Ratemeter
Product Code : LSK-PL-10300
Ratemeter (SKU LSK-PL-10300) is a battery-operated, portable Geiger counter (GM counter) with a built-in Geiger-Müller tube that responds to alpha, beta and gamma radiation. Developed especially for education, it suits radioactivity lessons in the lab and background-radiation surveys in the field for senior school and college physics. Science Lab Supplies supplies it from Ambala, India to schools, colleges, training institutes, tender contractors and distributors.
Specifications
The ratemeter houses its GM tube inside the case and runs on batteries, so no separate detector or mains supply is needed. It displays readings in counts per second (CPS) and dose rate in µSv/h, with maximum, minimum and average views, and offers eight fixed count periods from 1 to 100 seconds.

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.
- B.Sc. nuclear physics: counting statistics and absorption of radiation by materials.
- Teacher demonstrations with sealed school sources.
Radioactive sources are hazardous and are not part of this item. 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. Radioactive sources are not included. The quotation states the batteries and any accessories offered, and a stopwatch or scaler for timed work can be added.
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). Contact the team through the contact page, use the enquiry cart, or follow the lab tender page for tenders.
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.
Does it come with a radioactive source?
No. Sources are not included. Any sealed source must be obtained, stored and handled under your institution's rules and national regulations, with teacher supervision.
Who supplies the Ratemeter?
Science Lab Supplies supplies it from Ambala, India, as part of its physics range, and quotes it 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.
