Description

The Fluke 925 ESP is a precision vane anemometer engineered for field service technicians and HVAC professionals. It utilizes a mechanical vane sensor for direct wind speed measurement and a thermistor for ambient air temperature, providing comprehensive airflow analysis. The unit’s robust over-mold construction ensures durability against accidental drops and impacts in demanding work environments.

Its extended 1-meter cable between the sensor head and display allows the probe to be positioned deep into ducts or vents while the operator maintains a clear view of the dual LCD screen. The instrument supports data capture, averaging, and alarm functions to streamline diagnostic workflows, making it ideal for system balancing, ventilation checks, and environmental monitoring.

Key Features

  • Dual-measurement vane anemometer for wind speed (m/s, ft/min) and air temperature (°C/°F).
  • Calculates derived airflow volume in CFM (Cubic Sensor feet per minute) and CMS (Cubic Sensor meters per second).
  • Rugged over-mold housing designed for shock resistance and extended field use.
  • 1-meter flexible extension cable separates sensor from display for probing confined spaces.
  • Comprehensive data functions: Reading Hold, Min/Max recording, and user-selectable averaging (1-8 samples).
  • Configurable min/max alarms with visual/audible alerts for out-of-spec conditions.
  • Auto power-off conserves battery life after 20 minutes of inactivity (can be disabled).
  • Long-life 9V alkaline battery operation supports up to 100 hours of continuous use.

Applications

  • HVAC system performance testing, balancing, and duct airflow measurement.
  • Industrial health & safety ventilation checks and fume hood certification.
  • Environmental and meteorological wind speed monitoring for field studies.
  • Building management system (BMS) commissioning and indoor air quality (IAQ) assessments.
  • Cleanroom and laboratory airflow velocity and temperature profiling.

Frequently Asked Questions

What is the measurement range and accuracy of the Fluke 925 ESP wind speed sensor?

The Fluke 925 ESP measures wind speed from 0.40 to 25.00 meters per second (80 to 4900 feet per minute). Accuracy is typical for a mechanical vane anemometer, suitable for professional HVAC and industrial applications. It also calculates derived airflow volume in CFM and CMS based on the measured velocity.

Can this anemometer measure air temperature as well?

Yes, it features an integrated thermistor sensor that measures wind temperature from 0°C to 50°C (32°F to 122°F) with a resolution of 0.1 degrees. The temperature is displayed alongside wind speed on the dual LCD screen, providing a complete airflow profile.

How does the 1-meter extension cable benefit measurements?

The 1-meter flexible cable separates the vane sensor from the display unit. This allows you to insert the probe deep into ductwork, vents, or other confined spaces while keeping the display in a visible, accessible location for easy reading and data capture.

What data logging and analysis functions does it include?

The unit includes Hold, Min/Max recording, and an averaging function for 1 to 8 consecutive readings. You can set audible/visual alarms for minimum and maximum limits. It can store a single data point for up to 2 hours, facilitating extended monitoring sessions.

What type of battery does it use and what is the expected lifespan?

It is powered by a standard 9V alkaline battery (included). Under typical use, the battery provides up to 100 hours of continuous operation. An auto power-off feature activates after 20 minutes of inactivity to conserve battery life, but this can be disabled if needed.
