Liquid Density Analyzer

The DM8 liquid density analyzer measures liquid density of general process liquids with high sensitivity and excellent stability. It has a measuring density range of 0 to 2.0 g/cm3, and unaffected by flow rate and viscosity. Besides general-purpose sensor, sanitary and explosionproof sensor are also available.

Advanced Reflux Sampler

The Yokogawa Advanced Reflux Sampler is designed to provide conditioning for severe service analysis needs using a simple self contained two stage system. The first stage is designed to provide filtration of particulate and passive cooling.


Infared and Fourier Transform Near-Infared Analyzers consists of our IR200, IR400 and NR800 series analyzers.

NIST Buffers, ORP (mV) & Conductivity Solutions

MSDS are data sheets listing general chemical compositions and certain characteristics of chemicals. The purpose of these datasheets is to provide information for safe handling and measures to be taken in case of accidents or spills. These MSDS forms are included with the specific products. Translations in other languages will be available from this web page.

Analyzer System Integration

Measurementation is an engineering, consulting, and fabrication company specializing in all aspects of analyzer system integration since 1967. They became fully integrated with Yokogawa Corporation of America in 2002.
