Thermal properties analyser.

There’s never been a thermal properties analyzer that gives accurate measurements under all conditions.

Small sensors are fragile and face contact resistance. Large sensors and high-priced, steady-state methods, require long heat times, which drive moisture away from the sensor and alter the reading. Alternative instruments use one standard equation without making any adjustments for real-world conditions—plus they’re bulky and expensive. There’s simply been no convenient or affordable way to measure accurately. Until now.
