## Overview

The GCA-06 Professional Digital Geiger Counter is a handheld radiation monitor featuring an American-made LND712 GM tube. It offers ultra-fine 0.001 mR/hr resolution and a broad 1000 mR/hr detection range, capable of detecting alpha, beta, X-ray, and gamma radiation. ANSI N323A calibration is available, ensuring professional-grade accuracy. Compact and lightweight, it’s designed for fast, reliable radiation detection anywhere.

## Description

The GCA-06 is a hand held personal nuclear radiation detector. A proven track record for detecting nuclear radiation in hospitals, medical research, industrial settings, transport containers, top soil, granitite table tops, scrap metal, oil fields, objects and interior spaces.  The GCA-06 detects Alpha, Beta, X-ray and Gamma radiation above 3 MeV, 50 KeV, and 7 KeV respectively.  Easy to read LCD is a 2 line by 16 character that provides a current count and radiation level readout. Simple front panel instrument controls make the GCA-06W easy to use. Toggle switches control all the front panel options. User can select time period, type of measurements (Imperial or Metric). Measurments (counts per second) are converted into radiation levels (mR/hr or mSv/hr). Time selection switch allows Counts Per Second (CPS) or Counts Per Minute (CPM) mode. Factory calibrated using an NIST traceable source to insure measurements. Our NRC certification is available at additional cost from the manufacturer. The NRC certification certifies your Geiger counter has passed ANSI-STD N323A calibration using a NIST traceable source from an independent US licensed laboratory conforming to United States Nuclear Regulatory Commission NRC regulations 10-CFR-34 and 10-CFR-35 standards (available at additional costs through the manufacturer).  Options: Jack for Headphones or External Speaker. External Power Supply included. 3.5mm Data Port for WIN PC and microcontroller interface. WIN PC program requires optional 3.5mm to USB data cable.  Secondary indicators; audio (clicks) and visual (LED) included. 9V battery (mobile operation) not included.
