Radon Measuring Instrument With High Sensitivity, Easy To Use And USB Transmission Interface FJ-2500
Overview
The FJ-2500 radon meter is used in environmental monitoring, sanitation, construction engineering, home improvement, geological prospecting, seismic monitoring, scientific research and other fields. Used to detect radon in the air, radon in the soil, radon in water and radon extraction rate. The instrument complies with the measurement principles and requirements of GB50325-2001 "Code for Indoor Environmental Pollution Control of Civil Construction Engineering" and GB/T16147-1995 "Measurement Method of Scintillation Bottle for Radon Concentration in Air".
Feature
Small size, light weight, easy to carry
Human-computer interaction interface, convenient operation
High sensitivity, low power consumption,using the most classic scintillation radon method
USB data transmission interface, TCP/IP, RS485, RS232, industrial wireless communication methods are available
