Product Description

ASTM D7097
Thermo-oxidation Engine Oil Simulation Tester TEOST MHT Piston Deposits Tester

Product Description

 

In the MHT test, 10 mL of sample oil is continuously passed over a pre-weighed steel Depositor Rod for 24 hours at 285°C. The increase in rod weight caused by deposits is used as a measure of oil performance.

Now known as ASTM D7097, the MHT® Protocol was incorporated in ILSAC GF-3 and GF-4 as well as API SL and SM categories.

The Chrysler/Tannas TEOST test has become an alternative to using large, relatively variable, expensive and time-consuming engine test stands.
 

The instrument is used for the thermal oxidation simulation test of engine oil. The mixture of the sample and catalyst is fully mixed evenly, and a quantitative amount of air is introduced. The sample flows down the metal coil on the deposition rod, and circulates for 24 hours. Deposit bars to evaluate the tendency of engine oils to form deposits under high temperature oxidizing conditions.

Reference Standards

4.SH/T0750 "Determination Method of High Temperature Oxidation Deposits of Engine Oil (Thermal Oxidation Simulation Test Method)".

Main Technical Features

 

1.The instrument can replace the similar foreign TEOST.
2.The main components are imported from abroad,including the temperature controller, deposition rod, gear pump, flow sensor, etc.
3.The working time of the instrument can be set, and it will stop automatically after the test.
4.The instrument can be tested by ASTM D6335, SH/T0750 method through additional components.
5.The instrument is equipped with a catalyst magnetic mixing device, which can set the mixing time and mixing speed.
6.Automatic electronic flow controller, accurately control the gas flow rate of 10ml±0.2ml/min.
7.All parameter settings can be performed on the touch screen, and the test can be started with one key after completion.
