F141x FIXINST-Q Dual QCM standard dew point sensor

Measurement Range：-120 … 0 °Ctd

Characteristics

QCM sensor technology is a revolutionary humidity measurement technology. Combined with the newly developed moisture sensitive material, it has excellent signal sensitivity in ultra-low humidity conditions and can measure humidity down to ppb level stably. Patented dual QCM sensors, one for humidity signal and one for pollution signal, automatically compensate for the drift caused by pollution which is common in QCM humidity measurement technology. Innovative temperature compensation algorithm and multi-point temperature-compensated calibration, greatly reduces temperature-dependent dewpoint drift and ensuring high-precision dewpoint measurement over a wide temperature range. Combined with the ultra-high stability of QCM sensor technology, recalibration intervals can be extended to more than two yearsInnovative temperature compensation algorithm and multi-point temperature compensation calibration, greatly improving the sensor’s temperature drift and ensuring high-precision dewpoint measurement over a wide temperature range.
