Description
The “GS Ecotest” application and the “Gamma Sapiens” portable radiation detector will turn your smartphone or tablet into the dosimeter!
Website for UKRAINE - http://www.gamma-sapiens.com.ua
INTERNATIONAL website - http://www.ecotestshop.com/dosimeters-and-radiometers/gamma-sapiens
Measurement results are continuously transferred from “Gamma Sapiens” to “GS Ecotest” over the Bluetooth interface. Radiation measurements allow the operation of other smartphone features, such as making and receiving calls, sending and receiving SMS, setting up and using other applications.
Take control of the radiation level around you and monitor the dose accumulated in your body using “Gamma Sapiens” and “GS Ecotest”!
The “GS Ecotest” application provides:
- continuous flow of information about the radiation level and the accumulated dose from the “Gamma Sapiens” detector to the smartphone over the Bluetooth interface in real time;
- display of collected dosimetric information in one of 4 different graphic representations;
- display of collected dosimetric information with GPS coordinates on a map;
- automatic track formation of dosimetric measurements by different user-defined criteria;
- setting of one or more dose and dose rate threshold values that, when exceeded, are followed by light, audio, and vibration alarms actuated on the smartphone;
- storage of necessary dosimetric information (dose and dose rate) in a relational database;
- view of stored dosimetric information in a database within a certain period of time;
- dosimetric measurements exported in .kmz file for viewing on Google Earth and Google Maps, forwarding through the Internet and posting on social networks;
- operation of the detector from the smartphone;
- ability to use the smartphone in a normal mode – making and receiving calls, sending and receiving SMS, setting up and using other applications, etc., without interrupting the process of dosimetric measurement as well as loss of dosimetric data;
- work with other well-known “ECOTEST” TM dosimeters – МKS-05 “ТЕRRА” and RKS-01 “SТОRА-TU”.
The “Gamma Sapiens” detector enables:
- high dynamics and reliability of dosimetric measurement results;
- γ-radiation dose rate measurement in the rage of 0.1-5000 μSv/h;
- γ-radiation accumulated dose measurement in the rage of 0.001-9999 mSv;
- reliable transfer of dosimetric information to the smartphone through the Bluetooth interface at the distance of 5 m;
- wide operating temperature range – from -18°С to +50°С;
- ingress protection rating – ІР30;
- power supply – two ААА batteries;
- dimensions – 19 × 40 × 95 mm;
- weight without batteries – 50 g.

Comments on GS Ecotest for Android

★★★★★ Works with Terra Bluetooth. Would be nice to have additional options, such as to turn on sound with a choice of sound on each count - click or beep. Would be nice to feed time of phone into Terra device
★★★★★ Need a dosimeter This makes sense. But it would be nice if the application listing was a little bit clearer on that
★★★★★ Android 9 users, Before connecting a dosimetry device to the Android device for the first time, in the Bluetooth settings of the Android device specify the Device name: CHECKPOINTx, where x is any letter or digit.
★★★★★ Not sure if my previous review is published, but I want to make a correction to it. The GS has already showed that fish in my favorite restaurant had radiation level slightly higher than background noise by 0.03 units. Normal was 0.08-0.09 units, and the fish was 0.12-0.13 (both measurements at 25% stat error) :)
★★☆☆☆ Does not work. Don't buy The dosimeter does not connect Bluetooth properly. POOR OPERATING INSTRUCTIONS. 2 units of detector both cannot connect when operated according to manuals. Refund process EXTREMELY TROUBLESOME due to shipping back into Lithuania. Was given unusable return shipping method through TNT due to lack of ship back documents
★★☆☆☆ No Radioactive I think it's not work or its no radiation its look like no gamma, if there's has the radiation's zone, i try, I will dead
★★☆☆☆ X-ray room test I've bought this to test the radiation during shots but during track recording the Statistical error keeps jumping to 255% then drops 141% and could not accurately record radiation. Please help.
