The HT Series of handheld tachometers from Ono Sokki are lightweight and compact digital tachometers that are available is both contact and non-contact variants. The HT-3200 in a contact-type tachometer offers a low measurement range that starts from 0.5r/min, and the HT4200 is a non-contact instrument that allows measurements to be taken from multiple measurement marks on at low rotation speeds. 

Ono Sokki is one of the world's leading manufacturers of this type of instrument and Eurolec are the UK and Ireland's sole distributor of their products.
