Features

Integrated, Lightweight Design Simplifies Frisking

High-Impact Plastic with Water-Resistant Rubber Seals

Employs Standard 15 cm² GM Pancake Detector

Ratemeter, Peak, and Scaler Operating Modes

Simple Two-Button Operation

Count Rate and Scaler Alarms

Automatic LCD Backlight Activation
Operation is kept extremely simple through the use of just two buttons. A useful feature employed in the design is the MAX mode, which captures the highest or peak count rate. It is particularly convenient whenever the display is not directly visible. 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.
Specifications
Detector: Pancake GM (Geiger-Mueller) detector, stainless steel screen
Window Area: Active: 15 cm² (2.3 in²); Open: 12.2 cm² (1.9 in²)

Efficiency (4pi) (surface plane):
Alpha: 11% for ²³⁹Pu
Beta: 18% for ⁹⁹Tc; 32% for ³²P; 2% for ¹⁴C; 22% for ⁹⁰Sr/⁹⁰Y; 0.2% for ¹²⁵I
Gamma: 3300 cpm/mR/hr or 5.5 cps/µSv/hr (¹³⁷Cs); < 1% for ^99mTc

Resolving Time: Approximately 100 microsec as defined by IEC 60325
Alarms: Count rate and scaler alarm set points adjustable over the display range
Overload: High count rate saturation protection prevents false display of lower count rates
Zero Protection: After 60 seconds of no pulses from detector, unit will flash a zero reading and the alarm audio will be triggered
LCD Display: 3½ digit LCD with large 12.7 mm (0.5 in.) digits, (k)cpm, (k)cps, low battery indicator
Range: 0.1 cps to 1.99 kcps, or 1 cpm to 99.9 kcpm
Backlight: Built-in ambient light sensor automatically activates low-power LED backlight, or may be configured for 'Continuous On' operations (will reduce battery life)

Controls: Two pushbuttons
OFF/ON/QUIET: Press to turn ON, tap to alternate between 'click' audio and QUIET, hold for OFF
MODE: Alternates between Normal (count rate) and Max (captures peak rate), and Scaler (user-selectable preset count time from 0 to 20 minutes). Each mode is separately programmable so it can be active or turned off.

Response Time: User-selectable from 1 to 60 seconds, or Auto-Response Rate FAST or SLOW
Click Audio: Greater than 60 dB at 0.6 m (2 ft)
Power: Two "AA" batteries
Battery Life: Approximately 1000 hours of operations (as low as 500 hours with backlight configured for 'Continuous On'), 16-hour low battery warning
Construction: High-impact plastic with water-resistant rubber seals, separate battery compartment and rubber overmold
Environmental Rating: NEMA 3/ IP 53
Surface Emissions Rate: ≤15%
Distance from Surface Plane to Grill: 0.32 cm (1/8")
Size: 2.7" W x 10.7" L x 1.8" H (6.9 x 27.2 x 4.6 cm)
Weight: 1.0 lb (0.45 kg)
