TSI Alnor EBT731 Balometer Capture Hood

The TSI Alnor EBT731 Balometer Capture Hood is a true multifunction ventilation testing instrument, capable of measuring air volume at diffusers and grills, balancing air flow systems, and troubleshooting HVAC installations. The EBT731 features a detachable manometer that can be used to measure air velocity in ductwork with the included pitot probe, or to check static pressure using the included static pressure probes. The EBT730 manometer can also be used to measure building pressurization, depressurization, and zone pressure differences. Another significant advantage of the EBT730 manometer is its ability to connect to optional probes including the thermoanemometer probe, the temperature and humidity probe, the straight air flow probe (straight pitot), and the Velocity Matrix for taking velocity measurements at large filters or exhaust hoods. Various hood sizes are available for many different applications including Biological Safety Cabinet Hood kits, which are used to certify Class II bio-safety cabinets by taking direct in-flow measurements for NSF compliance.

The EBT731 Balometer is being used by HVAC contractors, energy auditors, commissioning agents, and facility managers to save time and labor cost by automatically calculating CFM from return or supply registers. The flow hood is ideally suited to quickly balancing an air flow system, or for confirming proper operation of ventilation fans. The TSI Alnor EBT731 sets up quickly, and is lightweight enough (just 7.4 pounds) for one person operation.

The EBT731 Balometer Capture Hood incorporates the latest in TSI Alnor software technology. The included LogDat-CH software can be used to transfer capture hood and manometer data to a PC via the included USB cable for reporting and analysis. The manometer can also connect wirelessly using Bluetooth to the LogDat Mobile app for Android platforms. LogDat Mobile can remotely view and capture balometer and manometer data, and can even record pictures, voice notes, statistics and graphs. LogDat Mobile can export results to an SD card, Gmail, or your Google Drive. Also available for the EBT731 Capture Hood is an optional hood stand that can extend the instrument up to ceilings as high as 15 feet, eliminating the trouble of constantly moving the ladder around.
