Strict requirements and detection needs call for security checkpoints to perform efficiently even under very challenging conditions. Choosing the right metal detector is essential. Key considerations include identifying: the size and composition of the items to detect (Security Level), items and levels of personal effects to ignore (Discrimination), the number of people that will be passing through the checkpoint (Throughput). These characteristics must even be obtained in environments with electrical and mechanical noise, therefore the walk-through metal detector must present excellent immunity (Immunity). The PMD2 Plus/EZHD is ideal for outdoor events or checkpoint locations that move frequently and features tool-free installation, weather-resistant protection (IP 65) and ease of system use for screening personnel.
