Supported Applications
The Omega HHF142 Series is a rotating metal vane anemometer kit designed for measuring air velocity and volume flow. The series identity supports applications in HVAC, aerospace development, industrial process airflow, and fluids research. It measures media including air and clean gases.
Operating Conditions & Performance
The HHF142 Series provides measurement ranges dependent on the probe diameter selected. The 25 mm (1") probe model supports a range of 1.5 to 35.00 MPS (300 to 6800 FPM). The 70 mm (2¾") probe model covers 0.25 to 36.60 MPS (50 to 7800 FPM). Accuracy is specified as ±1.0% of reading ±1-digit with a resolution of 1 FPM or 0.01 MPS.
Operating conditions for the instrument are defined from 0 to 50°C (32 to 125°F) ambient temperature, while the probe operates from -20 to 100°C (-4 to 212°F). The series includes a response time of 0.5 seconds per manual documentation and supports humidity up to 95% RH non-condensing.
Key Performance Specifications
- Measurement Type: Air Velocity, Volume Flow (calculated in ft³/min or m³/hr)
- Accuracy: ±1.0% of reading ±1-digit
- Resolution: 1 FPM or 0.01 MPS
- Response Time: 0.5 seconds
- Battery Life: Approximately 150 hours (3 "AA" alkaline batteries)
Configuration Options
The series is configurable across probe sizes, output signals, and environmental protection options. The main unit dimensions are 165 x 83 x 38 mm (6.5 x 3.25 x 1.5"). A hard carrying case is included with the kit.
Probe Sizes
- HHF142A: Handheld anemometer with a 25 mm (1") diameter probe.
- HHF142B: Handheld anemometer with a 70 mm (2¾") diameter probe.
Output Signals & Options
The series supports optional output configurations identified by suffixes in the model number guide. Available outputs include USB communications and 0 to 5 Vdc voltage output. Additional options include a protective boot with splash proof seals (suffix "-PB"). The manual also references analog output capabilities including 4-20 mA, RS-232, and Bluetooth as part of the broader family documentation.
Accessories & Replacement Parts
The kit includes extension rods (flexible, straight, and with handle), a 1.5 m (5') cable, batteries, an NIST calibration certificate, and an operator's manual. Replacement parts are available for the vane probe, connector cables, USB cables, analog output cables, and battery packages.
Key Product Differences
The primary distinction within the HHF142 Series is the probe diameter, which dictates the measurement range lower limit. The 70 mm (2¾") probe allows for measurements starting at 50 FPM compared to 300 FPM for the 1" probe.
Model Number Construction
Variations are denoted by suffixes added to the base model number:
- -PB: Protective boot and splash proof seals.
- -USB: USB communications capability.
- -V: 0 to 5 Vdc voltage output.
The series includes a display described as a 12.7 mm (0.5") LCD with 4-digits and LED backlight, capable of storing up to 10 unique duct sizes for volume flow calculation recall.

HFF142 is a great little tester
Purchased to measure airflow of HEPA filters in a clean-room. Works perfectly and as intended. I would like it to have had a longer cable for a extended reach, but am very pleased with the ease and accuracy of this unit.

The HHF142 Delivers
I have used hot-wire anemometers and swinging-vane anemometers, but this rotating-vane anemometer is by far the best. Quite pleased, and very easy to use.

Can a longer replacement cable be ordered for the HHF142? I would like to get a 10' cable in place of the standard 5' cable if possible
Yes, we can provide a probe with 10 FT cable for the HHF142B-V. Part number is HHF142B-V-10FT. Send us an email to flow@omega.com for price and lead time.

Does the Omega model HHF142 come with calibration certificate?
Thank you for your inquiry! Yes, the HHF142A comes with a NIST calibration certificate

I have HHF142B probe which having reading issue. Reading spike high even no flow and fan no movement. Is it probe problem and should I replace probe only? Please help. For cable, I have check connectivity. There is no intermittent issue.
Thank you for your inquiry and apologize that the anemmeter is an causing issue. Replacing the probe would be the first option and in the event, it continues to behave, please have it returned for evaluation.
