The AV410 is a single-input, low-range dissolved organics monitor designed for potable water treatment plants, measuring dissolved organic carbon from 0 to 20 mg/L C. It uses UV absorption at 254 nm with automatic turbidity compensation at 400 nm and reagentless operation to minimize maintenance and operational costs. The sensor includes a programmable automatic cleaning system and a lamp rated for 1.2 × 10⁹ flashes, achieving 13% of its rated life over 10 years of typical use. The transmitter includes two isolated 0-20 mA current outputs, three programmable relay outputs, and a dual 4-1/2-digit LCD display with auto-off backlight. It operates from 100 to 240 V AC and meets IP65 ingress protection with CE marking and UL safety approval. The sensor is wall-mountable with dimensions of 327 mm wide × 410 mm high × 162 mm deep and weighs 6 kg.
AV410 single-channel UV254 low-level dissolved organics monitors (0 to 20 mg-1C) are designed for use on potable water treatment plants. In particular, they can be used to monitor the quality of the outlet from sand and carbon filters to provide a THM precursor measurement.
Long term field trials have shown that maintenance demands on these applications are minimal.
