Ranger Radiation Survey Meter by SE International"Ranger" Radiation Detector / Scaler- Internal Pancake G-M

The handheld Ranger is a small, rugged, lightweight, microprocessor-based instrument which is sensitive to low levels of alpha, beta, gamma, and x-rays. The Ranger can easily swtich units, with a simple control: mR/hr, uSv/hr, cpm, cps. It features built-in efficiencies for common isotopes to estimate activity in Bq and DPM. A scaler function allows for counts taken over a given period of time, user adjustable. Noteworthy features include a backlit digital display, a red count light, audible chirp and adjustable alarm. Internal memory and the Observer USB Software (free) allow the user to download data, set computer alarms, and calibrate the instrument. A wipe test plate for swipes is an option, sold seperately. Please follow the link for a detailed demonstration video. more...

TBM IC Mark Ion Chamber by Technical AssociatesTBM Mark V Ion Chamber

The TBM-IC-MV Ion chamber is one of the most accurate ways to measure Gamma and X-Ray Radiation. Most ion chambers cost considerably more, but this model is only $1914. The flat response TBM-IC-MV is a fast, sensitive ion chamber survey meter which measures gamma radiation, and detects some alphas, betas. The survey meter features a 2.5 inch diameter x 3.5 inch length air ion chamber coupled to a stable solid state Mosfet input electrometer. Rate range is 0.1 mR/h to 9.999 R/h in a single range. Dose range is 0.01mR - 99.9R in a single range. Please follow the link for a detailed demonstration video. more...
