- Tritium in Air Monitors (Portable and Fixed)
- Tritium Area, Stack, and Nuclear Power Plant Monitors
- Ultra-Sensitive Gas Proportional Tritium Monitors
- Tritium Process and Glovebox Monitors (including for tritium removal, storage beds, recovery systems, accelerators, and reactors)
- Tritium in Water and Tritium in Seawater Monitors
- Passive Tritium/C-14 Air Samplers (Bubblers)
- Tritium Surface Contamination Monitors
- Tritium Calibration Equipment
- Radon Air Monitor
Each instrument is available with a wide variety of features to meet your specific requirements and includes a calibration certificate traceable to NIST. We offer annual tritium gas calibration and repair services at our factory and also provide tritium calibration equipment so that you can calibrate the equipment on-site.
Overhoff Technology has gained an outstanding reputation for having tritium monitors that excel in performance, reliability, and are reasonably priced. Our experience in producing hundreds of different types of monitors for different users allows you to benefit from the company’s design expertise and economical production methods. Overhoff tritium monitors are used worldwide in nuclear power plants, nuclear research and pharmaceutical laboratories, military and government applications, and industrial manufacturing.
We are proud that all Overhoff Technology instruments are made in the USA under an ISO-9001:2015 quality management system.

Tritium Monitoring Instrumentation
With over 49 years of experience, we offer the most comprehensive and reliable selection of tritium monitors available.
Overhoff offers a wide selection of portable tritium monitors which vary in ionization detector volume, sensitivity, and response time.
Dual 200cc ionization chambers, Sensitivity: 10 µCi/m3 (0.5 MBq/m3), 5 second response time
Quadruple 200cc ionization chambers, Sensitivity: 2 µCi/m3 (0.1 MBq/m3), 30 second response time
Dual 1400cc ionization chambers, Sensitivity: 1 µCi/m3 (0.05 MBq/m3), 60 second response time
Overhoff offers both fixed and modular configuration stationary tritium monitors with a wide variety of detectors, electronics, and options to suit any application, measuring all the way from 0.01 µCi/m3 (1 kBq/m3) to pure tritium.
- Room and Area Monitoring
- Stack and Effluent Monitoring
- Process and Glovebox Monitoring
- Ultra-Low-Level Tritium Air Monitoring with Gas Proportional Detectors, Sensitivity: 0.01 µCi/m3 (1 kBq/m3)
- Tritium in Water Monitoring (desalination, effluents, drinking water, seawater)
- Air monitors can also be configured to measure C-14.
Passively collect tritium (HT, HTO) and/or C-14 (CO, CO2) in our high-quality, reliable air samplers. Includes electronic mass flow control, thermal oxidizer, elapsed time indicator, two sample collector manifolds with cascaded collection vials for HT and HTO, and an optional C-14 collection panel consisting of desiccant drying columns and a solid NaOH sample collection medium for C-14.
Overhoff offers NIST traceable tritium gas calibration services at our factory.
Alternatively, customers can purchase the equipment necessary to calibrate Overhoff tritium in air monitors on-site, including:
- Tritium Gas Calibration Standard: Lecture bottle containing <1mCi of tritium calibration gas.
- Tritium Gas Calibrator, includes all the hardware needed for gas calibration (regulator, gauges, and valves)
- Calibration Resistor: Certified to 1% precision, used for electrical calibration or verification. Useful for calibrating at higher ranges.
