  • Model 2401-EC - Pocket Size Radiation Detection Meter

    Model 2401-EC - Pocket Size Radiation Detection Meter

    The Model 2401-EC instrument is a pocket radiation detection meter with an integrated energy compensated GM tube for measuring gamma exposure.  The meter measures 0-200 mR/hr exposure rate and also 0-210,000 cpm via separate scales. The metal case offers excellent protection against abuse.  The overall and integrated design facilitate ease of use.

  • Model 2401-EW - Pocket Size Exposure & A/B/G Count Ratemeter

    Model 2401-EW - Pocket Size Exposure & A/B/G Count Ratemeter

    The Model 2401-EW instrument is a general purpose, pocket radiation detection meter that employs an end-window type GM detector. The detector is conveniently packaged inside the instrument, with a protective screen covering located along the middle of the top end of the instrument. The meter presents two scales: CPM for contamination measurements, and mR/hr for exposure rate.

  • Model 9-3 Series - Ion Chamber Survey Meter

    Model 9-3 Series - Ion Chamber Survey Meter

    The Ludlum 9-3 ion chamber is a rugged air ionization chamber for performing beta-gamma dose rate measurements over a five-decade span ranging from background to 500 mSv/h (50 R/hr). 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 switch selects Off, x10K, x1K, x100, x10 and x1. Each range has a front-panel, mounted...

  • Model 2403 - Pocket Size Ratemeter

    Model 2403 - Pocket Size Ratemeter

    The Model 2403 is a pocket ratemeter with an analog display that may be connected to any one of a number of available GM type detectors.  This unit supports mR/hr exposure and cpm countrate measurements.  The metallic case and convenient make this a nice tool to for a wide variety of applications.

  • Model 2221 - Ratemeter and Scaler

    Model 2221 - Ratemeter and Scaler

    Here's a general purpose ratemeter and scaler with just about every bell and whistle you'll ever need or want. This ultimate tool provides a customary analog display for optimally viewing the count rate and rate of change through all possible four decades of display. It is accompanied by a digital LCD, which can present either the ratemeter data or be switched over to read the scaler counts.

  • Model 2350-1 Series - General Purpose Ratemeter/Scaler/Data Logger

    Model 2350-1 Series - General Purpose Ratemeter/Scaler/Data Logger

    The general purpose Model 2350-1 is Ludlum's most advanced ratemeter/scaler/data logger, and is designed to satisfy a wide range of applications. The large backlit LCD presents bar graphs, digital readings, and logged data on an 8-line by 15-character display. Up to 1000 data points can be stored, along with the location, date/time stamp, detector, count mode, count time, logging mode, and sample number. Location code information can be input via an...
