Spectro Scientific, a suppliers of oil, fuel, and processed water analysis instrumentation and software, 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, bio-diesel, gas-ethanol and DEF” has also been granted in Australia.
The CoolCheck 2TM 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.
