Ratemeter
Product Code : LSK-PL-10300
Ratemeter (SKU LSK-PL-10300) is a battery-operated, portable GM counter with a built-in Geiger-Müller tube that responds to alpha, beta and gamma radiation. Developed especially for education and ideal for field use, it suits radioactivity lessons in the lab and background-radiation surveys outdoors for senior school and college physics. Science Lab Supplies can quote the counter from Ambala, India, for schools, colleges, training institutes, tender contractors and distributors.
Specifications
Detector, units, count periods and power of the ratemeter each have their own row. In short, a built-in GM tube detects alpha, beta and gamma radiation, readings appear in CPS and in µSv/h with maximum, minimum and average views, eight fixed count periods run from 1 to 100 seconds, and batteries power the unit.

Applications and Experiments for the Ratemeter
The instrument counts ionising radiation so students can measure background radiation, compare readings near and away from sources, and see the random nature of decay in repeated counts. Fixed count periods make it simple to take and compare timed readings in a class practical.
- Class 12 physics: radioactivity and the nature of alpha, beta and gamma radiation.
- Background radiation surveys indoors and in the field.
- Inverse-square checks, with distances from a sealed source set against a Wooden Ruler 1 Metre.
- B.Sc. nuclear physics: counting statistics, cross-checked with a GM tube on a Scaler Timer.
Radioactive sources are hazardous. Use only sealed sources, under teacher supervision and within your institution’s radiation-safety rules.
Standard Scope of Supply
The Ratemeter is supplied as a single portable unit with its built-in GM tube. The quotation states the batteries and any accessories offered, and a stopwatch or a scaler for timed work can be added to the same quotation if your radioactivity bench needs one.
Packing, MOQ and Lead Time
Price one ratemeter for demonstrations or several so groups can work in parallel. The quotation you receive gives packing, delivery time and price for that number; related counting and timing items, or other school physics lab equipment in India, can be listed alongside.
Registered as an exporter with an Importer-Exporter Code, Science Lab Supplies is able to ship to buyers in Tanzania, Uganda, the UAE, Saudi Arabia, Oman and the Philippines. Science Lab Supplies is registered for GST (GSTIN 06ADEPJ0574F2ZU). Counters for a radioactivity bench can be priced after a note on the contact page, from items saved in the enquiry cart, or through the lab tender page.
Frequently Asked Questions
Which types of radiation does the Ratemeter detect?
Its built-in GM tube is sensitive to alpha, beta and gamma radiation, so it can be used across the standard school radioactivity experiments and for background surveys.
Does it need a radioactive source?
Not for background counts, which the built-in tube picks up on its own. Source experiments need a sealed source obtained, stored and handled under your institution’s rules and national regulations, with teacher supervision.
Who supplies the Ratemeter?
This counter is offered by Science Lab Supplies in Ambala, India, as part of its physics range, and can be quoted with GM tubes, scalers or timers when a radioactivity bench is being set up.
What count periods are available?
Eight fixed count periods: 1, 10, 20, 30, 40, 50, 60 or 100 seconds. Readings can be viewed as maximum, minimum or average in µSv/h and CPS.
