The Monitor 4EC Radiation Alert offers a more linear reading for gamma and x-rays (above 40keV). Features a new ergonomic design, this product is a compact, general purpose survey meter capable of detecting alpha, beta, gamma, and x-rays over 3 selectable ranges. A red count light flashes and a beep sounds with each event detected.
As with the Monitor 4, this product has a halogen-quenched GM tube but also has an energy compensated sidewall 2mm tin filter. Thin mica window 1.5-2.0 mg/cm2 thick.
Analog Meter holds full scale in fields as high as 100X maximum reading.
The Monitor 4EC can detect alpha down to 2.5 MeV; typical detection efficiency at 3.6 MeV > 80%. Detects beta at 50 keV with 35% efficiency. Detects beta at 150 keV with 75% efficiency. Detects gamma and x-rays through the detector sidewall is flat within +61% or -26% over the range of 40 keV to 100 keV, and within +35% or -17% over the range of 100 keV to 1.3 MeV. Normal background is approximately 10-20 CPM. 1000 CPM/mR/hr (referenced to Cs-137)
Operating Range:
0-.5, 0-5, 0-50 mR/hr
0-500, 0-5,000, 0-50,000 CPM or 0-500 µSv/hr
0-50 mR/hr.
Range Switch: X1, X10, X100, Battery Check.
Accuracy: Typically ±15% of reading (referenced to Cs-137)
Audio: Internally mounted beeper (can be turned off for silent operation).
Power Requirements: 9-volt alkaline battery up to 2,000 hrs at normal background
Temperature Range: -20° C to 55° C (-4° F to 131° F).
Weight: 245.7 grams (8.7 oz) without battery
Outputs: 3.5 mm headphone jack with pulse out.
Size: 210 x 70 x 48 mm (8.25 x 2.75 x 1.875 in.)
The Monitor 4EC Radiation Alert is supplied with a carrying case, a mini-B 5 pin and 1 x 9V battery. A USB option is available upon request as a USB Cable is not included. There is also a SI Meter option available.
