  • Product Description

    inspdisplaytn.jpgThe IMI Inspector Alert v2, by International Medcom, among the most sensitive pocket Geiger counter available, offers a digital readout on a crisp, clear, easy-to-read LCD display, as shown in these pictures.  The readout is displayed also with a red count light and audible beep (play this sound file), providing instant indications of the radiation level.

     

    inspwindowtn.jpgThis model is also built around a very large , pancake-style Geiger-Mueller tube, with a diameter of 45 mm (1.75 in), increasing the efficiency of radioactivity detection, and offering excellent sensitivity to low levels of Alpha and Beta, in addition to normal Gamma and X-ray detection.   See picture at left.  This feature makes the Inspector suitable for applications requiring higher levels of sensitivity such as checking food for radioactive contamination, subject to certain qualifications - click on the link.

    The  Inspector Alert is in part named for its user-settable Audible Alert.  You can see the controls on the top panel of the unit (right).insptoptn.jpg

    When the Mode switch on the front of the instrument is set to Total/Timer, you can engage an adjustable timer to set sampling periods of 1 minute, 10 minutes, or 1 hour, up to 24 hours.  See the photo at left.  This is an especially useful feature for establishing a background count, or for low level radiation detection.insppaneltn.jpg

    This unit also has an output port to record counts on a computer or data logger, as shown in the picture below.  Select the navigation button above or click on this link for more on Data Output and Software.  inspportstn.jpgThis port can alternatively be used for audio output through earphones.  An external Calibration Input port is also located on the side of the instrument.

     

    The Inspector Alert also comes with a padded nylon carrying case (left) with belt loop.radcasetn.jpg

    The Inspector Alert also comes with perhaps the best Operation Manual of any Geiger counter in our selection - in printed, booklet form, and very user friendly and thorough.

     

    inspmanualtn.jpgThe Inspector Alert is among the most popular Geiger counter within our selection.  If you want a Pocket Geiger Counter with ultra sensitivity, user-adjustable audible alert, a timer and/or data port, and prefer a digital readout versus an analog meter, we recommend this unit.

    This item typically ships out within 1 business day.
