Dewpoint transmitter


Vaisala dewpoint transmitter is an ideal choice or industrial applications where there is a need to control dryer performance in low dew points. The DMT340 is remarkably stable in the long term and it has good accuracy. The transmitter's measurement range is wide - it measures dew point temperature from -60 ºC to +60 ºC with an accuracy of ±2 °C. The transmitter has also fast response time. DMT incorporates DRYCAP thin film polymer sensor and auto-calibration software. This a combination makes the transmitter ideal for use in dry ambient. The DRYCAP® sensor is immune to water condensation, particular contamination, oil vapors and most chemicals. Vaisala's unique auto-calibration software corrects the possible dry end error and provides long term stability in dry conditions.
