Plating Bath Analyzer Asoma Instruments Inc. Austin, Texas

Asoma’s improved Model 6OOT-L on-line plating bath analyzer provides continuous, in-process monitoring of nickel concentrations in electroless baths. Employing the technique of X- ray fluorescence, the analyzer reports nickel concentration by direct observa- tion of the bath as continuously circu- lated through a flow cell. The analysis process is closed-loop and nondestruc- tive, so no waste products are gener- ated; thus, the 6OOT-L’s output can be used to maintain optimal bath stoichi- ometry by controlling automated addi- tions of replenishment concentrates.

Temperature Controllers Bamant Co. Barrington, 111.

Barnant Co.‘s new series of highly accurate, versatile temperature con- trollers features direct plug-in of heating devices and incorporates ad- justable over-temperature and loop- break cutoff for fail-safe operation. Available in both standard and de- luxe models, they are ideal for use in pilot process plants, R&D labs, and for OEM applications. Maximum ac- curacy is kO.4”C. The controllers

provide three different control modes (basic on/off, autotune PID, and pro- grammable PID), field calibration, offset capability to compensate for probe error, and a full range of pro- grammable alarms.

Heavy Metals Removal BetzDearborn Horsham, Pa.

New water treatment technology uses advanced precipitating agents to effectively remove heavy metals from wastewater, reducing treatment costs, permitting more effluent to be recy- cled, and eliminating the environmen- tal problems associated with hazardous waste disposal. MetClear MR metal scavenging products provide consis- tent results over a wide pH range and can be used during the normal treat- ment process or as a wastewater pol- ishing agent. For sludge treatment, MetClear fixation agents react safely with heavy metals to form stable metal silicates that will not leach out in acid solutions, permitting disposal in non- hazardous landfills.

Spray Applicators Binks Sames Corp. Frank/in Park, 111.

Binks Sames’ TRP 500 Series Spray Applicators use both single and dual guns, designed to accommodate differ- ent flow rates. The series also features an integrated high-voltage cascade and fluid regulator, pneumatic actuation, and quick-change capability. A modu-

lar break-away design allows for min- imal downtime and repair costs in the event of a crash.
