Model PM1703M

Model PM1703M (PRD)Gamma Personal Radiation Detector

The PM1703M is the latest generation in radiation detection for non-technical personnel. In the event of a radiological emergency, first response team members equipped with a PM1703M can immediately survey a large area for any radiological presence because of a dramatic improvement in detector sensitivity and response time. The instrument discreetly detect radiation and alert the operator through a vibration or audible alarm. Ease of use, sensitivity. and durability under harsh environmental conditions make the PM1703M essential for those who work in emergency services, hazardous materials, counter-terrorism, border patrol, law enforcement, military, or medical and industrial applications.

The PM1703M offers two critical operation modes: the first mode incorporates a 1-9 strength indicator scale for simple analysis of sources present and the second mode provides exposure rate readings and accumulated dose information commonly found in dosimeters. The instrument employs an algorithm which enables the user to adjust the settings to minimize false alarms in high background level environments without compromising the probability of detecting a source.

This model has a belt clip and bright visual display which promotes hands-free operation. The shock resistant housing provides a watertight, robust monitoring tool for the most demanding emergency response applications. Tests have shown the PM1703M is more sensitive and responsive than commonly used first responder meters. Data—including the alarm event and time, and level of alarm exceedance relative to the preset threshold—for up to 1000 incident histories may be stored in the non-volatile memory of this instrument. All of this data may be transmitted to a PC through the IR channel for processing, analysis, and control.
