Scaler Timer
Product Code : LSK-PL-10329
Scaler Timer (SKU LSK-PL-10329) is a general-purpose scaler-timer that counts pulses from a Geiger-Müller (GM) tube for radioactivity experiments and also works as a millisecond digital timer with manual or electronic triggering. It serves Class 12 nuclear physics topics and B.Sc. nuclear physics labs. Colleges, schools, training institutes, tender contractors and distributors can have it priced by Science Lab Supplies, a physics instruments supplier in India based in Ambala.
Specifications
Display, counting modes, GM voltage, power and size of the scaler-timer are listed in full below. In short, a 6-digit bright green LED display reaches 999,999 counts or seconds, counting is manual or timed over 1, 10 or 100 seconds, a press-to-read switch shows the 300–500 V tube voltage, and a loudspeaker gives audible counts.

Applications and Experiments for the Scaler Timer
With a GM tube connected, the scaler records counts over a fixed period for studying radioactive emission; with light gates or manual switching it times events to the millisecond. One instrument therefore covers both counting and timing work in the physics lab.
- B.Sc. nuclear physics: plotting the GM tube characteristic to find its plateau voltage.
- Measuring background count before source experiments.
- Class 12 nuclei topic: showing the random nature of radioactive decay with repeated counts.
- Mechanics: timing a falling object between light gates to find g, after a first look at falling spheres on the Apparatus for Demonstrating the Free Fall of Bodies, and comparing with an Analog Timing Experiment Clock.
The GM tube supply reaches 500 V and radioactive sources are regulated; operate the instrument under the supervision of a qualified teacher and follow your institution's radiation-safety rules.
Standard Scope of Supply
The Scaler Timer is supplied as a single unit as described above; any optional accessories are named on the quotation. A GM tube, light gates or other counting items can be added to the same quotation, so confirm the items you need on your enquiry.
Packing, MOQ and Lead Time
You can ask for a quotation for a single scaler-timer or several for a nuclear physics lab; each quotation gives the packing, delivery time and price for that quantity. A GM tube and ratemeter can be added so the counting setup is priced together.
Science Lab Supplies, a registered exporter holding an Importer-Exporter Code, can ship to buyers in Bangladesh, Zambia, Rwanda, South Africa, Qatar and Sri Lanka. Counting and timing set-ups can be described on the contact page or assembled in the enquiry cart; a college tender is handled via the lab tender page.
Frequently Asked Questions
What can the Scaler Timer be used for?
It counts pulses from a GM tube for radioactivity experiments, and it works as a millisecond digital timer triggered manually or by light gates, so one unit serves both benches.
What counting periods are available?
Counting can be manual or timed over 1, 10 or 100 seconds, with a capacity of 999,999 counts or seconds on the 6-digit display for repeated readings.
Who supplies the Scaler Timer?
Nuclear physics labs can get this scaler-timer quoted by Science Lab Supplies in Ambala, India, which arranges the packing and dispatch and can add a GM tube or ratemeter to the same order.
What power supply does it need?
The input power is 230 V ±5%, 50 Hz, protected by a 315 mA slow-blow fuse. Connect it only to a mains supply within that range.
