Yuyutsu Instrument Company started its R&D in Coating Thickness Gauges (Eddy Current Type) in 1992. In 1994 it sold its 1st machine. Later, R&D work in Coating Thickness Gauge Magnetic type started and soon the Magnetic model also entered the market.
In 2013, R&D in Hall Effect Thickness Gauge was completed and reached the market. Parallelly, a continuous improvement and feature addition process was going on in earlier machines.
Later, Yuyutsu started manufacturing a Distillation Analyzer, a Flash Point Tester, an Ultrasonic Thickness Gauge, a Bresle Salt Tester, a handy pocket-size Bluetooth coating thickness gauge (both magnetic and eddy current), and a low-voltage holiday detector.
