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. Science Lab Supplies supplies the instrument from Ambala, India, and quotes it for schools, colleges, training institutes, tender contractors and distributors.
Specifications
A 6-digit bright green LED display counts up to 999,999 counts or seconds. Counting can be manual or timed over 1, 10 or 100 seconds, and a press-to-read switch shows the voltage applied to the GM tube (300 V to 500 V). A built-in 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 covers both uses.
- 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.
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 listed on the quotation. The specification does not list a GM tube, light gates or radioactive sources among the contents, 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. Tender buyers should look at the lab tender page; other enquiries go through the contact page or the enquiry cart.
