Supported Applications
The Omega HHC261 is a vane-type hygro-anemometer designed to measure wind velocity, relative humidity, and air temperature. It features a digital display for air speed (upper) and temperature (lower), with a vane for airflow sensing.
Operating Conditions & Performance
The HHC261 operates within an ambient environment of 0°C to 50°C (32°F to 122°F). The device is powered by two 1.5V AAA size batteries, with a typical battery life of 50 hours using alkaline cells.
Performance specifications for the HHC261 include:
- Wind Velocity Range: 0.4 to 20 m/s, 80 to 4000 ft/min
- Relative Humidity Range: 0% to 100% RH
- Air Temperature Range: -20°C to 60°C (-4°F to 140°F)
- Wind Velocity Accuracy: ±0.2m/s + 2% of reading, ±40ft/m + 2% of reading
- Relative Humidity Accuracy: ±2.5% at 25°C (77°F), 10% to 90% RH; ±5% at 25°C (77°F), 0% to 10% RH, 90% to 100% RH
- Air Temperature Accuracy: ±0.5°C for 0°C to 45°C, ±1.0°C for -20°C to 0°C and 45°C to 60°C; ±1.0°F for 32°F to 113°F, ±2.0°F for -4°F to 32°F and 113°F to 140°F
- Resolution: 0.1m/s or 1ft/m (Wind Velocity); 0.1°C or 0.1°F (Air Temperature)
- Sensor Response Time: 60sec typical for Relative Humidity (90% of Total Range)
The device includes a low battery indication when voltage drops below the operating level and features MAX/MIN recording, averaging, and backlighting.
Configuration Options
The HHC261 series is offered as a handheld unit with specific dimensional constraints suitable for field use. The overall dimensions are 24.7mm(T) x 50.9mm(W) x 132.9mm(H), and the weight is approximately 119g including batteries.
Key configurable or included features include:
- Sensor Type: Digital Capacitive humidity sensor
- Housing Protection: Slip-off hard cover shell (included)
- Accessories: Carrying strap and protection cap are provided with the unit.
- Certifications: CE, UKCA
The device supports multiple units of measurement for wind velocity and temperature. Storage conditions require temperatures between -20°C to 60°C (-4°F to 140°F) with humidity up to 80% R.H., provided the battery is removed from the meter.
Key Product Differences
The HHC261 is part of a broader family of rugged handheld environmental meters that includes models for temperature, pressure, RPM/light, and air flow/humidity/dew point/wet bulb measurements. While other series members (HHC201, HHC210, HHC280, HHC281, HHC230, HHC250) offer different measurement types such as Type K Thermocouple temperature or differential pressure, the HHC261 is specifically configured for wind velocity and humidity applications.
All models in this family feature a 1-year warranty. The HHC261 distinguishes itself within the lineup by combining vane-type airflow sensing with digital capacitive humidity measurement in a single handheld unit.

Not quite as advertised
The ad claims the meter measures "dew points". It doesn't. It measures wet bulb and dry bulb readings and you can train your people to read a psychometric chart (I hope you have better luck than I with that). Otherwise, like most Omea products it's a good value and fairly well made.
