On-Line Continuous Chemical Analyzers for Liquids, (Hach Company, Innovative Sensors and complimentary products)   products are in use around the world, providing advanced analytical systems and technical support for water quality testing, with solutions for lab, process, and field. Hach is a brand of the Danaher Environmental Water Quality Group, a leading manufacturer of process/environmental controls. Other brands within this group include American Sigma, Bühler-Montec, Contronics and Dr. Lange.

PML Process represents the Hach Polymetron and Astro on-line analyzer product lines.  These include

, ,and . are made in Loveland, Colorado. They comprise the Models and 1950plus-turbo with . 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 , (ppm and ppb levels), , phosphate (low and high levels), , , , , and A variety of parameters are measured with an automatic on-line titratorinluding . New products are being researched and developed continually such as the purewater product called Purecal introduced in the 1st Qtr of 2000. 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.

The PML Process Product groups are divided into chemical Monitoring, Treatment, and Control. Monitoring is further subdivided into Liquids, Gases and Integrated Monitoring Systems. Chemical monitoring naturally goes hand in hand with treatment and control systems.


Monitoring Gases

One of PML's main suppliers of stack emission monitoring analyzers and systems* is CMC Solutions, L.L.C. Another is Optical Scientific who specialize in flow monitoring. Also called Continuous Emission Monitoring Systems or CEMS. On-Line Continuous Chemical Analyzers for Gases.


Monitoring Systems and Services

This is commonly needed to satisfy area classification (i.e. explosion proof areas), weather protection and sample conditioning requirements. In addition to providing products and services, PML Process designs and manufactures analyzer systems for specific applications.



Pretreatment systems include storm water and plate separators, screens, strainers, dissolved air floatation systems and associated chemical injection and flocculation systems. AST's main products are pretreatment systems for industrial and food wastewater and process water systems to create custom designed water for specific applications.



In addition they create factory equipment layouts to automate material traffic and provide general project engineering and project management. They have experise in automating batch blending, adding bulk ingredients with high accuracy, and developing continuous flow processes. TEI has extensive experience in industrial process engineering. They can design new processes and new process equipment.
