The Water Separation Index Meter Consumable Pack 840-99-5944 is a dedicated consumable pack for the American EMCEE 1140 Aviation Fuel Water Separation Index Tester. Below is its detailed introduction:

Product Specifications

Packaging Specifications: Each box contains 6 test packs, with each pack including 6 syringes, pipette tips, coalescing filters, and glass tubes for turbidity testing.

Testing Method: Each vacuum-sealed test pack is used to complete a single test. Each coalescing filter indicates the type of fuel and the applicable ASTM method. Each test pack also includes a distilled water container for water separation index testing.

Testing Principle

Water Separation Characteristics Determination: Testing is conducted using a turbidimeter, mechanical stirrer, and filter. A portion of the sample is placed in a clean straight-neck flask, and the turbidimeter is adjusted to a value of 100 before discarding this sample and retaining the flask. Another portion of the sample in a plastic syringe is emulsified into an oil-water mixture using the stirrer, then passed through the filter in a specified manner, with the filtrate collected in the previously retained flask. Based on the amount of residual water, a transmittance value is obtained using the turbidimeter. The transmittance value can be expressed as MSEP-A or MSEP-B, and the final test result is reported as the nearest integer between 50 and 100. A higher value indicates that the fuel's water is more easily coalesced, meaning the fuel contains fewer surface-active substances.

Cleanliness Test: At a certain rate, a portion of the fuel sample is filtered through a coalescing filter, and the filtrate is collected in a straight-neck flask. The flask is then placed in the turbidimeter, and the turbidimeter is adjusted to a value of 100 as a reference standard. This portion of the processed sample is discarded, and another portion of the untreated sample is poured into the same flask and placed back into the turbidimeter. The value can be expressed as MSEP-C&B, and the final test result is reported as the nearest integer between 50 and 100. A higher value indicates a relatively low free water content in the fuel.

Product Features

Convenience: One box contains 6 sets of testing tools, enabling 6 tests, reducing test preparation and cleaning time, and ensuring high cleanliness to avoid adverse effects.

Automatic Timing: Due to the semi-automation of various tests, operator skill requirements and human errors are significantly reduced. This portable water separation index meter can preset and control emulsification cycles, coalescence time, settling time, turbidity adjustment time, and final test time.

Portability: The Model 1140 Portable Water Separation Index Meter has a net weight of only 26 pounds (shipping weight 42 pounds), housed in a sturdy aluminum case for easy carrying. The foam padding inside the case provides excellent protection.

Universal Power Supply: The Model 1140 Portable Water Separation Index Meter operates on a universal power supply (110/220V, 50/60Hz) or an internal rechargeable battery pack. After 25 tests, the internal rechargeable battery pack requires priority charging.

Economy: Simple operation, short time consumption (5–10 minutes), low sample consumption (150 mL fuel sample), and high efficiency.
