Ludlum Model 9DP hand meter, pressurized ion chamber for measuring gamma and X-ray radiation

New design, all digital, Ludlum Model 9DP hand meter, with pressurized ion chamber, provides sensitive exposure(rate) measurements of gamma and X-ray. The 9DP displays dose rate together with an integrate mode or peak holding to capture the highest reading, since the instrument was turned on. All logged data are written in csv format to a plugged-in industry standard, USB thumb drive for convenient retrieval by a spreadsheet or database program.

advantages

• big 3.5 inch screen (256 colors) makes distant reading possible
• sunlight readable color display
• USB port for datalogging via USB stick and adjusting parameter via keyboard
• pressurized ion chamber with quick air release function (for safe transportation)
• 2 units in one screen: rate combined with integrate or peak measurement

scope

For use in environments where precise rate/integrate is required, in example for:

• medical applications (radiation leak)
• laboratory applications (control)
• industrial applications (safety)

characteristics

• measurement of gamma and X-rays above 25 keV, beta above 1 MeV
• Sv/h units: 0-5 µSv/h, 0-50 µSv/h, 0-500 µSv/h, 0-5 mSv/h, 0-50 mSv/h
• response time: 5 seconds in lowest range to 2 seconds in highest range (10% to 90%).
• warm up time < 1 minute when instrument is equal to environment temperature
• chamber volume 230 cc pressurized to 8 atm (117 psi)
• minimum readout: 0.01 µSv/h
• accuracy: +/- 10%
• auto zeroing & ranging
• auto LCD backlighting
• rate, integrate & peak hold readouts
• data logging with time stamp
• USB connectivity
• alarm: sound and on screen
• rechargeable batteries for 12-30 hours per charge
