Probe Type Gas Analyzer TDLS8100
Yokogawa’s new TDLS8100 continues to house all of the industry’s leading features from the TDLS8000, but now only requiring a single-flange installation. An in-situ measurement with a probe removes the requirement for sample extraction and conditioning and can be used in a variety of aggressive process conditions.
Built upon Yokogawa’s second generation of TDLS analyzers, the platform still retains its improved reliability, ease of installation, and reduced maintenance requirements, but now does so with a lower total installed cost for O2, CO/CH4 , and NH3 measurements.

Industrial Combustion sources such as thermal cracking furnaces and, process heaters play a critical role in the process industry.
En el mantenimiento y la administración de plantas industriales, monitoreo del pH de las aguas residuales / ORP es a la vez una obligación legal y una necesidad necesaria para la protección del medio ambiente. El Monitoreo sin estar atento puede llevar a consecuencias graves.
Package boilers require less fuel and electric power to operate and are widely used in the pharmaceutical, food, ceramic, and other industries. A package boiler operates more efficiently if the oxygen concentration in the flue gas is reduced.
Storage tanks are used in a variety of industries ranging from holding crude oil to holding feedstock for vinyl chloride monomer (VCM).
