Below you will find New Products released by Overhoff Technology.

Tritium and Carbon 14 In Air Sample Collecting System

The NEW TASC is a small self-contained unit which serves to collect samples from stacks, hoods, room air, the outside environment or other areas. TASC consist of a Pump, Mass Flow Controller, regulated Thermal Oxidizer, and 2 Digital Displays, which display the airflow rate and oxidizing temperature.

Radon Monitor

The Overhoff Radon Monitor is intended to measure radon-222 and radon-220 over a wide range of concentrations. The radon monitor is useful to those individuals who need to establish radon background levels or demonstrate compliance with regulations and to those individuals involved in radon mitigation efforts. The radon monitor can log 40,000 data points to accurately establish the daily variation in radon concentrations.

The radon monitor’s internal rechargeable battery can operate the monitor for 24 hours. By using the AC/DC adapter the monitoring time can be extended indefinitely which allows for logging the variations in radon concentrations due to the environmental effects of changes in barometric pressure and rainfall.

The radon monitor is very useful as a real-time radon monitor for those individuals involved in radon mitigation since the real-time indication gives an immediate indication of any mitigation efforts. Mitigation of radon concentrations can be as simple as a change in ventilation flow or a more complex effort such as installing a vapor barrier.

Xenon Separation Panel

New Product from Overhoff Technology Corporation enables precise measurement of tritium in the presence of noble and other radioactive gases. The separator extracts the tritium oxide component of a continuous air sample, which may also contain Xenon, Krypton-85, Carbon 14, or other radioactive gases. The tritium only output airflow is then connected to an external tritium monitor, for an accurate tritium only measurement.

2x200-LD Tritium Leak Detector

The Overhoff Model 2×200-LD Tritium Leak Detector has the unique ability to monitor for tritium compounds and elemental tritium in real time while providing gamma compensation. The two measurement channels, T2 and T2O/HTO, are selected with a front panel toggle switch and appear on a single digital display.

The required radiological protection for tritium compounds is much higher than that for elemental tritium. Elemental tritium will combine readily with oxygen to form tritium oxide and also will replace hydrogen atoms in compounds. Therefore the presence of elemental tritium in the working environment is an indication of a leak in the system or container. Knowing this, the user of the Model 2×200-LD can rapidly locate the point of release and more efficiently secure the source of leakage.

Overhoff OverView

Overhoff OverView software is an affordable means to provide centralized radiation and environmental monitoring for your entire area or facility. Whether it is a single building, or many square miles of buildings, OverView is an easy-to-use, off-the-shelf solution that formerly was only achievable with expensive, complicated, or custom software.

OverView accepts and databases data from networked radiation detectors, environmental monitors, and web cams, and allows you to view and generate reports on the data. OverView can also track maintenance due on instruments. OverView will give you and your personnel a complete view of radiation monitoring at your facility, a recording of the past, a clear vision of the present, and a means to predict and control the future.
