Integrated Pancake Frisker - Model 26
Introduction

Frisking people and objects for alpha & beta contamination can be awkward because manipulation of the cable, detector, and electronics requires the use of both hands. The cable-less Ludlum Model 26 consolidates the electronics and the detector into one ergonomic housing. This optimized configuration incorporates a standard 15.51 cm² GM pancake probe, loud audio “click” output, and large auto-ranging LCD display with automatic back lighting into one convenient package, making it easier than ever to detect contamination.

Operation is kept extremely simple through the use of just two buttons. Another useful feature, especially when the display is not always directly visible, is the 'MAX' mode that captures the highest or peak count rate. The scaler mode, with a preset count time, allows the user to take a discrete measurement. This system also incorporates low power circuitry, delivering hundreds of hours of use with just two standard “AA” size batteries. The calibrator can protect parameters (cps/cpm, response time, alarm points, & scaler time) or allow the user to adjust them.
 
The Model 26 series may also be ordered with a standard 1/8 inch plug, mono headphone jack to better monitor the instrument's audible output in noisy environments. Part Number 4498-538. See more under the Options tab.
