Professional Geiger Counter Dosimeter SBT-10A Pancake Mica window ECO-1

Description

For sale amazing professional ECO-1 Geiger counter with sbt-10a pancake geiger counter tubes with huge mica window.
Works fast and with high accuracy
In nice used condition.
I tested geiger counter, it works great and looks nice.
Made in 2006 and 2010 year
Set includes:
1) Eco-1 geiger counter
2) charging adapter
3) recharchable battary (just as sample as it need to be changed)
Long charging cable is not included in listing, it is same as to siple computer, printer or so.
As geigers fan can say this one is of high quality and works very fast
will be well packed and shipped by air mail with tracking number
Technical characteristics:
There are 3 measurement ranges:
F - An equivalent doze rate of gamma radiation (detection and estimation the level of the radioactive safety).There are two options of the measurements: “cyclic” and “unitary”.
А - A specific radioactivity (to detect the impurity of water, ground, food, building materials, cargoes by beta and gamma radioactive radionuclides).
В - The flux density of beta particles (to assess the impurity of the surfaces of various subjects, clothes, a body, etc.).
Gamma radiation energy range from 0,015 up to 3,0 MeV.
Beta radiation detection energy is more than 0,15 MeV.
Doze Equivalent measurement range is from 0,10 up to 1000 mkSv/h.
The basic error (Accuracy) 15%.
Specific activity measurement range from 4,0 up to 100 kBk/kg.
Beta particles flux density measurement range from 0,1 - 100 1/(s·cm2).
geiger makes a sound alarm when the measurement ended in each of the operating modes.
In modes of the EDR measurement, the measurement process is accompanied by a specific sound (clicks) which frequency is in proportion to the measured EDR. Exceeding the measured EDR more than the value 0,60 mkSv/h is accompanied by the sound alarm.
Dimensions 180х85х55 mm.
Weight 350 grams.
Power supplie NLZ recharchable battaries - 0,9 or from a network of an alternating current 220V, the frequency 50Hz.
Sound alarm is on when the battaries need to be charged.
Measurement time
EDR measurement mode - 20 sec;
flux density of beta particles measurement mode - 160 sec;
specific activity measurement mode - 1100 sec.
Working temperature -20 up to +50 °С;
Relative humidity +25 °С, up to 95%;
The atmospheric pressure 84 up to 106,7 kPa.
