Red Lion Controls' DT800000 Ditak 8 Adjustable Time Base Tachometer is a compact digital tachometer that displays rotational speed or frequency on a 5-digit LCD. It includes a 3.6V battery for memory retention and weighs about 0.35 lb. The unit operates from 28 V DC and accepts either logic or voltage input signals, with an adjustable timebase to suit different pulse-rate ranges, and it is housed in a high-impact plastic case with a clear viewing window. Some listings note a maximum counting frequency of 10 Hz, and the product is listed as discontinued by the manufacturer.
