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.
