I.O.T technology. it is part of our Geiger Counter.
Guardian Ray Smart EXP with reliable external Pancake probe, represents an unprecedented revolution for this category of professional Geiger counters. Thanks to the use of so-called technology: Internet of Things”, (IOT) today it also works in mode “online”, being able to publish the radioactivity data detected in the Cloud in real time. 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.
Guardian Ray Smart 7317 EXP, can connect to the internet to send radioactivity measurements in real time to our free Cloud.
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.
What are cloud servers and how are they used.
In practice they are web servers that acquire and make data available via the internet. In particular, our clouds have been specifically programmed for the acquisition of radioactivity data that are transmitted online from our Geiger counters and also for their publication in almost real time on specific web pages.. For example, thanks to these characteristics 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.
Local storage mode of radioactivity data on microSD.
Our Geiger Counter allows you to store radiation data detected even locally on traditional microSD cards, which despite their very small dimensions allow practically unlimited storage capacity .
Bluetooth connectivity to transmit real-time Radioactivity data to Android devices.
the availability of Bluetooth connectivity allows Guardian Ray Smart to be able to transmit radioactivity data to Android devices which can be viewed in real time via a simple and intuitive specialized software application developed by us.
Simultaneous display of various parameters and multiple units of measurement.
Guardian Ray Smart EXP can also show the radioactive activity on its large color LCD display, indicating it simultaneously in 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.
Guardian Ray Smart EXP is very simple to use thanks to its large 2.8 inch color touch display
E’ the obsolete membrane keyboard has now disappeared and has been replaced by a modern display “touch” color with active matrix, which in this specific model is 2.8 inches, readable even outdoors in the presence of sunlight, which makes the user experience easy and immediate.
Guardian Ray Smart 7317 EXP, It has a super sensitive American-made Geiger Muller Pancake Probe
Also the version “SMART” has a particular Geiger Muller type probe installed internally “Pancake” LND 7317, which in addition to being particularly 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 on request with Accredia calibration certificate.
The exceptional precision and reliability characteristics of our Geiger Counter, they can also be certified at an important national certified calibration center “ACCREDIA” 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 the Guardian Ray Smart 7317 as the best Geiger Counter ever produced in Italy.
Who is the Guardian Ray Smart 7317 EXP recommended for?? ?
Due to its professional characteristics, our new radioactivity meter is recommended to 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.
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 Bluetooth e 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.
It also integrates a software-controlled clock unit with date display that updates automatically when the instrument is connected to the internet.
the acoustic function can be silenced as desired and also visual, which in practice makes the LED located on the front panel of the instrument flash and which uses an acoustic transducer, it also emits an audible click for each ionizing particle detected. Furthermore, the same transducer can also play constantly at a high volume if a certain radioactivity threshold that can be set as desired is exceeded.
the USB interface in this model which however is used exclusively for charging the internal lithium ion battery.
