HHF1001A Wireless Handheld Air Temperature & Velocity Meter

Supported Applications

The Omega HHF1000 Series is a handheld air velocity and temperature meter designed for research & development labs, HVAC applications, and manufacturing processes. The series measures air velocity, mass flow, volume air flow, and air temperature in clean air flows within ducts and pipes.

Operating Conditions & Performance

The HHF1000 Series utilizes a sensor design based on three RTD elements: one 100 Ω element for temperature measurement and two 1000 Ω elements that measure velocity via heat loss. The series operates within an air velocity range of 0 to 5000 FPM (0 to 25 m/sec) and a process temperature range of -40 to 93°C (-40 to 199°F). Accuracy is specified as 1.5% full scale for air velocity and 0.5% full scale for air temperature.

Operating ambient conditions are defined by component location: the sensor probe operates from -40 to 93°C (-40 to 199°F), while the electronic case operates from 0 to 50°C (32 to 122°F). The unit is powered by a 9V Lithium battery or a 9 Vdc adaptor, with a continuous operation battery life of 40 hours. Media compatibility is restricted to clean air and Nitrogen; the series is not explosion proof nor intrinsically safe.

Configuration Options

The HHF1000 Series offers configurable probe configurations and communication interfaces tailored for specific measurement environments:

• Probe Configurations: Available with a fixed 305 mm (12") stainless steel probe or a remote telescopic probe adjustable from 305 to 914 mm L (12 to 36"). The standard probe diameter is 6 mm (¼" OD).
• Display & Output: Features a backlit LCD display showing air velocity in FPM, m/sec, MPH, and Km/hour, and temperature in °F and °C. Volume flow readout includes CFM and CMM.
• Data Communication: Models include options for a USB PC serial interface with Windows® based data logging software or a Wireless RF transmitter operating on the ISM 2.4 GHz band (direct sequence spread spectrum).
• Wireless Performance: The wireless option provides an indoor/urban range up to 40 m (130') and outdoor line-of-sight range up to 120 m (400'). A UWTC-REC1 48-channel wireless receiver is required for the PC interface.
• Additional Features: Includes high/low alarm indications, adjustable display response time, atmospheric pressure compensation, and optional NIST traceable 4-point calibration certificate (-CAL-3).

Key Product Differences

The series is differentiated by probe type and wireless capability across four primary models:

• HHF1001A: Air velocity/temperature meter with a fixed 305 mm (12") stainless steel probe.
• HHF1001R: Air velocity/temperature meter equipped with a remote telescopic probe adjustable from 12 to 36 inches.
• HHF1001A-W: Includes the fixed probe configuration and wireless PC communication option (ISM 2.4 GHz).
• HHF1001R-W: Combines the remote telescopic probe with the wireless PC communication option.
