Product Variants and Model Overview
- Kanomax TABmaster Model 6710: Includes 2 by 2 ft hood frame, detachable meter, 4 tension poles, battery pack, and soft carrying case. Designed for commercial HVAC service and energy auditing.
- Kanomax TABmaster Model 6715: Includes standard 6710 kit plus 5 point NIST traceable calibration certificate. Designed for certified TAB contractors and cleanrooms.

Pro Tip for Commercial Technicians
When measuring low velocity return grilles delivering under 50 CFM, install the Kanomax low flow resistance plug kit inside the base manifold.
This increases velocity pressure across the internal differential grid.
It eliminates low flow measurement fluctuation and ensures repeatable CFM readings on delicate balancing jobs.
Field Analysis and Core Discussion Points
1. What Problem Does This Product Solve?
Measuring volumetric airflow directly at terminal supply diffusers and return grilles is labor intensive.
Traditional methods require holding an anemometer at multiple grid points and manually calculating area multipliers.
These methods are slow, prone to mathematical error, and heavily influenced by room drafts.
Standard capture hoods eliminate the math, but older models are top heavy and difficult to read from ground level.
The Kanomax 6710 TABmaster solves these issues by combining a lightweight frame with an advanced sensor array.
Its color tilting display and automatic temperature and barometric pressure density corrections ensure true CFM delivery calculations.
2. How Well Does It Solve It in the Field?
In hospital corridors and residential utility spaces, the Kanomax 6710 delivers excellent performance.
Touchscreen and Ergonomics: The 3.5 inch TFT LCD uses physical tactile pushbuttons rather than a touch interface.
This design is a major advantage for technicians wearing work gloves.
The color display features sharp contrast, making numbers easy to read in dimly lit plenums.
The screen tilts up to 90 degrees on the base, allowing the technician to view live numbers comfortably from any angle.
Housing Durability and Included Key Parts: The base manifold uses high impact polymer with molded side handles.
The fiberglass tension poles bend smoothly into corner sockets without permanent deformation.
The complete kit packs neatly into a heavy duty padded rolling case that protects the meter during transit.
Real-Time Work and Analytical Capabilities: The meter displays volumetric airflow, face velocity, static pressure, and air temperature simultaneously.
The automatic zero point calibration maintains sensor baseline stability without requiring manual zeroing procedures between registers.
Data Management and Customer Reports: Using the AirNAB mobile app via Bluetooth, technicians can stream live readings to smartphones.
You can assign measurements to specific room numbers and generate pre-formatted CSV or PDF reports before leaving the site.
3. What Does It Do Better or Worse Than Competing Products?
Where the Kanomax 6710 Excels: The full color display is far clearer than monochrome screens found on older legacy hoods.
Unclipping the meter module from the hood frame takes less than 5 seconds.
Connected to a pitot tube, it functions as a full featured micro manometer for duct velocity traverses.
Priced lower than equivalent legacy models, the 6710 offers equal accuracy and superior display graphics at a competitive price.
Where the Kanomax 6710 Falls Short: The lightweight nylon canopy helps keep total weight down to 6.7 lbs.
However, the fabric can snag if pulled forcefully against sharp metal duct edges or suspended ceiling wires.
If the mobile device moves out of Bluetooth range, re-establishing connection occasionally requires restarting the mobile app.
4. Who Should Buy It, and Who Should Not?
Who Should Buy It: Essential for commercial air balancing teams needing fast volumetric readings compliant with NEBB guidelines.
Ideal for HERS raters and energy auditors performing Title 24 compliance and duct leakage diagnostics.
Perfect for facility managers monitoring indoor air quality and ventilation standards.
Who Should Not Buy It: Contractors focused purely on basic residential system replacements rarely need a full commercial capture hood.
A standard vane anemometer combined with static pressure probes offers adequate diagnostic capabilities at lower cost.
5. Is It Worth the Money?
With a retail price point between 2,800 dollars and 3,100 dollars, the Kanomax 6710 represents a serious test equipment investment.
However, its return on investment is easily realized through labor savings.
It reduces testing time per register by 30% compared to manual velocity traverse methods.
Bluetooth app integration enables single operator balancing, eliminating the need for a second technician on the ladder.
Combining a capture hood with a detachable micro manometer eliminates purchasing a separate 800 dollar differential pressure meter.
The Kanomax 6710 pays for itself within three to four major commercial commissioning jobs.

The 6710 automatically detects direction of airflow through its internal pressure manifold grid.
The meter displays a positive reading for supply air and a negative indicator for return air without requiring hose flipping.
2. Can I perform a duct traverse using the detachable meter?
Yes.
Unclip the meter unit from the hood base, connect silicone pressure tubing to the pressure ports, and pair with a pitot tube.
The meter features built-in duct traverse calculation menus for rectangular and round duct shapes.
3. What optional hood canopy sizes are available for the 6710?
Kanomax offers five interchangeable canopy sizes to fit virtually any ceiling grille profile:

- 1 by 4 ft for linear slot diffusers.
- 2 by 4 ft for wide rectangular supply and return grilles.
- 3 by 3 ft for large square ceiling diffusers.
- 1 by 5 ft for long perimeter supply grilles.
4. How does the meter correct for temperature and atmospheric pressure changes?
The 6710 features an integrated absolute barometric pressure sensor and ambient air temperature thermistor inside the manifold base.
The meter automatically calculates actual air density against standard air density and displays true mass flow corrections in real time.
5. What is the recommended calibration interval for the TABmaster 6710?
For certified TAB contractors and HERS raters, factory calibration is recommended every 12 months.
Kanomax provides annual calibration service with multi point verification across low, medium, and high velocity ranges.
