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 suits accelerated-motion practicals in Class 9 and 11 physics and in first-year college mechanics. Science Lab Supplies manufactures the apparatus at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and its factory quotes schools, colleges, tender contractors and distributors without an agent.
Specifications
Track, sensors, timer, base and supplied items of this photogate apparatus each have a row below. In short, a 480 mm high, 30 mm diameter track carries four photogates on a stable base with a graduated inclination angle, and the timer stores its data and shows the ball's passage time for each of three intervals.

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 electronic lab instruments in India and abroad.
- Class 9 science: uniform and non-uniform motion, distance–time and velocity–time graphs, with hand timings on School Digital Stopwatches for comparison.
- Class 11 physics: uniformly accelerated motion and the equations of motion.
- Acceleration on an inclined plane as a function of angle, followed by launches at set angles on the Projectile Launcher.
- 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.
Packing, MOQ and Lead Time
We can quote a single apparatus for demonstration or several for student groups. The quotation states packing, delivery time and price for the quantity you name, and other inclined-plane, free-fall or timing items for the same mechanics lab can be quoted together.
Holding an Importer-Exporter Code, Science Lab Supplies is a registered exporter that can ship to buyers in Tanzania, Uganda, the UAE, Saudi Arabia, Oman and the Philippines. A count of the timers your motion practicals need can be sent through the contact page or the enquiry cart, and mechanics lab equipment in India tenders are covered by the lab tender page.
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, which the timer displays and stores.
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?
Assembly of this timer apparatus takes place at the Science Lab Supplies factory in Saha, Ambala, India, where the company manufactures it, and your quotation is issued there rather than by an agent.
Are instructions for experiments supplied?
Yes. Methodological and experimental guidance describing real experiments comes with the apparatus, covering runs of the ball down the 480 mm track at different angles set on the graduated base, with the timer showing three interval times.
