|
| The 440RF/D is a highly sensitive, low energy, RF shielded survey meter suited for fast, accurate measurements of background and other low radiation levels. Survey meter design is based on the latest CMOS microprocessor technology. The 440RF/D has EIA approval and is designed to meet the radiation sensitivity and measurement geometry requirements for television receivers set forth by the U.S. Department of HEW. 21 CFR 1020.10 requires "Radiation exposure rates produced by a television receiver shall not exceed 0.5 milliroentgens per hour at a distance of five (5) centimeters from any point on the external surface of the receiver," as measured in accordance with this section. Features Meets 21 CFR 1020.10 Television Receiver and 21 CFR 1020.40 Cabinet X-ray Systems require-ments for radiation surveys Insensitive to 20 mW/cm2 RF fields Resolves 0.02 mR/h from 15 kilovolt X-rays Auto-zeroing New CMOS design for stability and performance Batteries accessible from outside instrument Available in SI unit |
