NFA-SERIES 3D NF Analyser with Data Logger
The NFA 1000 requires only very few settings and is able to process hundreds of thousands of pieces of information per second in the background, allowing you to capture the most important parameters at one glance in the process of measuring.
At the same time, all relevant measurement and instrument data are simultaneously and continuously recorded onto a standard SD memory card, linked with the possibility of dictating audio notes "live" directly into the device. A minimum of effort will therefore provide a maximum of information for a detailed analysis on your PC later on.
This leaves you with more time for the essential task: The best possible consultation of your customer. The PC evaluation software "NFA-see" included in the scope of supply requires no installation, impressively displays the measuring results, supplies statistical evaluations in real time, and provides all information you need for your measurement protocol in a flash.

CD V-715 Civil Defense High-Range Radiation Detection Survey Meter
3.25 pounds, die cast aluminum and drawn steel case, watertight, will float. Powered with one D-sized battery, continuously for 150 hours, longer if on intermittent basis.
Instrument accuracy on any of its four ranges is within +- 20% of true dose rate. Accuracy maintained throughout temperature ranges of -20 F to +125 F, relative humidities to 100% and altitudes up to 25,000'.
The following three survey meters are the most common Civil Defense high-range meters. The detector on all these high-range survey meters is an ionization chamber. It measures gamma radiation. The R/hr in the ranges indicated below refers to Roentgen per hour exposure rate.
They each have a 1-5 numbered meter range and four multiplier scales: X100, X10, X1 and X0.1, with the exception of the CD V-720, that does not have the X0.1 scale. The CD V-715 and CD V-717 with the multiplier scale, X0.1, provides that the 0 - 5 range would be read as 0 - .5 R/hr when it's selected. Click Here
GM-180 Geiger Counter Radiation Detector
The GM-180 contains four geiger mueller tubes, capable of detecting alpha, beta, and gamma / x-ray radiation. Each time a radiation particle enters the sensing window, it is detected, and the software on the attached computer is informed of this event.
By adding up the number of detections per minute, the Counts Per Minute (CPM) is calculated and displayed. This number is a relative indicator of the amount of radiation present.
Two versions of the GM-180 are available. One includes a USB adapter and plugs in to a USB port on your computer (Windows, Macintosh or Linux), and includes a 6 ft long USB cable. The other version plugs into a standard RS-232 serial port on your computer, and comes with a cable for the standard 9 pin PC serial port.
Since the GM-180 is self powered by the computer's serial port, no batteries or external power adapters are needed! You can operate them anywhere you can take your computer or laptop! Click Here
451B Ion Chamber Survey Meter with Beta Slide
The 451B state-of-the-art ion chamber survey meter is a handheld battery operated unit designed for use in both rugged and normal environments.
The 451B includes a sliding beta shield to serve as an equilibrium thickness for photon measurements and enables beta discrimination.
The 451B has auto-ranging and measure radiation rate and accumulated dose from various radiation sources (beta, x-ray, gamma).
The ion chamber detector allows for a fast response time to radiation from leakage, scatter beams, and pinholes.
Additionally, the low-noise chamber bias supply provides for fast background-settling time.
The digital display features an analog bar graph, 2.5 digital readout, low battery, and freeze (peak hold) mode indicators, and an automatic backlight function.
User controls consist of an ON/OFF button and a MODE button. The case is constructed of lightweight, high strength materials and is sealed against moisture.

RadalertT 50
The Radalert 50, our most popular product, is a general purpose geiger counter. It measures alpha, beta, gamma, and x-radiation. Its digital display shows readings in your choice of counts per minute (cpm) or mR/hr, up to 50,000 cpm or 50 mR/hr, or in accumulated counts. A red LED blinks and a beeper chirps with each count (the chirp can be muted). An audible alert sounds when the radiation reaches a user-adjustable level. The Radalert 50 meets CE certification requirements for Europe.
Determining whether you need a general purpose Geiger Counter or a Surface Contamination Meter is dependent primarily on your intended use of the instrument. The hand-held Geiger Counters are suitable for a wide variety of applications that include detecting radioactive sources, surveying ambient or background levels of radiation, monitoring radiation levels, surveying for radioactive contamination, monitoring personal radiation exposure, and determining whether certain machines are "leaking" radiation.
The Surface Contamination Meters may be used for all of these applications as well, but they were specifically designed for use in laboratories and medical or research facilities where radioactive substances are in use. These instruments are also suitable for many applications in nuclear power plants and scrap metal facilities.
The Radalert 100 and the Inspector instruments (i.e., the Inspector Alert & Inspector EXP) are very similar in functionality. The primary difference between them is the size and geometry of the Geiger tube. In the Radalert 100, the tube is a long thin cylinder with a mica end window through which alpha, beta, low-level gamma, and x radiation can pass. The Inspector Alert & EXP both use a larger Geiger tube with a "pancake" geometry that provides a much larger surface area for the mica window and, thus, greater sensitivity to radionuclides and a faster response time. This is the type of detector recommended by regulatory agencies and health physicists for surface contamination measurements of a number of commonly-used radionuclides, including C-14, P-32, S-35, Cr-51, I-125, Na-22, Cl-36, Ca-45, Co-57, Zn-65, Tc-99m, In-111, and Ti-201. (For the Cl-36 and Ca-45, the measurement should be made using the wipe test attachment). Click Here
