Intermediate Nuclear Lab System

Intermediate Nuclear Lab System



The Intermediate GM System lets your students perform more in-depth experiments. Complete computer control of both data acquisition and the ST360 are available via the USB or serial ports. The software provided allows real time data collection with automatic transfer to a spreadsheet file. Since you have complete computer control of data collection rates as well as the Geiger-Mueller Counter, you can create your own experiments. Through the spreadsheet functions, you can analyze data, set up and plot graphs and print a hard copy of the screen. In addition, the computer screen displays of all the ST360 functions including analog emulation of the ratemeter mode.

Add To Cart


The TEL-ST360S Intermediate Lab System represents the latest technology in bench top nuclear counters. Offered as a direct replacement for the popular ST350, this instrument features many improvements and additions to enhance application and flexibility for Nuclear Science instruction, Nuclear Medicine and Health Physics training.

In addition to supporting many types of GM counters, the instrument now includes an internal preamplifier and improved high voltage supply to operate scintillation detectors as a gamma counter for wipe testing and other gross gamma measurements.

The ST360 will operate as a stand-alone bench top instrument or may be controlled by a PC or Macintosh computer for remote operation and data storage. Computer connectivity has been enhanced by the addition of a USB interface for Plug and Play operation. RS-232 serial outputs are still provided for connection to older computers without USB ports.

The STX software supplied with the ST360 Radiation Counter produces computer screen displays of all functions including analog emulation of the ratemeter mode. Real-time data is automatically transferred to the computer and stored in spreadsheet compatible files. Data analysis and graphical presentation is now possible using many common spreadsheet programs. Both PC and Macintosh software is included. The PC software operates on Window 95 and higher and the Macintosh software is compatible with System 7 through System 9. (Not all operating systems support USB).
