New Infrared Version of Signet Turbidimeter

GF Piping Systems (UK) has added the new Signet 4150 Turbidimeter to its extensive line of analytical instrumentation. The new instrument provides accurate and reliable water quality monitoring that in two-versions is
compliant to either ISO 7027 or U.S. EPA 180.1 making it ideal for both municipal and industrial applications. With its integral pressure regulator, the 4150 features easy single unit installation and setup. Typical applications include monitoring distribution of potable water, raw or filtered water, wastewater reclamation effluent, and aquatic life support systems.

Turbidity measurement in the 4150 is accomplished with 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 dry stable environment for accurate measurement and a built-in backpressure valve can be adjusted to eliminate bubbles that may cause erroneous reading. Available in two measurement ranges, the 0-100 NTU/FNU unit is intended for low range applications such as potable water. The 0-1000 NTU/FNU unit can be used for higher range applications such as raw water and wastewater
reclamation.

Not requiring that the instrument be taken offline, calibration can be completed easily in less than five minutes. The premixed stable standards allow for multiple system calibrations without chemical mixing. After calibration, the 4150 can be back on-line once the measuring glass cuvette is placed back 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 more affordable,” points out James Chandler, GF Piping Systems Product Manager.

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

” Other features of the 4150 include sensing humidity levels and displaying a desiccant replacement warning and cleaning required indicator, a fully spannable 4-20 mA output signal, two user programmable alarm relays, and a bright backlit display for easy reading. The ultrasonic cleaning option provides for a more accurate and extended on-line measurement.
