Radiation Alert® Analog Detectors
|
|
|
Easy setup and
readability
|
|
|
All
models are factory-calibrated to pulse generator and can be calibrated to
ANSI
|
|
|
standards by any certified lab. Anti-saturation
circuit is good to at least 100 times the
|
|
|
maximum reading in the highest range. No
special probes are required. New ergonomic
|
|
|
design decreases worker’s fatigue over
long periods of use.
|
|
|
|
|
|
General-Purpose Detectors are available with
uncompensated halogen-quenched
|
|
|
sensors for measuring alpha, beta, gamma, and X-ray radiation;
select meters with
|
|
|
energy-compensated sensors for
increased sensitivity to gamma and X-ray radiation.
|
|
|
|
|
|
Radiography
Detector
has a wide range with four range multipliers (x1, x10, x100, and x1000).
|
|
|
Compensated
sensor provides increased sensitivity to low-level gamma and X-ray emissions
-
|
|
|
detects background levels as low as 5 cpm.
|
|
|
|
|
|
What’s included: padded carrying case.
Meters operate on one 9V battery (order separately below).
