Test Kit Twin Check 4.0

Test Kit Twin Check 4.0

Electronic test for water-in-oil and BN (Base Number).

Product description

Applications

TEST KIT TWIN CHECK 4.0 optimises the measuring processes and facilitates easy monitoring of trends in the condition of lubricating and hydraulic oil.
The collected data of water-in-oil and alkalinity reserve (BN, formerly TBN) measurements gets recorded and stored on an internal memory chip with large capacity. Due to the required setting of date, time and the name of the measurable parameter prior to starting the test, it is possible to easily check whether the test procedures have been actually conducted. This enables avoidance of any inaccuracies or falsifications of test results. Besides, owing to the automatic data recording and storing, there is no necessity to manually additionally document the obtained corresponding values. Through the USB to serial connection the test results can be quickly imported into a terminal program and further into Excel for plotting of a graph which portrays the trend in the oil condition (see graph below).

Parameters to measure

Water in oil:

  • Measuring range: 0 – 1.0 vol. % H2O
  • Measuring time: depends on the measured value (max. 20 min.)
  • Accuracy: ± 3%

Base Number:

  • Measuring range: 0 – 100 BN
  • Measuring time: depends on the measured value (max. 20 min.)
  • Accuracy: ± 1 BN

Parts replacement

The essential distinctive feature of the TWIN CHECK 4.0 is the possibility to replace every single constituent part (no matter plugged or screwed) in case of malfunction or damage occurred. Therefore, engineers and users are provided with an advanced cost-effective option previously not available on the market. After short on-site technical diagnosis and determination of malfunction cause (employing, for example, the TEST KIT VERIFYER for detection of pressure related problems) the required component can be ordered and independently replaced.

Directions for use

The content of water in oil and alkalinity reserve is defined in the identical test procedure. The two chambers of the reaction vessel of the TWIN CHECK 4.0 get filled with the oil sample and the reagent. After closing the device, the integrated pressure sensor adopts the external (ambient) pressure as a measurement line with a zero-referenced value.
Once the procedure is completed, by shaking the test device every two minutes for 15 seconds the measuring process takes place. The pressure build-up is directly proportional to the water/BN present in the oil under examination. As soon as the pressure is no more increasing (i.e. the water/BN parameter is constant), the TWIN CHECK 4.0 automatically stops measuring and displays the end result. Therefore, the amount of time required for testing varies in accordance with the measured water-in-oil/BN value. So, for instance if no water in oil is detected within the first two minutes of the measuring process, the test result will be automatically shown on the electronic display of the test unit. With regard to the BN test, it is necessary to conduct a single time calibration for each oil grade of the engine system (corresponds to the BN modes available) prior to proceeding with measurements of the alkalinity reserve.
