Part No. AP1-18 | 18-Inch Coiled Cable
Product Overview
The Dwyer AP1-18 is a compact thermo-anemometer air velocity and temperature probe with an 18-inch coiled cable and 8-inch (203 mm) insertion depth. It is designed for use with compatible Dwyer thermo-anemometers and provides a practical solution for airflow measurements where the probe and meter remain relatively close together.
The probe measures air velocity from 45 to 6000 FPM (0.23-30 m/s) with ±3% of full-scale accuracy. It also measures air temperature from -40 to 100°C (-40 to 212°F) with ±0.5°F accuracy. A response time of approximately 1 second helps technicians move efficiently between measurement points during HVAC testing and balancing work.
The 18-inch coiled cable is suited to measurements around AHU access panels, fan coil units and compact duct test locations where a longer lead may be unnecessary. The 8-inch insertion depth provides access to suitable ductwork measurement points, while the 362 g probe remains practical for repeated hand-held measurements.
The AP1-18 is the shortest-cable option in the AP1 range described in the supplied specifications. For applications requiring additional reach, the AP1-24 uses a 24-inch coiled cable, while the AP1-36 provides a 36-inch cable.
With its combination of air velocity and temperature measurement, compact cable length and approximately 1-second response, the AP1-18 is suited to routine HVAC testing, duct traverses, air balancing and commissioning work. The probe is CE approved.
