GC01 Semiprofessional Geiger Counter With Pancake Probe.

We present our modified version with Pancake probe of the well-known GC01 Geiger Counter, where compared to the original model the following changes have been implemented:

• First of all we replaced the small and inefficient original Chinese Geiger tube, with a high-performance professional Pancake-type circular probe, Made in the USA. which can detect with extreme sensitivity in addition to beta and range radiation, X-rays and also the more critical ALFA radiation.
• Replacement of the original rear cover with a new one equipped with a circular window. This important change allows the GC01, Thanks also to the new Pancake probe to easily detect Alfa radiation. More in detail, The new cover includes a circular window equipped with a protective grid with a diameter of about 46mm, which allows you to expose the active surface of the geiger pancake tube, directly outwards, allowing him to detect Alfa radiation without impediments.
• ADAPTER OF THE HIGH Tension that feeds the new Geiger Pancake tube, which is now correctly set to the nominal value of about 500V. This allows the Geiger Pancake tube to always function with maximum sensitivity and precision.
• Installed a new firmware in the internal microcontroller now available with menu in Italian and English. This firmware is much more advanced than the original one, improves general performance and also implements the useful Ticker function. It is a version we ourselves adapted, Basata Sul firmware OpenSource Gissio@Radpro, with many advanced measurement features and a new much more rational graphics.
• New advanced algorithms for a refined radioactivity measurement. Our GC-01 /PNK now thanks to its new advanced firmware, can measure the dose with renewed precision, the level of instant installment, and medium of exposure to ionizing radiation. Also in addition to being possible to customize the acquisition times, The tool can show the graphic trend of radioactivity in the domain of time.
• Dose Calculation: The instrument now always thanks to the new advanced firmware, can automatically calculate the dose of ionizing radiation exposure over time, displaying it on the display in real time and possibly generating an audible alarm if a certain programmable threshold is exceeded.
• Implementation of a cleaned sound alarm. The alarm can be activated if a dose and/or instant radioactivity values ​​are acquired which exceed a certain pre-setting threshold value.
• Diet: The GC01 is equipped as standard with an internal accumulator from 3.7V 1200mAh and a USB socket that currently serves to be able to be recharged via a PC or a common network adapter to 220V (not provided).

The new features of the enhanced FNIRSI Geiger Counter at a glance.

After our intervention the small geiger counter GC-01 has become a semi-professional detector with Pancake probe. Now it is decidedly much more sensitive and precise than most of the low-cost Geiger Counters well advertised by the competition and passed off as professional.

It can detect all Alpha radiation with high efficiency and reasonable precision, Beta, Gamma and X -rays, while also using different settable measurement modes.

As already mentioned, These good characteristics are mainly due to the special professional-class Pancake probe, to the new firmware installed in the internal microcontroller, and to our new back cover window, designed by ourselves and produced with 3D printing.

What are the differences between a geiger pancake tube and an ordinary tube

Il Pancake Geiger Muller Tube unlike ordinary geiger tubes, It has a large circular active surface on its upper side, consisting of a special membrane in very thin not that makes it easily crossed by any ionizing radiation, including the least energy.

So this membrane is made of mica, being extremely thin, it can be easily penetrated by radiation with non-negligible mass, like ALPHA particles, made up of 2 protons and 2 neutrons, (in practice HELIUM nuclei), and in general by any other low energy ionizing radiation.

Technical characteristics of the New Firmware installed in the internal microprocessor of the instrument.

• Display of measurements with large digits, ideal for field applications.
• Multiple units of measurement: Sievert, rem, cpm (counts per minute), cps (counts per second).
• Configurable average for running surveys.
• Offline and real-time data logging with data compression.
• Compatibility with data logging software [GeigerLog](https://github.com/Gissio/geigerlog-radpro).
• Configurable pulse indication with optional threshold: click pulses (worn out, silent, forte), LED pulses (on supported devices), display flashes (on display in sleep mode) and tactile impulses (on supported devices).
• Dead time measurement.
• Customizable Geiger-Müller tube settings: conversion factor, average of the instantaneous speed (fast adaptive, adaptive precision, 60 seconds, 30 seconds and 10 seconds), dead time compensation, background compensation, High voltage generator PWM frequency and duty cycle (on supported devices).
• Pipe failure alarm.
• Anti-aliased text rendering on color displays.

In summary why buy it

We encourage you to purchase our GC enhanced geiger counter-01 / PNK, for its high performance due to the new highly sensitive Pancake probe mounted on a new windowed rear cover, and its new firmware with better graphics and several advanced features. Without any doubt we can say that our GC01 /PNK can boast performances that are often much superior to other instruments in the same price range, perhaps advertised as Professional Geiger.

General characteristics:

• Easily detects X-rays, Alfa rays, Beta e Gamma.
• Dose rate in: Sievert, Rem, Counts per Second (CPS), Counts per minute (CPM).
• Calculation of Accumulated Dose in µSievert.
• Interface in Italian and English (on request), easy to use and rational.
• 3 kinds of combined alarm mode selection: light/vibration/sound.
• Visual indication of radioactive particles with red LED.
• Real-time visual indication of radioactive particles with Ticker or Beeper.
• Real-time clock display.
• It is possible to set the alarm threshold of the accumulated dose.
• Built-in 1200mAh lithium polymer battery
• Type of probe used for detecting radioactivity: Tubo geiger made in USA Pancake ultra sensibile, model: LND-7317, with rear cladding made of thick metal and large front window made of very thin mica. It is filled with a mixture of noble gases + halogens. It is mounted internally to the same instrument with a visible sensitive part. therefore it can easily detect even low-energy nuclear radiation.
