NexAlpha-R Radon in water (Installed) and the RnCAM Radon in Air (Installed or portable) FM-9W electronics include one display from the two detectors and computer interface. Water moves through the NexAlpha-R which measures Total Radon. The RnCAM measures Radon in the air. The system removes and cleans Radon from the water via a separator chamber. Radon gas bubbled out of the water and entered the RnCAM air monitor for measurement. The cleaned water is directed out of the separator chamber to the outlet drain. The RnCAM can be detached from the system and used as a portable Radon air monitor.

Down Hole Tritium in Water Monitor. Continuous Real-Time. Measures at or below EPA/DHS PAG Levels. Protective Action Guideline. Five models:

SSS-33-DHC and SSS-33-DHC-4 each will deploy to 160 feet.
SSS-33-DHC utilizes a two-inch diameter well hole.
SSS-33-DHC- 4 utilizes a four-inch diameter well hole.
SSS-33-DH-XT utilizes a two-inch diameter well hole and will deploy 5,000 feet.
SSS-33-DHC-WH and SSS-33-DHC-4-WH utilize the WELL-HEAD (WH) SERIES procedure.

The WELL-HEAD (WH) Series procedure has the same function as the other models, with significantly higher sensitivity and reduced maintenance by the simple expedient of placing only the pump down the hole and bringing the detection cell, filtration, and amplifiers up to the surface where they can sit alongside the readout and data transmission package which was already on the surface at the WELL-HEAD. There are thousands of boreholes in the United States which could be or should be monitored for Tritium.
