Scan items for radiation, detect Naturally Occurring Radioactive Materials (NORM) and continuously monitor your environment. The PRM-8000 is an ideal solution for First Responders, Homeland Security, Medical Safety, Educators, Researchers and Geologists. This Geiger counter delivers laboratory grade performance in a small package. The two-line, alphanumeric display supports both English and Japanese languages promoting ease-of-use and concise measurement. The display is backlit to support low-light conditions. The device's Radiation Monitoring Engine (RME) is always-on collecting measurements and statistics enabling rapid environment assessment. Using only one key, users can scroll through several screens that display present, average, maximum and minimum measurements in uR/hr, mR/hr, uSv/hr, Counts per Second (CPS) or Counts per Minute (CPM). The PRM-8000 instrument not only records the maximum radiation measured, but also displays the time and date at which the maximum occurred. Battery life is over 6-years under normal conditions from a single, readily-available, 9-volt lithium battery that is user-installable without soldering. Standard alkaline 9-volt batteries available everywhere provide over 3-years of life under normal conditions. With over 100K bytes of data logging memory included, the PRM-8000 can autonomously store up to 91,466 minutes or hours of time-stamped measurements. These measurements can then be uploaded to a PC in CSV format for analysis. A user-settable dose rate alarm sounds an audible alert when the measured radiation level exceeds that of the alarm level setting. Designed by Mazur Instruments and manufactured in the USA, the PRM-8000 includes abundant I/O options including support for headphones, external speakers, external power and PC/Mac USB data exchange (requires optional 3.5mm to USB adapter cable). Minimum energy sensitivity alpha (2.5 MeV), beta (50 keV), gamma/X rays (10 keV). Gamma sensitivity: 1,000 CPM/mR/hr (Cs-137).


Our Comments:

This meter is capable of measuring beta and gamma radiation, as well as alpha radiation and x-rays.

It is a rather hefty unit, measuring 5.625 x 3.25 x 1.367 inches, but it is robust – designed for serious work.

The PRM-8000 monitors Average, Minimum and Maximum dose rates in microRoentgen/hour, milleRoentgen/hour, microSievert/hour, Counts Per Second or Counts Per Minute.

Claimed battery life is outstanding – over 6-years under normal conditions from a single, readily available 9-volt lithium battery that is user-installable.

Designed by Mazur Instruments and manufactured in the USA, the PRM-8000 Geiger counter and nuclear radiation monitor features support for headphones, external speakers, external power and USB data exchange (using optional USB adapter cable).

Amazon customer reviews are very complimentary.

 

This is one meter I wouldn’t mind sharing!

Radex RD1503+ Geiger Counter

Amazon Price: $199.95 $162.95 You save: $37.00 (19%) (as of June 23, 2018 3:01 pm - Details) Product prices and availability are accurate as of the date/time indicated and are subject to change.

ATTENTION: As of August 1st, 2013, Quarta-Rad upgraded RADEX 1503 to RADEX 1503 Plus. Upgraded firmware, additional features, and cost the same as RADEX 1503. Don't be fooled by online vendors selling old and unsupported RADEX 1503 model as new. When you buy RADEX 1503 online, make sure it is RADEX 1503 Plus (Radex 1503+)
Now there is a better, stronger and more advanced version of our best-selling workhorse – the RD1503.
Ever since the introduction of the original RD1503, customers have been asking for additional functions and requested certain improvements on the existing design. We have listened and incorporated many new capabilities into RD1503+:
New and Improved Features of RADEX RD1503+

+ Graduated change of a threshold signal in the range from 0.10 to 0.90 µSv/h with an 0.10 µSv/h interval (available in individual settings).

+ Value of the background dose rate is saved even when the device is turned off.

+ Now displays the difference of the dose rate between the averaged and background values.

+ Includes vibration signal and audio alarm (both adjustable).

+ Added animation of the pressed command button (the icon of the button starts blinking on the display).

This new device allows a quick and easy way to check radiation background of top soil, non-edibles and interior premises.
The quality of indication of any dosimeter depends primarily on the built-in detector of ionizing radiation. RADEX RD1503+ contains a low-voltage SBM20-1 type Geiger-Muller counter of beta- and gamma-radiation which is found used in professional dosimetric equipment.
An expert scientific tool that’s made for an average Joe.

Quick, Simple, and now better than ever!


Our comments:

Let’s face it, not everyone needs a Geiger counter – some of us just want one! This one seems to do an excellent job and offers great value too.

Remember how concerned we all were in 2011 when the Fukashima disaster struck? You could not buy a Geiger counter for love nor money. Suppliers sold out within hours!

So don’t wait for the next nuclear disaster to buy one.

This unit is made in Russia. It measures beta and gamma radiation, which is what you need for nuclear radiation.

Apparently it is quite popular in Japan. The Japanese would be discerning customers, don’t you think?

The description doesn’t mention alpha particles (e.g. from radon gas) or x-rays, so this meter won’t measure these kinds of radiation.

Some Amazon reviews complained about the manual, which is apparently a poor translation into English.

But overall, at this price, you could do a lot worse.

 

It’s good to be prepared, don’t you think?
