The 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 beeper.
The Canary is housed in a small anodized aluminum case that easily fits into a pocket or clips to a belt or lanyard.
