NT8280 Pump suction Electrostatic Radon Meter

NT8280 Pump suction Electrostatic Radon MeterComply with the measurement principles and requirements of GB50325-2020 "Code for Indoor Environmental Pollution Control of Civil Building Engineering" and HJ 12122021 "Measurement Methods for Radon in Environmental Air". It can be used for monitoring and analyzing radon concentrations in ambient air, soil, and water, radiation protection, nuclear accident monitoring, radiation dose evaluation, earthquake prediction, and teaching in colleges and universities.

Features:

❐ It can measure the concentration of radon in the ambient air, water, and soil, as well as the radon release rate on the soil surface;

❐ Portable, small in size, light in weight, suitable for outdoor movement or fixed-point sampling;

7-inch TFT color LCD display screen, capable of multi parameter human-computer interaction, user-friendly interface, and easy operation;

High sensitivity, capable of measuring lower radon concentrations; When the radon concentration exceeds the set limit, an automatic alarm can be triggered;

❐ Dual use for AC and DC, with automatic backlight power-saving function to reduce power consumption;

Equipped with a lithium-ion rechargeable battery, it can support continuous operation of the instrument for 48 hours, making it convenient for long-term mobile measurement;

❐ It can automatically calculate the radon concentration of a single measurement/the average radon concentration of continuous measurements, and automatically save the measurement results;

Real time display of measurement status parameters such as measurement time and battery level;

The instrument is equipped with a built-in printer, which can view and print measurement results at any time;

❐ Optional accessories for measuring soil, water, and radon release rates.
