General Purpose Radiation Survey Meter/Geiger Counter
Rad 100™
-
The RAD 100™ is a general purpose radiation survey meter/geiger counter that detects and measures alpha, beta, gamma, and X-radiation. It is intended for personal safety and educational purposes. Like the popular Radalert® 100X, the RAD 100™ features a 3-second update on its digital liquid crystal display (LCD). The LCD shows the current radiation level in your choice of microSieverts per hour (SI units) or mR/hr for gamma radiation measurements. For mixed sources (alpha, beta, gamma) the CPM mode is recommended. This instrument also offers an accumulated total and timer function, up to 9,999,000 counts and 40 hours. A red LED blinks and a beeper chirps with each count (the chirp can be muted). This is a professional instrument that is also easy to learn to use and to operate, and carries the industry leading Medcom warranty (2 years overall limited to 1 year on the GM sensor). Many instruments designed by the Medcom team are still working perfectly after 30 years of use, so this instrument should provide a lifetime of useful information.

Geiger Counters
-
A geiger counter detects nuclear radiation by measuring the emission of ionizing radiation of alpha particles, beta particles and gamma rays. Also referred to as a radiation detector, a geiger counter consists of two main elements: the processing electronics and the geiger tube. The geiger tube is filled with low-pressure inert gas like helium, argon or neon. If radioactive radiation occurs, the inert gas is ionized. An anode within the geiger tube registers the quantity of ionized particles numerically correlating with the strength of the radioactive radiation. The radioactivity measurement is then displayed on the LCD screen of the geiger counter or radiation detector.It is very important to measure radioactivity as well as to classify radioactivity values. For example, terrestrial gamma radiation is measured according to general values from 0.03 - 0.3 µSv/h (microsievert / hour). This "normal" oscillation range is conditioned by natural radioactive elements in the ground such as uranium and potassium. To calculate this factor, one must take into consideration cosmic radiation. For example, when considering cosmic radiation, the maximum radioactivity content at Schneefernerhaus, the highest-located German environmental research station, is approximately equal to 110 µSv/h.At PCE Instruments, you will find three types of geiger counter or raditation detection devices to help you measure radioactivity: 1) alpha radioactivity meters, 2) meters for detecting alpha, beta and gamma radioactivity and 3) radioactivity meters for human beings.

Naneos Particle Solutions gmbh
Exhaust gas contains a lot of humidity, which can condense in the measuring device when the gas cools down. This could lead to problems with the measurement. Therefore, corresponding sensors are heated or the gas gets previously diluted. Exhaust gases from petrol and natural gas vehicles, however, contain a lot more humidity, which is why the device should only be used for diesel exhaust gases.
