The Frisker is a modern, general purpose, radiation detection instrument used by a variety of industries. It employs a GM pancake detector that is sensitive to alpha, beta, and gamma radiation. This unit is identical to SEI’s Model Ranger in every way except for the form factor which follows the traditional GM Pancake detector at the end of a handle but has all the electronics built-in so a separate electronics readout unit is no longer necessary.
The measurement is presented on a backlit LCD in digital format using large size numbers so there’s no confusing analog meter faces and range scales to interpret. The measurement can be set to display either CPS (counts per second) for contamination measurements or in mR/hr for viewing the exposure rate via a front panel switch. A built-in timer enables counting over a user-input time interval to acquire greater measurement accuracy.
