The Model TBM-IC-XRAY provides accurate compliance testing of a wide variety of X-Ray equipment. The unit is now more compact and lightweight, featuring the latest, most stable, drift-free electrometer technology. This Ion Chamber consists of an air-equivalent ion chamber coupled to a stable solid state MOSFET input electrometer with a built-in A to D converter to read out directly in mR/h or mR. Rate Range is 0.01 mR/h to 100.00 mR/h in one range. Dose range is 0.01 mR to 10 R.

Features:

One-hand operation
Digital Display: 6 digit-rate, 6 digits integrate
Lightweight design weighs only 2.4 lbs
Detects axially below 15 KeV Gamma / X-RAY
Flat rate response and air equivalent
