NT8280 Pump suction Electrostatic Radon Meter

Independent research and development, customizable.

comply withGB50325-2020Code for Indoor Environmental Pollution Control of Civil Building EngineeringHJ 1212—2021The measurement principle and requirements of "Measurement Method 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.

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

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

❐ 7inchTFTColor 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 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 instrument48One hour, convenient for long-term mobile measurement;

❐ Automatically calculate the radon concentration for a single measurement/Continuously measure the average radon concentration and automatically save the measurement results;

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

❐Built in instrumentprinter,Measurement results can be viewed and printed at any time;

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