Read MoreSend InquiryPocket smart timer with built-in photo gate can measure time, speed and acceleration . Microprocessor control offered 0.01% accuracy. 2 AA battery for 2 hours continuously working . Large internal Memo up to 20 data points can be recorded Direct reading acceleration result down an incline plane (need a 25mm ball which not included) more than just one timer. Link two timer with a special cable supplied to build up a 4 photo gates system in one second .
Read MoreSend InquirySpark Timer Accelerator is used for determining the rate of acceleration in a falling weight, calculating the speed of a moving art or studying the forces of friction. A paper tape is pulled through the timer while a spark at precise and same interval is created which burns tiny dots in the paper strip. The faster the strip passes through the timer the larger the distance between the dots. This allows you to calculate the acceleration.

Has two hands, one measuring seconds and the other minutes. Dual scale dial for minutes/seconds and hundredths of a minute. Operates on one 'AA' battery, not included. Can be easily seen from 15 feet(5m) away.
