Description


Application Fields

Geological prospecting by measuring radon concentration in soil or water. and it can also be applied in areas such as soil radon detection in construction engineering, locating underground water sources, earthquake forecasting, radiation protection, and teaching, etc.


Instrument Characteristics

* RaA instant radon measurement method, short time and high efficiency.

* PIPS detector, with high resolution and real-time display of energy spectrum.

* Automatic tape changing design, no need for manual replacement, support rewinding and repeated sampling.

* Separation design of chamber and detection, with no detector contamination and interference from thoron gas.

* Intelligent switching of gas pipeline for soil radon measurement, no need for manual plug and unplug.

* Constant flow sampling, with accurate and stable gas sampling rate.

* Industrial-grade large-capacity storage chip, with more than 100,000 safe erasures and writes.

* Data Transfer: USB, Mobile APP, Bluetooth printing.

* Small size, light weight, easy to carry.

* Low power consumption, AC/DC double use.

* Support firmware upgrade, easy to maintain.
