to display the function names of each menu.

● large-capacity data storage function, standard 100000 data storage capacity, larger capacity can be customized.Optional U disk storage or SD card storage function, support real-time storage, timing storage or only alarm concentration data and time, support the machine to view and delete data, but also 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.

● infrared communication interface, USB interface, RS232 interface automatic identification, optional built-in or external wireless infrared printer, print content: company name, gas name, date and time, ambient temperature and humidity, concentration data, test results (qualified).

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

● Using 10000mA large-capacity rechargeable polymer battery, it can work continuously for a long time.

● Sound and light alarm, visual alarm, undervoltage alarm, fault alarm, multi-directional stereoscopic display of alarm status when alarming.

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

● High-precision temperature and humidity measurement (optional), and temperature compensation for the sensor. The temperature range of the instrument is -40~70 degrees, and the gas of 1300 degrees can be detected (optional high-temperature sampling and cooling filter handle or high-temperature and high-humidity pretreatment system).

● can detect 0.001PPM at the lowest and 99.999 Vol at the highest, and support automatic switching between high and low ranges (to be noted when ordering).

● 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 extend the startup time.

● can be selected to detect 1~6 kinds of gases at the same time, up to 18 kinds, the unit is free to switch, conventional gases do not need to input molecular weight, special gases. If you need to enter the molecular weight, it will 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: simultaneously displaying the concentration of the 4 gas, displaying the concentration of the single-channel gas in large letters, real-time curves, and each channel. Between automatic cycle or manual cycle can be switched, you can set whether to display the maximum value, minimum value, gas name, you can view the history graph.

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

● Data recovery function can selectively recover or fully recover, and the misoperation of concentration calibration can be automatically identified and prevented to avoid the bad caused by human factors.

● Zero automatic tracking, multi-level calibration of the target point, to ensure the linearity and accuracy of the measurement, and can meet the national standards and local standards of the Bureau of Metrology.

● can record calibration log, maintenance log, fault solving countermeasures, sensor life expiration reminder, and next concentration calibration time reminder function.

according to the gas generation characteristics of the industry, yiyuntian has targeted and independently developed argon gas detector equipment, which can monitor the concentration change of the gas 24 hours a day and set the secondary alarm value to ensure the rapid response of the operators. At present, Yiyuntian argon concentration measuring instrument has been widely used in petroleum, chemical, pharmaceutical, environmental protection, flue gas analysis, air treatment and other occasions that need to detect and analyze gas concentration.
