The RDS-31TD multi-purpose survey training meter simulates gamma radiation surveying using active “live” TWR Source(s). Built with OEM hardware, simulator looks, feels and operates with most functions supported – identical to a RDS-31 survey meter. Supports OEM WRM2 radio for wireless remote monitoring. Configurable units and audible, visual and vibration alarm. Instill the experience, self-assurance and real understanding you want your trainees to achieve – safely.
