GF Piping Systems Expands Analytical Instrumentation Line

New Signet Turbidimeter Featuring Quick and Easy Calibration

TUSTIN, Calif. - Oct. 7, 2008 - GF Piping Systems has added the new Signet 4150 Turbidimeter to its extensive 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 both municipal and 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 which 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.

Without the need for tubing disconnection, calibration can be completed easily in less than five minutes. The inexpensive calibration standard allows for both dry and multiple system calibrations without chemical mixing. After calibration, the 4150 is instantly back on line once the glass cuvette is placed into the measuring chamber.

"What our Turbidimeter offers that others on the market do not is the capability for multiple instrumentation calibration with the same kit, making it much more affordable," points out Dave Vollaire, GF Piping Systems Product Manager.

"And, by not having to take the unit offline for calibration, there is no delay, providing additional time and cost-saving efficiencies."

Other features of the 4150 include a desiccant replacement and cleaning required indicator, a fully programmable 4-20 mA output signal, two programmable alarm relays, and a bright backlit display for easy reading. An ultrasonic cleaning option provides for accurate and extended on-line measurement.
