Model 9-4 The Ludlum 9-4 is a rugged air ionization chamber for performing beta-gamma dose rate measurements over a five-decade span ranging from 0-500 mSv/hr (0-50 R/hr). The ion chamber automatically compensates for changes in temperature and pressure. The chamber wall, including the instrument case, is 1000 mg/cm2. A 1000 mg/cm2 retractable beta shield allows beta measurement with a 7 mg/cm2 window. The six-position selector switch selects Off, x10K, x1K, x100, x10 and x1. Other controls include an on/off switch for a meter light, reset and battery test buttons, and a zero adjustment knob. The Model 9-4 is equipped with a serial interface for calibration. An optional calibration kit is available, which supplies the necessary interface cable, software, calibration can, pressure pump, and serial-to-USB converter. ë
