Dwyer CSG Current Voltage Signal Generator Diagnostic Instrument is great for testing transmitters, transducers, motors, and actuators. The Dwyer CSG continuously ramps an output based on time, minimum, and maximum user-configured parameters.

Dwyer VP1 Vane Thermo-Anemometer Probe Air Velocity Temperature communicates with any of the Dwyer handheld units included with 471B-1, 473B-1, or 485B-1 and allows the user to measure temperature, airflow, air velocity, and humidity. The Dwyer VP1 features an arrow on the vane housing to indicate flow direction and is able to measure velocities down to 50 fpm or 0.25 m/s.

Dwyer RP1 Thermo-Hygrometer Probe RH Temperature Sensing plugs directly into Dwyer Models 471B-1, 473B-1, or 485B-1 and measures temperature, relative humidity, wet bulb, and dew point. The Dwyer RP1 features field replaceable sensors with no additional calibration required and is equipped with a membrane filter to protect the sensor in higher airflow ducts.

Dwyer 475-3-FM Manometer 200-inch WC Intrinsically Safe FM Approved measures negative, positive, and differential pressures of natural gases and air from 0 to 200.0 in w.c. The Dwyer 475-3-FM also measures air velocity when used with a pitot tube.

Dwyer 475-000-FM Manometer 1-inch WC Intrinsically Safe FM Approved measures negative, positive, and differential pressures of natural gases and air from 0 to 1.000 in w.c. The Dwyer 475-000-FM also measures air velocity when used with a pitot tube.

Dwyer WDPM-020 Wireless Manometer Differential Pressure Module 0-20 Inch WC communicates with the Dwyer Model UHH-BTG and allows the user to measure static pressure in ducts, pressure drops across filters, and velocity pressure from pitot tubes or airflow stations. The Dwyer WDPM-020 features a rechargeable lithium ion battery, convenient LED indicator for wireless communication and battery statuses, and the ability to communicate wirelessly at least 50 feet.

Dwyer WDPM-002 Wireless Manometer Differential Pressure Module 0-2 Inch WC communicates with the Dwyer Model UHH-BTG and allows the user to measure static pressure in ducts, pressure drops across filters, and velocity pressure from pitot tubes or airflow stations. The Dwyer WDPM-002 features a rechargeable lithium ion battery, convenient LED indicator for wireless communication and battery statuses, and the ability to communicate wirelessly at least 50 feet.

Dwyer 477AV-1 Digital Manometer Precision Pressure Meter 0-20 Inch WC calculates and measures differential, positive, and negative pressures in addition to volumetric airflow and air velocity calculations.

Dwyer 477AV-0 Digital Manometer Precision Pressure Meter 0-10 Inch WC calculates and measures differential, positive, and negative pressures in addition to volumetric airflow and air velocity calculations.

The Dwyer SAH-22 with its revolutionary Quad Flow design is the most ergonomically, accurate and easy to operate air flow hood on the market.  Dwyer has redesigned the airflow hood to get the most accurate airflow measurements achievable by minimizing back pressure and controlling the flow of air. The Smart Air Hood Balometer along with their PredictAir application software allows air balancing technicians to quickly and efficiently get the job done in half the time.
