- Nalfleet, Bull And Roberts Introduces New Approach To Water Treatment Maritime Reporter, Nov 1988 #52
New simplified and accurate chemical test procedures are now available from Nalfleet, Bull and Roberts, Springfield, N.J., with the Orbeco-Hellige photometric analyzer.
This new portable unit covers 90 different tests (many using ASTM and EPA methods), for quick and accurate testing even by untrained personnel. The analyzer is precalibrated for all photometric tests; therefore, no standardization is required.
Many tests take less than one minute, even for tests previous- ly requiring samples to be sent to an analytical laboratory ashore.
Nalfleet, Bull and Roberts has also moved into the computer age with the introduction of Nalco's Trendcheck Data Management Program.
Trendcheck serves as an electronic information center that stores, retrieves, evaluates and interprets logged-in water treatment data. According to the company, Trendcheck, when customized aboard a particular vessel, will provide better data management, a timely response to problems via "real time" feedback, and trend analysis via past-data retrieval.
Both data and trend graphs are displayed and can be printed out.
What this means to onboard engineers, the company says, is improved quality and consistency in maintaining their water treatment programs.
Nalfleet, Bull and Roberts continues to improve its expertise and pass it along to its customers. With its long history of water treatment expertise, present products and worldwide service, and movement ahead into computer-based data management, it now offers an individual approach and cost-effective management of shipboard water chemistry.
