Geiger Counter
Geiger Counter (Product Code: SLE/PHY/119) is a compact, general-purpose radiation survey meter used to detect alpha, beta, gamma and X-radiation in school and college nuclear physics practicals. Physics teachers use it to make radioactive decay visible and audible, because a red count light flashes and a beep sounds with every event it detects across its 3 selectable ranges. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as part of its nuclear physics lab equipment range.

What Is the Geiger Counter Used For?
In the physics laboratory the Geiger Counter is the quickest way to show students that ionising radiation can be detected and counted. A typical lesson starts by recording the background count in the room, then brings a sealed school source closer to show the count rising, and finally places sheets of paper, aluminium or lead between source and detector to compare how far alpha, beta and gamma radiation penetrate.
Because every detected event produces a flash and a beep, the meter also demonstrates that decay is random: students can listen to the irregular clicks and count them over fixed intervals. For any radiation experiment, keep sources in their storage containers when not in use, handle them with tongs, and follow your institution's radiation-safety rules.
Supplier
ScienceLab is the trading name of Jain Scientific Equipments Private Limited, an Ambala, Haryana company that supplies laboratory equipment to schools, colleges and institutions in India and international markets. The Geiger Counter is a sourced survey meter, and we can quote it together with the sealed sources, tube holder and scaler timer listed in our physics range.

Frequently Asked Questions
What radiation does the Geiger Counter detect?
The Geiger Counter (SLE/PHY/119) detects alpha, beta, gamma and X-rays over 3 selectable ranges. Its reading is more linear for gamma and X-rays above 40 keV, which suits classroom comparisons of different sources and absorbers.
How does the Geiger Counter show that radiation has been detected?
The Geiger Counter signals each detected event in two ways: a red count light flashes and a beep sounds. This lets a whole class see and hear individual counts during a demonstration, even from the back of the room.
Are radioactive sources included with the Geiger Counter?
No radioactive sources are listed as part of the Geiger Counter; the product is the survey meter itself. Sealed americium, strontium and cobalt sources appear as separate products, so name any sources you need in your quotation request.
Who supplies the Geiger Counter?
The Geiger Counter is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab) of Ambala, Haryana, India. The company sources this survey meter and delivers it with its wider physics range to schools, colleges and institutional buyers in India and international markets.
Is a calibration certificate available for the Geiger Counter?
Calibration paperwork for the Geiger Counter is not part of the standard listing, so please raise it before ordering. Tell us through the contact page what documentation your institution needs and we will confirm what can be provided.
What should I include when requesting a quote for the Geiger Counter?
For a Geiger Counter quotation, state the quantity, the delivery address or destination country, and whether you also need sealed sources, a GM tube holder or a scaler timer. Orders for several laboratories can be combined in one enquiry.
