The GF Piping Systems Signet 9900 Transmitter has a batch controller option and supports multiple parameters that include flow, pH/ORP, conductivity/resistivity, salinity, temperature, pressure, level, and 4-20mA signals, and also batch systems. It has an extra-large auto-sensing backlit display that allows greater visibility, reducing the risk of misreading or misinterpreting the displayed values. The display shows separate lines for units, main and secondary measurements, as well as a dial-type digital bar graph. Designed for complete flexibility, plug-in modules enable the unit to be easily adapted to meet changing customer needs. Its multiparameter capabilities make it ideal for water and wastewater treatment, reverse osmosis, deionization, chemical dosing and delivery, metal and plastic finishing, fume scrubbers, cooling towers, and all types of filtration. 800-854-4090; www.gfps.com.
