. Product Introduction

The TAM series of Tritium Air Monitors are comprised of mains unit and ionization chambers. Main unit is a SCM System based on 8031 sing chip system. These Tritium Air Monitors are designed to have a wide variety of features, including automatic control, automatic zero setting, multi-parameter display, data monitoring, processing and storage, and warning and communication. By employing modular design, this series of Monitors provide optional installation and combination suitable for automatic continuous air monitoring for the presence of tritium in the environment, glove box at nuclear facilities, highly radioactive noble gases and in a wide range of situations.
