Description
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:
- Replacement for the small and inefficient original Chinese-made Geiger Muller tube, with a high-performance professional Pancake-type Geiger probe, circular shape produced in the USA. The instrument can now detect high-energy Beta and Gamma radiation with extreme sensitivity, even the most critical corpuscular ALFA and less energetic Beta radiations.
- Replacing the original back cover with a new one, equipped with a 46mm diameter circular window with protective grille. This new Cover was specifically designed in CAD to house the new G.M. probe. Pancake. The specially designed circular window of the new Cover. in practice it allows you to expose the active mica surface of the Geiger Pancake Tube, directly outwards, allowing it to easily detect even the less energetic ALFA and Beta radiation.
- Instrumental adjustment and calibration of the high voltage that powers the new Geiger Pancake Tube. It has now been set via software and instrumentally calibrated to the nominal value of 500V, allowing the Geiger Pancake tube to always function with maximum linearity and precision.
- A new customized Open Source Firmware has been installed in the internal microcontroller, now available with menus 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, based on Open source firmware Gissio@RadPro, with many advanced measurement features and a new much more rational graphics.
- New advanced algorithms for a more refined measurement of radioactivity. Il nostro JT-RAD01-7317SW, 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.
- Rechargeable power supply: The RAD01-7317-SW is equipped as standard with an internal 3.7V 1100mAh lithium ion battery and a USB socket which at the moment only serves to be recharged via a PC or a common 220V mains adapter (not provided).
The new features of our upgraded JT-RAD01-7317SW Counter at a glance.
After our intervention, this Geiger Counter has become a perfectly suitable detector also for semi-professional use. Now it is decidedly much more sensitive and precise than most of the well-advertised and even praised as professional low-cost Geiger Counters by the competition.
It can detect even the weakest sources of Alpha radiation with very high efficiency, Beta, Gamma and X -rays, while using different measurement modes that can be set by the user.
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 customized 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 upgraded geiger counter JT-RAD01-7317-SW, for its very high performance and the most convenient price among all products with the same characteristics. Without hesitation we can state that it can boast performances that are often much superior to other instruments in the same price range, perhaps also advertised as Professional Geiger.
