Application

Tyne Engineering’s new handheld Tritium Monitor is designed to exacting quality standards to meet Tritium-In-Air monitoring requirements. It is a robust, portable instrument that uses all the latest technology.

Features

• Only one operating switch with four settings: Off,Sample, Pump, Set Up.

• Gamma Compensation is achieved with four large ion chambers arranged in a cruciform configuration. Two chambers are used for measuring the air sample, and two are for compensation.

• Less than 10% inaccuracy in 20 mR/hr field

• High Sensitivity. The volume of a measured charge is 500 cc. The current amplification circuit employs ultra-low leakage technology. Each chamber has its individual amplifier, increasing the Signal-Noise Ratio of the analog circuit.

• Sensitivity is 1μCi/m³.

• Radon compensation is provided by the analog filter circuit designed to separate the radon spike.The software can distinguish the radon spike from the tritium signal occuring as a slow-change signal.

• Ion-traps are built into each ion chamber.

• Noble gas compensation is accomplished by interposing a desiccant cartridge between the ports of the measurement and compensation chambers. The airflow to and from these chambers is channeled through ports that are accessible from the

instrument's faceplate. The noble gas signal can be displayed by the micro-processor.

• Direct gamma measurement is provided using an installed GM tube.

• Decontamination by purging of all 4 ion chambers can be achieved with use of the centrally installed cartridge heater.
