Tannas Instrument Company

Instruments For Testing Automotive Lubricants

Tannas instruments have been designed to answer particular needs expressed by oil companies, OEMs and additive manufacturers for measuring properties critical to high quality lubricants.  All instruments manufactured by Tannas are laboratory tested and certified prior to delivery to our customers.  On-site installation and customer training is provided with each instrument and is conducted by a Tannas Certified Engineer. Many of our patented bench instruments are required for meeting several international specifications for lubricant testing.

Rotating Pressure Vessel Oxidation Test (RPVOT); Quantum™ Method

This non-liquid 'dry cylinder' D2272, RPVOT apparatus is the first innovative approach to the test in decades -- eliminates the mess and dangers of hot oil baths and reduces the number of parts for quick turn around and interchangeability between methods.  Small, single-test, design permits multiple units to function independently dramatically increasing productivity.   For product brochure click here

Scanning Brookfield Test (Gelation Index)

Determines whether and to what degree the oil in the sump will flow in adequate quantities to the oil pump.  The lower the temperature at which this test reaches a critical value of viscosity, the more satisfactory the oil.  Gelation Index is a measure of the severity of engine oil gelation at low temperature.   For product brochure click here.

Tannas Foam Air Bath

Single bench-top air bath for running all four required foaming sequences (Sequence I, II, III of ASTM D892, and Sequence IV of D6082).  A safe, efficient alternative to oil baths.   For product brochure click here.

TEOST

A required test for passenger car engine oils (ILSAC GF-2, GF-3 and GF-4).  Simulates the high-temperature mix of engine oil and combustion gases and measures the resistance an oil has to forming deposits.     For product brochure click here.

Selby Noack Volatility Tester

A high-tech replacement for Noack equipment used to measure evaporation loss of lubricating oils without hazardous Woods metal heating and permitting collection of the volatilized material for further analysis.  Only instrument capable of generating values for new Phosphorous Emission Index for passenger motor oils and Sulfur Emission Index for diesel engine oils.     For product brochure click here.

Tannas Basic Rotary Viscometer

Broad Range Of Petroleum Test Products

Featured Products

Cold Filter Plugging Point; (CFPP)

• The Automated Cold Filter Plugging Point Analyzer fully conforms to method ASTM D6371 & IP-309. The vacuum is controlled by a dip tube immersed in a water filled jar just as specified by the method.
• The vacuum is automatically applied at every degree as the sample cools and its aspiration and release time are recorded and plotted. Fiber optic light guides are used at the bottom and top of the pipette that detect the start of aspiration and its completion. The result is reported when the aspiration or release times exceed 60 seconds.
• A wide range of models is available with working temperature ranges from ambient to -70°C.

Automated Rust Prevention Characteristics Bath

The Lawler Model 397 series Rust Baths are specially designed to run ASTM D665 and NACE TM0172. There is provision for conditioning and testing four or six test samples.  A micro controller based system controls temperature precisely to +/- 0.2'C. This system further controls all the automatic features as described below.

The test specimens are automatically lowered into samples at trigger temperature.  At the appropriate time the water dose is injected into the test sample automatically. At the end of the pre-determined test time the test rods from the sample are automatically raised. Thus there is no operator involvement during duration of the test.

The sample stirrers may be lifted up to enable easy removal of the sample beakers.  Time and temperature parameters and other operator interaction are performed through a highly intuitive touch panel.  A high temperature limit and a float switch is provided for safety.

Lemis Portable Density and Viscosity Testers

DM-300 Portable Density Meter

The operating principle is resonant method (vibration element) of measurement. It is based on the changing of frequency characteristics of the sensitive unit and resistance of the built-in temperature sensor in dependence of characteristics of the measured liquid.

Resonant tube technology implemented in DM-300 density meter achieves higher accuracy and stability of the measurements.  Design of the device considerably simplifies sampling and sample preparing procedure. 

Operator does not need any plastic syringes and other special laboratory glassware! Measuring chamber is especially designed for very viscous liquids. Cleaning procedure is shortened for more than 2 times comparing to similar class devices!

Portable Density Meters For LPG and LNG

Unique Laboratory Density Meter is a new development especially for liquefied petroleum gases (LPG) measuring.  It is based on the resonant method of density measurement and uses a small sample volume.  Obtained results are instantly converted to relative density (15ºC or 20ºC or 60º) in accordance with ASTM D1250 Tables.  Reading on the LCD facilitate measuring process and eliminate potential human error.
