Electronic Timer with Photogates
Product Code : SCL-PL-12346
Electronic Timer with Photogates (SKU SCL-PL-12346) is an inclined-plane motion apparatus: a ball rolls down a cylindrical track fitted with four optical sensors, and an electronic timer records its passage times over three intervals. It is used for accelerated-motion practicals in Class 9 and 11 physics and in first-year college mechanics. The apparatus is made by Science Lab Supplies at its Saha, Ambala factory (Plot 448, HSIIDC Industrial Area, India) and sold direct to schools, colleges, tender contractors and distributors.
Specifications
The track assembly is 480 mm high and 30 mm in diameter and carries four photogates. It sits on a stable base with a graduated inclination angle, so the slope can be set and read. The timer stores its data and displays the ball's passage time for each of the three intervals between gates.

Applications and Experiments for the Electronic Timer with Photogates
Three consecutive interval times from one run show directly that a ball rolling down a slope covers each section faster than the last. Changing the incline angle on the graduated base lets students relate acceleration to slope, echoing Galileo's inclined-plane experiments with modern timing.
- Class 9 science: uniform and non-uniform motion, distance–time and velocity–time graphs.
- Class 11 physics: uniformly accelerated motion and the equations of motion.
- Acceleration on an inclined plane as a function of angle.
- First-year B.Sc. and diploma mechanics: timing and graphing exercises.
Standard Scope of Supply
Each apparatus includes the track assembly with four optical sensors, the electronic timer with data storage, the base with graduated inclination angle, one ball and a power supply, together with methodological guidance describing real experiments to run. Anything optional you add is listed on the quotation.

Frequently Asked Questions
How many photogates does the Electronic Timer with Photogates have?
Four optical sensors are fitted along the 480 mm track, giving three timed intervals for each run of the ball.
Can the slope of the track be changed?
Yes. The base has a graduated inclination angle, so the track can be set to different angles and the angle read off for each run.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies manufactures it. Assembly takes place at its own factory in Saha, Ambala, India, and your quotation is issued there, not by an agent.
Are instructions for experiments supplied?
Yes. Methodological and experimental guidance describing real experiments comes with the apparatus.
