Radiation Monitor

Model R007, Radiation meter

Small and light enough to go anywhere, yet sensitive enough to detect minuscule amounts of Gamma, Beta or X-rays. Excellent for scanning lab work areas and clothing , for traces of radioactivity exposure. Useful in school labs for geology and science projects. One button operation, can be used by untrained personnel. Uses a Geiger-Mueller tube detector. The meter registers 0.1 to 10mR / hr. (milli-Roentgen), on a unique logarithmic scale.

Audible clicking will increase with the amount of background radiation. Beeping begins at 20mR / hr, increasing in frequency in proportion to the radiation level. Powered by 9V battery, included, which lasts 50 hours at normal background levels. Dimension: 6-3/8" x 3-1/4" x 1-3/8". Weight: 8.5oz.

Range: 0.1 to 10mR / hr & 1-100uSv / hr.


Model R026, Radiation meter

Same design as radiation meter R007, but with a broader scale, 0-100mR / hr. If required this unit can be calibrated to NRC standards by a government authorized test facility. Used in applications where radiation may be present in greater than trace amounts.

Range: 0-100mR / hr. & 0-1000uSv / hr.

Cat. No. 21723,     Detector radiation

Radiation Monitor

Offers excellent sensitivity to low-levels of alpha, beta and gamma rays!

The Inspector EXP™, a small handheld microprocessor-based instrument, offers excellent sensitivity to low levels of alpha, beta, gamma, and x-rays. The digital readout is displayed with a red count light and audible beep, providing constant indications of the radiation level. Display will update every 3 seconds. At low background levels, the update is the moving average for the past 30 seconds. Times period for moving average decrease as the radiation level increase. Other benefits include an adjustable timer and external calibration controls. A utility menu offers several options : 3 second fast response; switches from mR/hr and CPM to µSv/hr and CPS; reset the cal factor to 100; probe adjustment settings, adjust the CAL factor; reset all settings to default.

Unit comes with external pancake probe and cable and carrying case with clear window to provide full view of the read out. Requires one 9V battery

Cat. No. 1918,   Radiation Monitor (with probe and cable)

Radiation Survey Meters

Incorporates high sensitivity electronics

Separate and specific non-interacting potentiometers for each range, high-voltage adjustment, probe saturation and input sensitivity

Loud audible signal corresponding to probe signal intensity

This radiation survey meter incorporates high sensitivity electronics in a rugged, moisture resistant, cast aluminum case for extra long-term reliability and durability. This radiation meter has separate and specific non-interacting potentiometers for each range, for high-voltage adjustment, for probe saturation and for input sensitivity. Low battery condition or probe saturation indicated by LED indicators. A loud audible signal, corresponding to probe signal intensity, may be activated or deactivated with a conveniently located switch on the front panel. Panel controls include: Main selector switch for OFF, X100, X10, X1; Voltage switch for Battery X1 and HV X100; Audio ON/OFF switch; Response Potentiometer - 4 to 20 second, continuously visible.

Both 3327A and 3327B have an earphone jack for optional earphones. 3327B features an auto-ranging analog display and is self calibrating for CPM. Both 3327A and 3327B Radiation Survey Meters are engineered, with the probes listed below, for most applications. Rugged, low cost, these meters are designed to provide many years of reliable operation. Two 9V alkaline batteries provide 200 hours of nominal operation
