TEL ST250 Ratemeter
- Battery powered
- Rugged construction
- CPS and CPM scales
- Interchangeable GM probes
- Data-Link to IBM-PC
- Emulation software
- Spreadsheet data files
The ST250 Ratemeter introduces new concepts to a basic nuclear radiation instrument. Battery operated (up to 8 hours with the internal rechargeable batteries), an AC line power charger and a Data Link with software to provide a direct connection to IBM-PC compatibles means the unit is extremely flexible. The ST250 can be used for radiation surveying, Nuclear Science Instruction or for Health Physics Training. Up to 150,000 cpm, a variable, fully regulated high voltage output of 0-1200VDC for GM tubes, and a large easy to read meter with dual scales makes the ST250 a world class instrument.
