ST 90 is an indigenously developed digital Tachometer designed to work in tough industrial environments. Efficiently monitors engines in Diesel gensets or engine only applications for measuring the RPM. ST-90 takes input from Charging Alternator pulse or through Magnetic pick up. Provided with user configurable keys, ST 90 exhibits engine RPM, run hours in clear backlit LCD display. Also has the ability to monitor and display battery voltage. Sun Smart Tacho meter has undergone type test as per IEC 60068 series.
