TESTO 6744 DEW POINT TRANSMITTER W/ DISPLAY

Dew point is the temperature at which moisture present in air condensed to form water droplets. Moisture in the industries is undesirable as it can cause damage to process, product and instruments which can cause huge loss to the industries. Air, compressed air and gases are used in all areas of industry. Humidity is normally undesirable because it can cause mechanical damage, corrosion or adhesion of the material, which can increase the operating costs or even impair the quality of the end product. The international standard ISO 8573 defines seven classes of compressed air quality based on moisture content, oil content and particle content. The main way of reaching and ensuring compliance with a quality class involves installing a suitable dryer. Pressure dew point transmitters/ switches are used to monitor the dryer and its results. We provide a wide range of solution for dew point measurement like Testo 6741 which is a dew point switch, 6743 and 6744 which are dew point transmitters. Then we have 6781 that can be used for monitoring and controlling. Features: Specially developed for measuring trace humidity in compressed air or dry air ( granulate dryer) Testo humidity sensor with tried and tested long-term stability Measuring range of -45 ° Ctpd to + 30 ° Ctpd Choice of G ½ “ or NPT ½ “ process connection User-friendly operation via the display menu Without display via the internal interface On-site 1-point adjustment Analog output: 4 to 20 mA ( 2-wire) and optional alarm plug with 2 integrated switch outputs Compact design with 350° rotation of the housing for optimum positioning of the display Adjustment of trace humidity can be performed on-site without reference measuring instrument with accessory part ( 2-pressure adjustment device) -> replaces costly adjustment with dew point mirror.
