Multi-Room Tritium-in-Air Monitor

Model: 7042


Tyne's Multi-Room Tritium-in-Air Monitor is a device which simultaneously monitors up to 32 remote locations or rooms for background (environmental, gamma, other isotopes) compensated tritium activity. It is suitable for use in Nuclear Power Stations, Tritium Extraction Plants, Laboratories, or any location where tritium contamination may be a possibility.

The Multi Room Tritium in Air Monitor is designed to monitor up to 32 separate rooms for tritium. The system will automatically step through a user selectable sequence of room measurements with a minimum required measurement time of 2 minutes. The system uses a zero maintenance drier with dew point measurements to calculate the background contribution from gamma radiation, other radio nuclides and any offsets from the total signal ensuring that the system only measures the amount of tritium in the HTO form. With the computer control, automatic filter cleaning and zero maintenance drier the system does not require any attention through out the year of operation. All data is logged and charted and can be accessed remotely by health physics. This high tech solution for multi room tritium in air monitoring ensures that all data is recorded without any human errors involved. This system is the perfect cost effective solution for large facilities.

The entire system is housed in a compact, attractive kiosk cabinet shown in the picture. The cabinet is made of strong 12 and 14 guage steel and its attractive 2-tone paint is durable baked-on powder coating.
