Sper Scientific 810032 Stopclock - Manual (Page 3)

Ruggedly design for prolonged use as both a
bench-top count-up timer and a stopclock.
Non-skid feet keep the unit firmly in place during
use, yet it is small and light enough to be easily
moved around the lab as needed. A large LCD
and buttons make it easy to operate. Counts-
up to 10 hours with 1/100th second resolution
in selectable cumulative or interval split modes.
Comes complete with one AA battery and two
cables for connection to an external trigger
such as a photo gate. This unit is CE approved
and available with NIST traceable certificate of
calibration (810032C).
