RTM 2200 Soil Gas - Radon and Thoron plus Soil Permeability Monitor

RTM 2200 Soil Gas – Radon and Thoron Monitor with Integrated Measurement of the Soil Permeability

🚚 FREE SHIPPING on online orders over € 200 (Inside EU). Orders below € 199 depend on the final destination.

The new RTM 2200 is the ultimate tool for a quick, accurate, and reliable in situ radon soil gas measurement (EN ISO 11665-11) by a single keystroke. The implemented sampling cycle covers the determination of the soil permeability as well as the chamber flushing with fresh air at the end of the measurement. A water inlet protection switches off the pump in case of accidentally sucking of groundwater. The integrated GPS receiver makes the later mapping of sampling points easy.

The principle of real alpha spectroscopy over the entire measurement range makes the instrument the first choice for soil gas measurements.

Description

The advantages in overview:

Fastest possible response and decay time; no delay times
No interference by thoron (Rn-220 – will be measured separately)
No long term contamination by Po-210 even at permanent measurements at high radon concentrations

The unit comes in a very robust and handy case for use in harsh environmental conditions. A signal light at the top of the case indicates the end of a measurement or warns in case of very low soil permeability.
The powerful software dVISION provides all functions for data management including the display of results in the integrated map (Google™ based) as well as the export to CSV or KML files.
Of course, all functions required for typical applications (long- and short-term measurements, searching for entry paths, radon in water, or radon exhalation) are implemented in the RTM 2200.

Additional options:

TDR probe for simultaneous measurement of the soil moisture as another important parameter for the evaluation of the radon potential
Blower door kit: contains a high-precision and long-term stable differential pressure sensor for very small pressure drops (range 0 … 25 Pa) to measure pressure differences between individual rooms. This function is necessary to investigate radon transportation in buildings
Sensors for CO₂ and CH₄ integrated in the internal air loop
