Part No. AP1-24 | 24-Inch Coiled Cable
Product Overview
The Dwyer AP1-24 is a thermo-anemometer air velocity and temperature probe featuring a 24-inch coiled cable and 8-inch (203 mm) insertion depth. It measures air velocity from 45 to 6000 FPM (0.23-30 m/s) with ±3% of full-scale accuracy across 4-32°C (40-90°F).
The probe also measures air temperature from -40 to 100°C (-40 to 212°F), with ±0.5°F (±0.28°C) accuracy. With a response time of approximately 1 second, it is suited to efficient duct traverses and repeated airflow measurements.
The 24-inch coiled cable provides a practical balance between working reach and cable management. The 8-inch insertion depth allows the probe to reach into standard ductwork through suitable test ports. Weighing 362 g (12.8 oz), the AP1-24 is designed for routine HVAC testing, air balancing, duct traverses and AHU commissioning.
The AP1-24 is part of the Dwyer AP1 probe range and is intended for use with compatible Dwyer thermo-anemometers. For applications requiring more reach, the AP1-36 provides a 36-inch coiled cable, while the AP1-18 uses a shorter 18-inch cable.
Key Benefits

Who This Product Is Best For
- HVAC technicians performing duct traverses in plant rooms, risers and air handling areas.
- Air balancing engineers who prefer a manageable mid-length probe cable.
- AHU commissioning teams checking airflow at duct test ports.
- Contractors and service teams replacing a compatible Dwyer thermo-anemometer probe.
- Users building a standard HVAC test kit around a compatible Dwyer thermo-anemometer.
How to Use / How It Works
- Connect the AP1-24 probe to a compatible Dwyer thermo-anemometer.
- Use the probe markings to set the required insertion depth.
- Insert the probe through the appropriate duct test port with the sensing tip positioned correctly in the airflow.
- Allow approximately 1 second for the reading to respond, then record the air velocity and temperature.
- Repeat measurements at the required traverse points to evaluate airflow distribution.
Frequently Asked Questions
What cable length does the Dwyer AP1-24 have?
The AP1-24 has a 24-inch coiled cable, providing a practical balance between reach and cable management.
What air velocity range does the AP1-24 measure?
It measures 45-6000 FPM (0.23-30 m/s) with ±3% full-scale accuracy across the specified 4-32°C (40-90°F) range.
What temperature range does the AP1-24 cover?
The probe measures air temperature from -40 to 100°C (-40 to 212°F) with ±0.5°F (±0.28°C) accuracy.
How quickly does the AP1-24 respond?
The specified response time is approximately 1 second, making it suitable for repeated airflow measurements and duct traverses.
Is the AP1-24 suitable for duct airflow measurement?
Yes. Its 8-inch (203 mm) insertion depth, 24-inch coiled cable and airflow measurement range make it suitable for duct testing, HVAC balancing and commissioning applications when used with a compatible meter.
How does the AP1-24 compare with the AP1-18 and AP1-36?
The AP1-24 uses a 24-inch cable. The AP1-18 provides a shorter cable, while the AP1-36 provides a longer 36-inch cable. Select the cable length according to the working distance and access conditions of your application.
