GF Piping Systems has added the new Signet 4150 Turbidimeter to its line of analytical instrumentation. The new meter provides accurate and reliable water quality monitoring that is compliant to U.S. EPA 180.1, making it ideal for industrial applications. With its integral pressure regulator, the 4150 features easy one-unit installation and setup. Typical uses include monitoring for potable water distribution, raw or filtered water, wastewater effluent, and aquatic life support. Turbidity measurement on the 4150 is accomplished through a 90 degree light that reflects particles as they flow through the cuvette, providing continuous and accurate on-line measurement. The unit’s replaceable desiccant pack assures a stable environment for accurate measurement and a built-in backpressure valve can be adjusted to eliminate bubbles that may cause reading errors. Available in two measurement ranges, the 0-100 NTU version is intended for low range applications such as potable water. The second, 0-1000 NTU version, can be used for higher range applications such as raw water and wastewater.
