Gas Analyzer (5 Gas)

Taylor Dynamometer is proud to offer a cost-effective emissions analyzer for use with the DynPro data acquisition and control system. The system offers superior functionality and an elegantly simple design for a seamless integration with the DynPro system.

Single-beam non-dispersive infrared technology providing unparalleled accuracy and performance in the measurement of HC, CO and CO2 concentrations. NO and O2 are measured using electrochemical sensors.

Taylor Dynamometer is using a dual-head pump, unique one-piece particulate filter and water separator, protected hoses and a sample probe for open exhaust systems. Closed exhaust systems will require fittings (customer supplied) to be inserted into the exhaust stream. Our emissions analyzers are intended to be located near (4 to 6 feet) the source of emissions to eliminate the need for heated sample lines.

Intelligent Warm-Up Mechanism

The Emissions Analyzer provided by Taylor Dynamometer incorporates an “intelligent” warm-up mechanism that allows the analyzer to learn its specific warm-up characteristics. This feature allows the analyzer to self-correct or compensate for its immediate environment as well as temperature changes that may cause measurement drift. The analyzer is ready for use in as little as 20 seconds.
