Viscosity, pH, and temperature controller

DEVEL NEW EQUIPMENT, PROCESSES, Viscosity, pH, and Temperature Controller Norcross Cop Newton, Mass. A new controller available from Norcross Corp. displays viscosity, pH, and temperature for coatings applications. The controller provides a con-

venient display of multiple parameters that are used to monitor and control viscosity, pH, or temperature for either single stations or for multiple-station systems. Circle 401 on reader information card

Decorative Chrome Plating Process Taskem Inc. Cleveland Taskem Inc. announces the introduction of a high-performance, singlecell technology for decorative trivalent chrome plating, the TriStar TC Process. The TriStar TC Process allows the TriStar TC deposit to resemble the color of the deposit from decorative hexavalent chrome electrolytes. An additional benefit is Taskem’s Ion Exchange Technology, which was developed specifically for the TriStar TC METAL FINISHING . MARCH 1995

& MATERIALS

Process. This form of purification allows for rapid removal of copper, zinc, iron, and nickel. Compared to other proprietary trivalent chrome processes, the process operates at slightly elevated temperatures, which allows for some return of drag-out losses and significantly reduces the volume of sludge that must be disposed of.

hard-water areas. When mixed with sodium hydroxide, Clean-R 90X removes drawing compounds, cutting oils, stamping oils, and shop dirt. No special equipment is needed, although an oil skimmer or tank separator is necessary to remove the split oils and increase bath life. Controllers are available to make additions to solutions through conductivity metering.

Coating Thickness Gauge Elcometer Inc. Rochester Hills, Mich.

Ion Exchange System Birchwood Casey Eden Prairie, Minn.

The Elcometer 355 portable coating thickness gauge incorporates a twopart combination of a host instrument and a probe module. Through this system, true +I % accuracy is achieved.

An improved and expanded Ion Exchange System from Birchwood Casey is designed to remove dissolved ions and solid particulate material from mocess rinsewaters in metal-finishing

The host instrument is available in two versions-14 key (standard) and 28 key (top) options. The 14 key standard unit provides memory to 5,000 readings, autobatching of data, and simple statistical information. pe 28 key top unit can retain 10,000 readings in batches, has full statistical capability including average and counted modes, and comes with calendar and clock functions.

Liquid-Soak Cleaner Pave0 Inc. Cleveland Pavco Inc. announces the development of Clean-R 90X, a liquid-soak cleaner concentrate for steels and stainless steels that is safer than powdered cleaners and formulated to work in

systems. The system allows the user to operate a variety of metal-finishing processes while keeping drains at a zero discharge level. The primary benefit is that the system’s rinse tanks can be disconnected from the drain, resulting in an upgrading from probable low-level discharge to certain zero discharge of hazardous materials to the drain.
