The ERK-525-3 is a complete portable radiation monitoring system designed to measure a broad range of radioisotope contamination under field conditions. The DSM-525 is a dual probe (connected at the same time) survey meter that measures contamination and dose levels from micro-R to 200 mR/hr plus the kit contains a GP-1003 that can measure gamma up to 10 R/hr. The ERK-525-3 does not require changing probes to obtain the full operational benefits of the system except when using the GP1003 (the probe can be “Hot Swapped); the user needs only to turn the selector switch to the desired probe and the rest of the operation is automatic. The instrument and accessories are contained in a very durable water-resistant carrying case for easy storage and portability.
