Model 26S

The optimized configuration includes a standard 1 x 1 equivalent detector, loud Sigma audio, and large auto-ranging LCD display with automatic backlighting. These features are combined in one convenient package making it easy to detect and measure gamma fields.

Operation of the Model 26S is kept simple through the use of just three buttons that are strategically placed for one-handed operation. Three modes of operation – RATE, MAX, and COUNT – are available. The RATE mode displays current radiation levels in terms of rate. MAX mode captures the highest rate detected so it is possible to determine a peak rate during frisking operations when the display is not visible. COUNT mode allows the operator to perform a survey for a predetermined time. The user-selected units can display results in a measurement of scaler counts, activity (disintegrations), time-averaged rates, or even accumulated dose.

Low-power circuitry means two standard “AA” sized batteries deliver hundreds of hours of instrument operation. The parameters may be protected via internal dipswitch, or the calibrator may allow the user to adjust them. Other features include a backlight triggered by low-level ambient lighting (may be configured for “Continuous On” operation) and audio that may be silenced for both RATE and MAX modes.
