Overhoff Overview Features: Stores all instrument data to a database (Microsoft Access) at user-definable intervals Displays all instrument data in table and graphical form (summary and real-time) Limit checks incoming data of all types; each instrument can have its own set of limits of desire Displays over limit or alarm status to security personnel at a terminal and sends email/phone alerts Generates reports on stored data: shift reports, or daily, weekly, and monthly reports can all be generated automatically and in hardcopy.  Graphs can also be included Identifies upward or downward trends in data Identifies non-transmitting instruments Tracks maintenance due on instruments and tracks locations of all instruments within your facility Displays video/images from webcams   Overhoff Overview is a customizable software package for networking multiple Overhoff instruments together or modeling a facility graphically in a series of views. more info:  https://overhoff.com

OTC has designed and built ionization chambers of many different sizes and configurations, each of which was optimized for a specific application, from measuring low-levels of tritium in room, stack, and effluent air monitoring applications to measuring high-concentrations of tritiumin glove boxes, fusion reactors, nuclear pharmacies, process piping, storage beds, and recovery systems, as well as challenging environments such as nuclear power plants.  OTC ionization chambers span all sensitivities, from 10 -7   Ci/m 3   to pure tritium, and can also be used to selectively measure tritium, or only its oxide, even in the presence of other radioactive gases.  OTC ionization chambers are designed for easy assembly and maintenance.  Ionization Chambers: An ionization chamber is an electrically closed vessel containing an internal electrode.  An electrical field is applied between the wall of the chamber and the electrode so that the ionization produced by radiat...

  Model RnCAM Features: Dynamic Range: 0.1 to 2,000 pCi/L Sensitivity: 0.45 CPM per pCi/L Rugged weatherproof housing design suitable for outdoor use Detects radon-220 and radon-222 alpha Full temperature compensation from -20 °C to +50 °C RS-232 output (LAN optional) Microprocessor controlled electronics with non-volatile memory Description: The Overhoff Radon Monitor is a hand-held portable instrument that measures airborne radon-222 and radon-220 over a wide range of concentrations with a very fast response time and excellent sensitivity.  This radon monitor is useful to those individuals who need to quickly establish radon background levels, demonstrate compliance with local regulations, or for radon mitigation efforts.  A large 300cc ionization chamber detector is used to measure below the US EPA’s recommended radon mitigation limit of 4 pCi/L in as little as a few minutes. The Overhoff Radon Monitor can log 40,000 data points to accurately establish the daily varia...
