Reaction Timer
Reaction Timer (Product Code: SLE/BL/049) is a classroom timing instrument used to measure how quickly a person responds to a stimulus in biology, physiology and physical education lessons. Students use it to record their response time to various stimuli, including light, sound and touch, and then compare how fast each sense triggers a reaction. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, among its biology teaching aids for schools and colleges.

What Is the Reaction Timer Used For?
Students usually work in pairs: one person runs the test while the other waits to respond as soon as they notice the signal. After several trials with a light, then a sound, then a touch stimulus, the class can calculate an average for each and ask which sense produces the quickest response. The same routine can compare the dominant and non-dominant hand, test the effect of a distraction, or look at results before and after a short spell of exercise.
The data lead naturally into a discussion of how a signal travels from a sense organ to the brain and out to a muscle, and why a reflex is faster than a decision. Because results differ so clearly between people, the timer also makes a good starting point for a science fair project kit in India on attention, practice or fatigue. Ask students to keep conditions the same between trials — same seat, same hand, same warning — so their comparisons are fair.
Supplier
The Reaction Timer is supplied by Jain Scientific Equipments Private Limited, trading as ScienceLab and located in Ambala, Haryana, India. The company equips teaching laboratories in India and international markets, and a department can order the timer with the sense-organ and physiology items used in the same unit on one quotation.

Frequently Asked Questions
Which stimuli can the Reaction Timer test?
The Reaction Timer measures a student's response time to various stimuli, including light, sound and touch. Running the same test with each stimulus lets a class compare which sense produces the quickest reaction and discuss why the results differ.
What display and power supply does the Reaction Timer use?
Display type and power supply for the Reaction Timer are not given in our current product information. Please ask through the contact page and we will share the datasheet for the model we quote before you place an order.
What age group is the Reaction Timer suitable for?
The Reaction Timer suits reaction-time activities from middle school to college. Younger classes can simply compare light, sound and touch responses, while senior students calculate averages, repeat trials and discuss nerve pathways and reflex arcs using the same data.
How should the Reaction Timer be looked after?
Keep the Reaction Timer on a dry bench away from water and chemicals, avoid dropping it, and store it in a cupboard between lessons. Check that it works before a practical so each pair of students can start testing straight away.
Is a calibration certificate available for the Reaction Timer?
If your department needs timing documentation for the Reaction Timer, mention it in your enquiry. We will discuss with you what can be provided for the specific unit quoted before you commit to the order.
Who supplies the Reaction Timer?
The Reaction Timer is supplied by Jain Scientific Equipments Private Limited, which trades as ScienceLab from Ambala, Haryana, India. Schools, colleges and distributors in India and international markets can ask for one unit or several timers for a whole class.
