Testermeter- FYJL-B170 αβ surface contamination measuring instrument
Introduction of instrument
| FYJL-B170 surface contamination measuring instrument is a portable surface contamination measuring instrument. The instrument uses a large-area ZnS+ plastic scintillator dual crystal detector, which can measure α and β at the same time. It is mainly used to detect surface contamination of the ground, desktop and other surfaces in radioactive workplaces, as well as contamination of the hands, shoes, work clothes and other surfaces of the staff. The instrument uses a replaceable rechargeable lithium battery, a 3.5-inch wide-viewing angle IPS high-brightness LCD display, and a multi-button design, which is simple to operate and easy to use. |
Features
1. Can measure α/β/γ simultaneously, or measure α/β/γ separately, and switch with shortcut keys; 2 Can freely edit the added nuclide library, can freely add nuclides, and can add up to 45 nuclides; 3 Can freely choose to deduct or not deduct background, and the background measurement time is optional; 4 Sound and light alarm and LCD indication alarm; Functional characteristics 5 Can store no less than 10,000 groups of data, with power-off protection function; Support USB and wireless data transmission modes (wireless mode is optional). |
