Spectro Scientific awarded US and Australian patents for fuel measurement method

March 30, 2017 |

In Massachusetts, Spectro Scientific has been awarded U.S. patent 9,448,112 B2 for a method to measure two key vehicle fluids. The patent for “Multifunctional fluid meter and method for measuring coolant, biodiesel, gas-ethanol and DEF” has also been granted in Australia.

The CoolCheck 2 is a dual wavelength spectrometer specifically designed to test coolant and diesel exhaust fluid (DEF) without the use of chemical reagents or solvents. Specially designed sample cuvettes allow the analyzer to read in both the UV-visible and NIR range simultaneously. The measurement method provides eight key coolant parameters or two DEF parameters in less than one minute. A recently released calibration update improves the performance in measuring nitrites, a key coolant additive. This new method is able to analyze a wider range of coolants on the market today as well as new fluids when they are introduced.

The CoolCheck 2 measures the coolant or DEF directly from the vehicle and is designed to be easily operated by vehicle maintenance staff. The analyzer’s on-site analysis capability, speed and convenience eliminate the wait associated with outsourcing laboratory analyses and provide better accuracy than simple test strip methods. The CoolCheck 2 is a companion device to Spectro Scientific’s MicroLab automated on-site oil analyzer, which allows a mechanic to analyze all major vehicle fluids to diagnose the health of the equipment and identify potential problems.
