The Ludlum Model 9-7S is a stretch pole and ratemeter that can be attached to any compatible ion chamber (sold separately). This instrument provides remote monitoring in high-range beta and gamma fields. The gamma measurement range is 0 to 19.99 kR/hr, covered by three separate detectors (see Detectors tab). These ion chambers are connected directly to the instrument at the tip of the pole, and the Model 9-7S controller automatically recognizes which detector is connected so no recalibration or adjustment is required when switching detectors. The backlit LCD displays three easily-readable digits together with a floating decimal point to indicate the measurement along the R/hr scale. When connected to the highest range detector, a separate kR/hr indicator is prominently illuminated to warn the operator of the higher scale in use.
