TOC is widely accepted as a measure of the organic contaminant in water. The 1950plus is designed for a range of industrial applications and offers many modern features for
easy operation and maintenance. The1950plus-turbo
is designed for pure water applications such as USP grade water in pharmaceutical manufacturing and ultrapure water in semi-conductor manufacturing facilities.
are also made in Loveland, Colorado and are an upgrade of the world renowned BTG product line. A strong feature of these products is that they are all self cleaning. Included are dual channel (i.e. two sensor) transmitters for a mix and match of suspended solids or turbidity sensors in either submersible or insertion styles. Other products include a
for slurry and sludge measurements, and a for sludge blanket control.
are manufactured in France. They have been designed to common international connection and fittings specifications and as such, are easilly applied in North America. The Polymetron water
analyzer division of Zellweger was established in Switzerland in 1946 and was moved near Paris in 1990. They have steadilly upgraded and modernized their products, incorporating leading edge technology, and earning themselves a
world-wide reputation for know-how in on-line water instrumentation. Their analyzer product line is very extensive and includes: (single and dual channel), specialized for traditional, auto-cleaning and ultrapure water applications, (single and dual channel), of 2 electrode and torroidal design for sanitary or regular applications, and analyzers for ,

are in the group of the 5 top
manufacturers in the world. They have lead the way over the last 25 years in establishing patented technology that has been adopted by transmitter manufacturers and customers alike. They produce probes for industrial, steam sterilizable and laboratory applications. They provide, arguably, the best quality probes for the price of any supplier. PML Process maintains this advantage by selling ISI probes at the standard U.S. list price in Canada. PML stocks probes in Mississauga for rapid delivery.
