This unit continuously monitors two operators and two ground connections independently, with it's patented resistance loop monitoring technology. It is able to maintain two work operators and two surfaces at the same time to eliminate the risk of ESD damage from undetected wrist strap assembly failures. It has independent safe lights for each operator and each ground connection allowing operator to visibly see status of each operator and mat. Operator will be able to see alarm if noise level is high, or in contrast, able to hear the alarm without looking at the monitor.
