QAL 181 QAL 1 APPROVED PARTICULATE MEASUREMENT SYSTEM ■ Forward-scatter technology with a minimum detection limit of <0.05 mg/m3 ■ ProScatter™ technology provides enhanced measurement due to reduced cross-sensitivity to particle type and size compared to other scatter monitors ■ Robust and rugged for challenging high-temperature 500°C stack conditions and Ex hazardous zones - Automatic zero and span checks that fully challenge the system's ability to measure forward-scattered light and satisfy daily drift checks . TCP/IP Ethernet, RS485, RS232, 4x4 - 20 mA outputs, 1x 4-20 mA input, 4x Relay outputs, 1x Relay input for increased choice of integration with your DCS or DAHS (controller specific).
