Edgetech Instruments Introduces the AcuDew Aluminum Oxide Moisture Transmitter

The Edgetech Instruments AcuDew Moisture Transmitter is a two wire, loop powered moisture transmitter with linear 4 to 20 mA output corresponding to the measured moisture content. Its high capacitance aluminum oxide sensing element provides outstanding sensitivity, especially at low moisture content, as well as high speed of response and repeatability. The advanced electronic design of the AcuDew uses modern, high speed, high resolution hardware and software techniques for superior performance.

The AcuDew can be factory configured to provide an output corresponding to various moisture parameters including dew/frost point temperature, parts per million by volume or parts per billion by volume. Locally and remotely mounted display and power supply devices are optionally available. The Field Span Verification (FSV) feature of the AcuDew allows the user to ensure accuracy of the transmitter between annual factory recalibrations.

Bob Kenney, Edgetech Instruments’ VP of Sales and Marketing, Aluminum Oxide Division said: “The aluminum oxide moisture sensor is used in greater numbers globally than any other industrial moisture measurement technique. High sensitivity, compact design, high pressure capability, ease of use and versatility make the aluminum oxide moisture transmitter the recognized best choice for continuous moisture measurement in many applications including process gases, high purity gases, glove box environments, compressed air and injection molding. The AcuDew is a high-performance moisture transmitter that represents a true advancement in aluminum oxide moisture sensing.”

Each AcuDew Moisture Transmitter is delivered with an ISO/IEC 17025 certificate of calibration, traceable to NIST. The AcuDew is calibrated and supported in the USA, in a modern ISO/IEC 17025:2005 accredited calibration laboratory located in an ISO 9001:2015 registered facility.
