Main features

One click operation during the testing process: automatically completes the entire testing process, including vacuuming, sampling, heating, degassing, calculation, and oil discharge, without the need for manual intervention

The special pipeline design of the instrument can measure samples with high viscosity such as turbine oil

The instrument sampling port can be equipped with multiple interface forms, which are suitable for laboratory testing needs and can also be directly connected to the sampling port of the tested equipment for on-site testing, completely eliminating errors caused by the sampling process

The instrument pressure detection uses an absolute pressure sensor to directly measure the absolute pressure value, combined with multiple compensation algorithms to compensate for the numerical deviation caused by changes in the testing environment, making the test results more accurate

The vacuum pump is automatically controlled by the instrument to start and stop, effectively reducing the running time of the pump, reducing noise and other pollution, and improving the service life of the pump

■ Built in oil pump, no need for external compressed air source

Before formal testing, the pipeline can be automatically cleaned once to improve testing accuracy

The testing process parameters can be set and changed by users to adapt to various sample testing
