0.0001 s accuracy Measures periods Stores time data

The Six-Digit readout with a resolution of 0.0001 s using a 40 kHz ± 0.02% quartz crystal. Operating with one or two Photogates, it measures the interruption of a single Photogate or the time between breaking a pair of Gates.

In the Memory Mode, it times two interruptions of a single Gate and store the results.

In the Period Mode, the time between the first and third break of a Photogate is recorded.

The Electronic Stop Clock is line powered, a more expensive way to build things, but we think it is worth it. There is no ac adapter to lose or batteries to replace just before the lab starts.

ET-38 Basic Timer

The best Timer value on the market with .001 s intervals, bright LED digits and a full size Photogate that is included. There is no ac adapter to lose either, since it is line powered. Timing precision in all your experiments is what you get, and at the best price ever.
