Internal Halogen-quenched, uncompensated GM tube with thin mica window, 1.4-2.0 mg/cm2 areal density. Effective diameter of window is 45 mm (1.77 in.). Radiation symbol on front label marks the center of the detector.
Display will update every 3 seconds. At low background levels, the update is the moving average for the past 30-second time period. The timed period for the moving average decreases as the radiation level increases.

RDS-31 Multi-purpose Survey Meter is a small hand held, battery operated survey instrument using an energy compensated GM-tube as primary detector. Due to its versatile functions and durability it is suited for a wide range of applications e.g. in civil defense, industrial and laboratory use.
ONYX® can be used as a stand alone pocketable instrument, or it can connect to the internet and share data. The ONYX has a six button touch sensitive keypad that allows for easy use of a wide variety of functions such as graphic display of data, adjustment of audio chirp, data logging, changing units of measurement and calibration. ONYX also permits the user to upgrade the software running on the device to the latest version using a simple internet download feature.
The Radalert® 100X is a general purpose geiger counter that measures alpha, beta, gamma, and X-radiation.
Features of the Radalert® 100X, include a three-second update and a Utility Menu that allows you to change the default settings for several operating parameters. Its digital liquid crystal display (LCD) shows the current radiation level in your choice of SI units (microsieverts per hour) from .000 to 1,100 and counts per minute (CPM) from 0 to 350,000 or counts per second (CPS) from 0 to 3,500. For users of conventional units mR/hr (milliroentgens per hour) from .000 to 110 and CPM are optional in the Utility Menu. This instrument also offers an accumulated total and timer function, up to 9,999,000 counts and 40 hours.

The RDS-80A Surface Contamination Meter is a versatile contamination detector which has been designed for a wide range of applications in different fields of radiation protection in nuclear industry, rescue and other operations, involving a potential for abnormal contamination levels.
The Sentry Personal Alarming Rate Meter is designed to ensure the personal safety of radiologists and other personnel that work in occupations with potential x-ray or gamma exposure.
The CT007-F is a compact alpha, beta, gamma detector. This makes it suitable for identifying radioactive contamination.
Unlike pancake Geiger-Mueller tube based instruments, it is light, compact, and durable.
The CT007-F is sensitive enough to pick up the radiation from household items, but can still measure up to dangerous levels. It is easy to use and can even connect wirelessly to your phone. The phone provides a rich user interface and allows for time and date stamped data logging with GPS coordinates. The data can be logged to a file on your phone as well as optionally being logged to RadResponder. On the back is the sensor with an alpha/beta shield. This shield can be closed to take gamma only measurements, or opened to reveal the sensor window and take alpha and beta readings. This shield also keeps the sensor safe during transport.
