“It takes photographs, video clips, time lapse, operates as a webcam, and has a measurement
feature. It is so easy to use that my four-year-olds mastered it in one day! It is durable, and the price is right. I leave it out and the students are able to use it independently. I have other technological tools, such as iPads, [a] projector, [an iPod] Nano, flip cameras, and digital cameras—but my
favorite … tool is the SmartScope!” by

"The lighting is good, and the magnification is excellent. The picture is very clear on my computer screen." by
Leanne -- New Hampshire
"The smartscope is AMAZING. I love using it on the computer to really analzye objects/specimens, and my students really enjoy seeing the images magnified. Thank you." by

"The Smart scope is working great!! My kindergarteners LOVE it!" by
Karen -- Ohio
"I apologize..... :)
I totally doubted these microscopes when I got the email and thought "whatever! They're going to sit in the closet like the other ones because they'll be too hard to use.."
I was totally wrong....they ARE super EASY! :)" -- Library Media Specialist by

Product Code: 3265
Housed in a robust casing this self-contained sensor detects radiation from Alpha, Beta and Gamma particles.
The Geiger Muller sensor is very simple to use, as it does not require an external power source, deriving its power from the datalogger unit.

Half life Random events
Radioactivity exposure due to natural radon
Range 1 Counts per second: 0 - 10,000 cps

Range 3 Pulse Output 10 - 100%
The Geiger Muller Counter is supplied with a steel rod for fixing to a clamp (ring) stand. It is equipped with a built-in GM tube and integral high tension power supply.
A yellow LED power indicator shows that an operating voltage is supplied to the Counter, and a buzzer that emits an audible signal for each radioactive pulse that is recorded. The GM tube's window is made of a very thin and delicate material, which is easily destroyed. For this reason it has been equipped with a protective cap that may be left on except when measuring Alpha radiation.
Technical specification for the GM Tube window:
Thickness: 1.5 to 2.0 mg/cm2
Useful diameter: 9.14mm
Gas filling: Neon, Argon, and Halogen
Use the Counts per second range for investigations to determine half life and absorption of radiation by different materials.
Use Open Count for recording background count. Pressing the button on the sensor housing starts the count. Pressing the button again, hold for a second and release, resets the count to zero.
Pulse Output - Each radioactive particle will generate one voltage pulse. The occurrence of the pulse is recorded to show the randomness of atomic decay. This range requires fast data capture.
Measurement procedure: Radioactive sources used in schools are usually weak, but care must be taken in handling them. An authorised person must be in attendance. Ensure all local rules and recommendations made in any relevant Safety Data Sheets are complied with. Prepare a risk assessment before the experiment or activity is carried out.
