High precision chilled mirror hygrometers improve the quality of emissions testing

Emissions testing is an important environmental requirement in the design and production of internal combustion engines.

The evaluation of engine emissions during engine design under indoor-related conditions and over defined timescales requires the use of climate-controlled emission testing systems such as emission test chambers and cells.

During an emission test, the control of the stability of ambient conditions plays an important role for the outcome of the test. Among other values such as temperature or pressure, the relative humidity has to be measured to comply with the defined test standards such as the EPA standards.

The Michell high precision range of cooled mirror hygrometers are the most precise instruments currently available on the market to help to meet requirements for relative humidity measurement from any of the leading environmental control authorities. With accuracies of 0.1°C dp, and based on the fundamental measurement principle which has no inherent drift, the new chilled mirror hygrometer S8000 Remote, combines flexibility with outstanding accuracy exceeding the requirements dictated in the emissions control legislation.

The customer can use the instrument as a reference for other RH sensors used to control the relative humidity of the engine test cell or use it as a primary measurement and control device in the emission testing system.

With almost 40 years of experience in cooled mirror technology built into every single Michell Instruments hygrometer the company has been helping numerous car and combustion engine manufacturers to push the boundaries and exceed the requirements of the environmental legislation.

Every instrument is delivered fully calibrated, traceable to National Standards - we maintain direct traceability to NPL (London, UK) and NIST (Washington DC, USA) through our UKAS accredited Humidity Calibration Laboratory. This satisfies the most stringent of quality system requirements and gives ultimate confidence in the measurement being made.
