Octane and Hexadecane Value Tester TP-131

  • TP-131



Product Description

Product Description

TP-131 octane and cetane value tester is the latest generation of the octane and cetane measuring instrument, in line with ASTM D2699-86, ASTM D2700-86. It adopts international advanced measurement principle, designed in accordance with the diversity of domestic oil, filled the gap of detecting many kinds of oil. TP131 is more precise and quick in the detection of oil octane and cetane value, with English language digital display and big data storage volume. It can directly print the test values, with user-friendly page design, simple operation, imported shell and chip, alloy fully sealed design, long standby cycle charging. It is much suitable for service in working sites, outdoors and laboratories.


Technical characteristics

1.TP-131 can check gasoline octane and diesel cetane value at the same time, dual functions into one.

2.After long-term data collection, database completion, new technologies integration and multiple detection modes, it can detect many kinds of oil such as mathanol gasoline, ethanol gasoline, naphtha, solvent oil, straight-run oil, light oil, aromatics, MTBE, manganese-based, mathanol diesel, catalytic diesel, biodiesel, emulsified diesel etc, filled the gaps in detection for those oil products.

3.Desktop structure, stainless steel countertop, simple design, beautiful appearance, convenient use, complete accessories. Introduced the international dielectric content measurement principle.

4.Fast and accurate detection, simple operation, large screen display with EL backlight support convenient for use in dark environment, menu operation of host panel.

5.Imported Germany instrument shell, durable, small and easy to carry. Chips and core components are imported with instrument sensitivity and service life increased. Alloy metal fully sealed sensor, packing box with high strength, high impact resistance, waterproof, damp-proof, dust-proof, enclosing square sponge.

6.Can pre-set the mode upper and lower limits, automatic display of beyond the scope, convenient for user’s testing needs.

7.Energy saving function of automatic shutdown, with low power consumption design, 4 rechargeable batteries, cycle charging available, higher battery reliability.
