Following the PA6.0 residual oxygen analyzer, in order to make the gas industry users more convenient and effective to monitor the quality of production, the Shanghai WITT PA residual oxygen meter was successfully upgraded again. WITT has developed the latest product PA 7.0 for measuring O2 and CO2. The new product is a boutique that has been optimized and optimized for the old 6.0. 
PA 7.0 is used in a wide range of applications, such as protective gas for the measurement of food modified atmosphere packaging and welding. The highlight of the product is that it can perform two functions at the same time, that is, while continuously measuring the proportion of gas on-line, it can also be sampled and detected through a needle, similar to the detection of food modified atmosphere packaging. The multi-technology performance makes this device a leader in the industry.
Another advantage is that the amount of sample gas required is minimal. According to WITT, only about 3 ml of sample gas is required for different applications, and the ratio of sensors (electrochemical, yttria and infrared) can reach 0-100%.
The new 7.0 is an innovation that is reborn for the old 6.0. The company's R&D team has comprehensively optimized the old products, including the overall design from the shape to the internal structure, the design or selection of individual components and the software of the equipment. Almost no component in the old version 6.0 is still in the new model.
The redesigned stainless steel housing is aesthetically pleasing and easy to clean, making it ideal for industrial applications. The device panel has a USB interface and an SD card slot for extremely convenient data transfer.
The device's data interface is complete (digital input and output interface, 24V analog signal input and output interface, relay), which is convenient for communication with peripheral devices and integration with the user's overall system.
In addition, PA 7.0 has many properties, which is why it is an indispensable gas analyzer for gas industry quality control: if the device has reached the user preset limit, the analyzer will automatically generate an alarm or trigger a relay, such as Interrupt the air supply.
Electronic components such as high-quality pressure transmitters used in the analyzer continuously monitor the flow and automatically adjust the pump's power. If the sampling gas needle is blocked, the device automatically generates an alarm signal.
Measurement results can be saved by user or product classification. The internal memory holds the last 500 sets of measurement data. WITT's self-developed OBCC software ensures that all measurement results can be archived and analyzed.
The analyzer has less maintenance work and a 2-point calibration method, which is convenient and simple.
The device is compact in structure, small in size and light in weight, and is easy to place on the gas mixing site. The device is equipped with a handle for easy carrying. The adjustable bracket at the bottom ensures the optimum angle of placement of the device on the table.
