IMI ONYX-NX10 Description：

Product Manual Datasheet

ONYX features a modern, streamlined look and the use of advanced technologies, making it a one-of-a-kind Geiger Counter. It weighs only 7 oz. (200g.) and measures a mere 5.1 X 2.6 X 0.9 in. (72 X 37 X 13 mm.) making it easy to transport. Despite its compact size ONYX is capable of detecting alpha, beta and gamma radiation with the same sensitivity as the IMI Inspector Alert?, and like the IMI Inspector Alert? V2, ONYX is optimized for surface contamination measurements through use of its 2 in. pancake Geiger Mueller tube.

Data are easy to read in a variety of formats ( μR/hr per hour, Counts Per Minute, μSv/h and Total Counts – with Timer) on the 128 X 128 color OLED display that measures 1.88 in. (47.9mm.) diagonally. In addition, ONYX is designed to share data through its micro-USB port. Twitter data are transferred using QR code displayed on the OLED in combination with a smart phone with a QR Code scanner.

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 version being shipped with the instrument is the most up to date.
