Guardian Ray Smart 2.8p Professional Geiger Counter with WiFi, Bluetooth, microSD, Touch Color LCD and Pancake probe.

6 Tools in one: WiFi Geiger Counter & Bluetooth, Rate meter, Http Client, TCP Client, Radioactivity Dosimeter and Datalogger on microSD.

Finally after a year of hard work we are happy to present the new edition “SMART” by Guardian Ray with Pancake probe, the new born of Italian ingenuity and creativity. This new Geiger detector basically represents the natural evolution of the previous series ” Plus”.

I.O.T technology. it is also in our Geiger Counter.

Guardian Ray Smart con sonda pancake, represents an unprecedented revolution for this category of Geiger counters. Thanks to the use of so-called technology: Internet of Things”, (IOT) it could become “online” with full rights. For those who don't know, per “Internet of Things” refers to the devices, instruments, installations, system, machines and tools that can be interconnected to the network and exchange information through it. These devices are essentially the basis of the Internet of Things and are also defined as smart objects.

Guardian Ray has become “Smart”

In the specific case we are referring to the possibility of connecting our instrument via its integrated WiFi module to any local network and also to the internet. Once this is connected to the network it will be possible to automatically update the system date and time and above all upload the radioactivity data to the Clouds made available by the manufacturer or even owned by the customer himself.

How cloud servers are used by our Geiger

In practice they are web servers which in this specific case have been programmed to acquire the data on radioactivity sent to the network by our instruments and for their automatic publication in real time on specific web pages.. For example, it would be possible to use our Geiger counter also as a real control unit for the constant monitoring of radioactivity levels.You can click on the link or image below to immediately view the environmental radioactivity data detected by our Geiger in real time in our laboratory in Quartu Sant'Elena (Cagliari).We would like to point out that Guardian Ray Smart also supports double WiFi configuration, that is, it can function as a Client or as an Access Point.

Other ways of storing radioactivity data

Our Geiger Counter allows you to store data collected locally, which will now no longer be allocated to the internal memory, as happened in previous models, instead they will be automatically saved on very practical microSD cards, which despite their very small dimensions allow practically unlimited storage capacity .Guardian Ray Smart It can show radioactive activity on the large color display by simultaneously translating it into different units of measurement, that is to say: in microSievert/h, in interRontgen/h, in CPM o in alternativa in CPS, while at the same time it calculates and displays the dose of ionizing radiation to which one is exposed over time.It also works like a real one “Rate-Meter”, allowing in this special mode the execution of very precise measurements with fixed acquisition times, presettable from a minimum of 60 to a maximum of 10,000 seconds.

The approach is simple and intuitive thanks to the color Touch display

It disappears “old” membrane keyboard which is now replaced by a modern display “touch” with active color matrix, which in this specific model is 2.8 inches. Guardian Ray Smart con Pancake, it can also be requested in the variant “Deluxe” with 3.2 inch display.Also the version “SMART” has a particular Geiger Muller type probe installed internally “Pancake”, which in addition to being very sensitive and precise, It has the interesting characteristic of being able to detect all types of ionized radiation, that is to say: the Alphas, And Beta, Gamma and X Rays.This clearly differs from normal Geiger tubes due to its large active surface made up of a thin mica membrane with a diameter of 45 mm.. Therefore it is also permeable to Alpha radiation, which due to their corpuscular nature cannot be detected with common probes with metal or borosilicate casing.

Also available with Accredia calibration certificate.

The excellent characteristics of this radioactivity meter can be certified at a major certified national calibration center “ACCREDIA” of our trust valid for the purposes permitted by law. The results of these checks, which we have already had performed in previous series, from which this new model derives, they attest without any uncertainty to the excellence of the performances. Therefore we have no problem defining this new model in the series as one of the best Geiger counters ever produced.

Main features:

Professional Geiger Counter Product, sold, guaranteed and assisted in Italy by the same national manufacturer.Guardian Ray Smart takes advantage of a new and powerful 32-bit microprocessor with form WiFi a 2.4 GHZ integrated and has a multitude of software functions for the acquisition and processing of radioactivity data. among these we mention: the function Radioactivity dosimeter, which automatically calculates the overall radiation dose to which you are exposed in a given period of time, the function: Rate meter, that is, a special measurement mode that significantly increases the sensitivity and precision of acquisition by lengthening the measurement sampling times.Regarding the hardware, it has a software-controlled clock unit with date display that updates automatically when the instrument is connected to the internet, ha the rechargeable lithium battery yes 3.7V, and a broad display Touch, 2.8 backlit″ coloured with active matrix, perfectly readable even outside in the presence of sunlight.E’ also present a buzzer which can be enabled and disabled at will and which emits a “beep” for each particle detected, but it can ring insistently if a certain radiation threshold that can be preset at will is exceeded.The USB interface is not missing but in this model it is used exclusively for charging the internal lithium ion battery.

Who might need our Geiger Counter ?

Due to its professional characteristics, our new radioactivity meter is recommended for qualified radiation protection experts, to public administrations such as municipalities, the local health authorities for the protection of citizens' health and of course the police to conduct health investigations directly in the area.We think it could also be useful in research and analysis laboratories, and in particular to companies that import and process products from countries that have been involved in serious nuclear accidents in the past.In practice, anyone who needs to have a multifunctional radioactivity detector could purchase it, modern, precise and reliable, capable of ascertaining with sufficient precision the levels of ionizing radiation present in the environment, in the ground, in building materials, on some foodstuffs and in general on any product or personal object.
