Portable oxygen purity tester

The instrument is being powered by rechargeable batteries and measure oxygen concentration through internal pump. It can be used to measure oxygen content in industries of building material and glass, oil pipeline project, nitrogen production by air separation, petrochemical process, Magnetic materials, high temperature sintering furnace protective gas, and rapid trace oxygen analysis for mixed gases.

The sensor react directly with gas which sample by pump when measure the oxygen content in the air, and generate linear varying voltage signal. The voltage signal is converted into digital signal and display in LCD screen, it will send out audible and visual signals when the gas concentration reaches alarm set point. The instrument has the function of battery low voltage alarm.

Features:

1.High-performance and ultra-low power consumption ARM processor, Intelligent management of the whole system.

2.Imported electro-chemical gas sensor, with the performance of long life-span,good stability,high accuracy,quick response speed.

3.Super large color touch screen, easy operation, massive content can be displayed.

4.Precise temperature compensation technology, with accurate measurement.

5.Audible and visual alarm function,the working status of the whole system can be learned clearly.

6.Self-test function, audible, visual,and LCD display fault warning function.

7.Reminding function for the due calibration time of the gas sensor

8.Printing and data record storage function

9.Data download function by the USB flash disk.
