The Ludlum Model 9DP Series pressurized ion chamber meter provides highly sensitive measurements of exposure and exposure rate. It can simultaneously display the exposure rate and integrated value, or the highest rate seen by the instrument. Contact us for the HAZMAT Series that provides ICRU-Based Ambient Dose Measurements.
The Model 9-4 & 9-3 uses rugged air ionisation chamber for performing beta-gamma dose rate measurements over a five-decade spanning over a wide radiation range. The chamber wall (including the instrument case) is 1000 mg/cm2. A 1000 mg/cm2 retractable beta shield allows beta measurement with a 7 mg/cm2 window.
The Ludlum Model 9-7 Ion Chamber Display Unit is a digital readout and control unit that can be attached to any compatible ion chamber (sold separately). This instrument provides remote monitoring in high-range beta and gamma fields.
