Dewpoint transmitter to -90 °Ctd - testo 6781 - 1

The transmitter testo 6781 was developed specially for trace humidity measurement in compressed air international norm ISO 8573 categorizes seven |k classes of compressed air. High-performance / fclO/y-e"! ^ adsorption dryers are required in order to meet the highest quality classes 1 and 2. They can be monitored by the testo 6781 down to very low The newly developed sensor with sol-gel technology fast response time, thus guaranteeing highest process security. Measurement of dewpoints in the measuring New, very condensation-proof sensor with sol-gel technology guarantees highest process security Automatic self-adjustment ensures high accuracy Optional display with multi-language user menu Self-monitoring of the transmitter guarantees high system availability adjustment and analysis saves time and costs in • Dewpoint measurement in compressed air in ISO Classes 1 (<-70 °Ctd) and 2 (<-40 °Ctd) Monitoring of adsorption dryers, granulate dryers Quality assurance for noble gas preparation

Technical data The determination of measurement uncertainty takes place according to GUM (Guide to the Expression of Uncertainty in Measurement): For the determination of measurement uncertainty, the accuracy of the measuring Instrument (hysteresis, linearity, reproduceablllty), the uncertainty contribution of the test site as well as the uncertainty of the adjustment site /works calibration are taken Into account. For this purpose, the value of k=2 of the extension factor, which Is usual In measurement technology Is used as a basis, which corresponds to a trust level of 95%. This total...
