The test device TWIN CHECK 4⋅0 is developed for regular on-board measurement of two crucial oil parameters: water-in-oil and base number (BN).

The concentration of water in oil can be determined in the range from 0-1⋅0 vol % H2O and the BN value can be measured from 0 to 150 BN.

This video manual shows the detailed procedure for measuring the base number (BN) with the TWIN CHECK 4⋅0.

The digital test device from Martechnic offers an optimised measurement process, precise determination of measuring times in accordance with the measured value, and automatic measurement cut-off.

A large memory capacity for data storage and USB to serial connection (terminal program) enables conducting trend analysis and direct on-board evaluation of test results.
