SMALL SIZE AND WEIGHT
HPI model 4083 Canary III is an electronic personnel dosimeter.
It is the ideal instrument for monitoring a wide range of exposures.
The Canary III integrates dose on a digital display from 1 mR to
999,999 mR. It incorporates an adjustable beeper as well as an adjustable
integrate alarm. The memory function is also user selected. The
display is automatically reset when the on-off switch is moved from
off to on.
The battery life of the Canary III is 2000 hours or almost a year
of normal work-time use. The battery test button is conveniently
placed on top of the instrument along with the power switch and
The Canary is housed in a small anodized aluminum case that easily
fits into a pocket or clips to a belt or lanyard.

the chirper except both cannot be set to the same number; the .1
mR setting is approximate.
Single turn control adjustment
solder jumper preset for proper energy response.
Jumper: if on, turns the display on all the time even when the instrument
is turned off. Display will reset when instrument is turned on,but
reading will stay when the instrument is turned off. Battery test
will check if instrument is on.
