Viscometers
-
A viscometer, viscosity meter or rheometer is a measuring instrument used to determine a fluid's internal flow resistance or viscosity. The term viscosity typically refers to shear viscosity, i.e., how a material reacts to being sheared. Rotational viscometers with rotating spindles or rotors, also known as "cup and bob" or Searle viscometers, are the most common tools used to measure the shear viscosity of fluids. However, a fluid's viscosity also may be measured on the basis of stretching. The technical term to refer to this is extensional viscosity.A viscometer is frequently used in laboratories, but it also has practical applications in factories and other industrial environments. A viscometer can be an important component in process and quality control. Companies can save money by placing a viscometer in a production line and making fluid viscosity measurements in real time.PCE Instruments offers a variety of handheld, portable, benchtop and in-process, real-time viscometer products that measure the absolute / dynamic (shear) and kinematic viscosity of fluids. Handheld or portable viscosity meter devices allow users to take simple, single-point measurements in the field and in the lab. Benchtop or stationary viscometer devices are complex rheological measuring systems that allow for a more detailed examination of liquid samples.

Trace-Level UV Fluorescence SO2 Analyzer
Model T100U
-
Teledyne Advanced Pollution Instrumentation
The Model T100U Trace-level SO2 analyzer has been developed specifically to address the challenges of low level monitoring as required, for example, in the US NCore network. It uses the proven UV fluorescence principle, and is designed to allow ultra-sensitive SO2 measurements while still meeting the requirements for use as a US EPA compliance analyzer.The analyzer uses both the light and dark phases of the pulsed UV light source to continuously detect and correct for electronic noise, giving exceptionally stable and sensitive performance. A separate UV detector allows the instrument to continuously correct for variations in lamp intensity. Exceptional stability is achieved with the use of an optical shutter to compensate for PMT drift, and a reference detector to correct for changes in UV lamp intensity. A hydrocarbon "kicker" and advanced optical design combine to prevent inaccuracies due to interferents.

Gas Filter Correlation CO Analyzer
Model N300
-
Teledyne Advanced Pollution Instrumentation
The Model N300 is a microprocessor-controlled analyzer based on the Beer-Lambert law that is used to determine the concentration of carbon monoxide (CO) in a sample gas.The N300 uses Gas Filter Correlation (GFC) to overcome the interfering effects of various other gases (such as water vapor) that also absorb Infrared (IR) light. The analyzer passes the IR light beam through a spinning wheel made up of two separate chambers: one containing a high concentration of CO known as the reference, and the other containing a neutral gas known as the measure. The concentration of CO in the sample chamber is computed by taking the ratio of the instantaneous measure and reference values and then compensating the ratio for sample temperature and pressure.
