TSI ALNOR EBT731 Air Flow Capture Hood Digital 2 x 2 Hood

TSI Alnor EBT731 Balometer air flow capture hood (equipped with a digital micromanometer) takes air volume readings directly from diffusers and grilles with high efficiency. This multipurpose electronic air balancing instrument is useful for test & balance contractors, commissioning agents, facility managers, ventilation system installers and health & safety specialists in HVAC applications to control airflow.

Working Mechanism:

• Place the TSI Alnor EBT731 air flow capture hood over the duct or any other enclosed area where the airflow is to be measured.
• Connect the unit to the hood using appropriate fittings and hoses.
• Turn on the unit and allow it to take readings to determine the airflow rate.

Features:

Capture Hood

• TSI Alnor EBT731 Balometer air flow capture hood's ergonomic design and light weight allow easy, single-person operation.
• It provides back pressure compensation for accurate readings at high flow rates.
• This hood automatically senses and displays supply or return flows.

Detachable Micromanometer

• This micromanometer accurately measures pressure, velocity and flow.
• It has an auto-zeroing pressure sensor to reduce user steps and save time.
• Its automatic density correction increases reading accuracy.
• The intuitive menu structure allows easy setup and use.
• It has a large graphic display with a backlight to showcase up to five measurements.
• This micromanometer has an integrated Log-Tchebycheff duct traverse application to simplify calculations.

Compatible Accessories:

• TSI Alnor Air Flow Probe: This probe performs duct traverse and measures face velocity. It is also ideal for small-diameter ductwork.
• TSI Alnor Air Velocity Probe: This thermoanemometer probe can be equipped to measure air velocity and temperature simultaneously.
• TSI Alnor Velocity Matrix Probe: This 16-point telescopic velocity matrix is perfect for applications that require large surface area measurements.
• TSI Alnor CH-STAND Capture Hood Stand: This stand extends up to 15 feet, allowing users to take readings from ceiling diffusers without using ladders.

Standards and Approvals:

• NIST

Frequently Asked Questions:

Q. How to clean this TSI Alnor EBT731 unit?

A. Use a soft cloth damped with mild detergent to clean the fabric hood, micromanometer and case.

Q. How to assemble the capture hood?

A. The capture hood comes partially assembled with the 2 x 2 ft nylon hood attached to the base. To complete the assembly, follow these steps:

• Place the capture hood's base on the floor.
• Lift the top of the fabric and insert one end of a support pole into its pole mount in the base.
• Grip the support pole and bend it slightly to insert the top end into the support pole cup (set in the fabric frame's opposite corner).
• Insert the rest of the poles in the same way.

Q. Does this unit require calibration?

A. This TSI Alnor unit must be calibrated annually to avoid errors and maintain accuracy.

Q. How to retract the probe?

A.

• To retract the probe, hold the handle in one hand and pull the probe cable gently with the other until the smallest antenna section retracts.
• Never retract the probe by pushing the tip.
