1. What does DD28 3 (6) A and 1950 R/KWH mean for an old-fashioned single-phase electricity meter?
The calibration current is 3A, and the maximum current is 6A. R means rotation. 1950 converted to 1 degree. Attached is the manufacturers website, you can take a look and contact them to inquire.
2. Brookfield Viscometer Company Introduction
Brookfield Engineering Laboratory, a global leader in the manufacturing of laboratory and in-line production viscosity meters and rheometers, has solidified its position as the go-to provider for these instruments. Industry professionals, suppliers, and clients often rely on Brookfield"s viscosity meters, with various standards and industrial norms referencing their use. Their product range spans from dial (analog control) to digital display models, including programmable options for in-line production processes, such as probe, container-based, online, and flow-through devices.Brookfield"s versatile technology is widely utilized across sectors like food, printing inks, paints and coatings, solvents, adhesives, petroleum products, plastics, health and beauty products, and in industrial product development and manufacturing. The company has a rich history, dating back to 1932 when Don Brookfield"s pioneering work led to the creation of a viscosity meter for testing liquid properties in synthetic resin production.In 1993, Brookfield earned ISO9002 certification for quality and precision, which was later upgraded to ISO9001 in 1997. The company"s growth took a significant leap in 1999 when it relocated to Middleboro, Massachusetts, after 48 years in Stoughton. Brookfield now operates a sprawling 93,000 square feet facility, with subsidiaries in the UK and Germany, providing sales and technical support services in those regions. A robust network of agents worldwide ensures its products and services are accessible globally.Operating with a family-oriented approach, Brookfield transitioned from private ownership to an employee stock ownership plan in 1986. The Brookfield family retains significant control, reflecting their commitment to their employees" welfare. Through the employee stock program, initiated by Don Brookfield, the company empowers its staff to become shareholders and provides additional retirement benefits.When faced with viscosity challenges, Brookfield"s reputation as a trusted partner and reliable friend is widely recognized. Its viscosity meters are the preferred choice for quality control, research and development, and manufacturing processes, establishing its dominance in the industry for over 65 years.Beyond just scientific excellence, Brookfield"s success lies in its widespread adoption in global industrial sectors. Their The principle of viscosity measurement, using the torque generated by a rotating rotor in the tested fluid, has become a standard in viscosity measurement worldwide, surpassing competitors in recognition. Brookfield is a leading laboratory and online rotational viscometer manufacturer in the world today. Most quality control, research and development, and production process departments consider Brookfield viscometers as their primary choice for viscosity measurement. The excellent reputation of the Brinell viscometer is not only based on an outstanding scientific principle. More and more Brinell viscometers are being applied in industrial fields worldwide, far exceeding other viscometers. All Brinell viscometers use the well-known princip
