The company’s DIGI cell technology to monitor oil condition in the marine sector was introduced in 1993. The DIGI Plus combined test cell, the latest innovation in the range, enables operators to test for water in oil and for the base number of oil samples. It also will help users to detect out-of-spec oils and lubricants and identify potential problems before they become critical, according to Parker Hannifin.
The DIGI Plus has a built-in test memory for recording up to 50 individual test results as part of a pre-programmed test plan, whilst also having the capability for miscellaneous or spot tests as well. Test results are downloaded using a USB cable and the downloaded data can then be used as part of a trend analysis programme. The USB cable can also be used for battery charging of the DIGI Plus cell.
Having been developed for use in challenging conditions, the DIGI Plus features an improved backlit colour display that aims to provide better visibility, especially in poor light conditions. The colour display has been designed to simplify identification of alarm conditions and pass or fail results, while also guiding the user through important test steps such as cell cleaning. The cell has been constructed from lightweight glass reinforced plastic with non-slip twist grips and aims to reduce handling fatigue during testing.
The DIGI Plus combined test cell offers both water in oil (H2O) and base number (BN) testing and comes as part of Parker’s DIGI Plus Field Test Kit, which also incorporates three other test measurements: acid number; insoluble loading and basic viscosity.
