Measuring convenience thanks to the App

The testo 410i combines professional Testo measuring technology with the efficient functions of an App. Your smartphone or tablet is used as a convenient display for your measuring values on site. You can view all measurement data via the testo Smart Tools App, and email the log immediately as a PDF or Excel file.

Configuration of the volume flow measurement is really easy with the App, partly due to the fact that you can carry out parametrization of the outlet (dimension, geometry) intuitively. Particularly useful: when adjusting a ventilation system, volume flows of multiple outlets can be cross-checked and compared. Timed and multi-point mean calculation also gives you a quick indication of the average air velocity, for example at a ventilation grille.

System requirements:

• iOS 8.3 or later
• Android 4.3 or later
• Bluetooth 4.0

Key Features:

Measures air velocity, volume flow, and temperature
Measures in-duct air flow and automatically calculates volume flow (enter duct dimensions simply)
Small dia. (<0.5”) and 15” telescopic shaft length is ideal for in-duct flow averaging and timed traverse
Perform air duct leakage tests

The VelociCalc® Rotating Vane Anemometer 5725 is a high performance, yet simple – to – use, rotating vane anemometer. High accuracy and reliability make the VelociCalc 5725 the professional’s ideal tool for measuring unevenly distributed or fluctuating flows through heating and cooling coils, diffusers, grilles, and filters. It accurately measures air velocity and temperature, calculates flow rate, performs averaging, and can determine minimum and maximum readings. Using sweep mode you can quickly provide one averaged reading of velocity or volume over a large measurement area. The large vane head automatically averages velocity and volume readings. The VelociCalc 5725 includes variable time constant, sampling and statistics functions and data logging capability.

FEATURES AND BENEFITS
Reversible 4-inch (100 mm) head to read supply and exhaust flows Calculates volumetric flow rate when user inputs duct shape and size, or area Sampling function records multiple point measurements Automatic averaging of air velocity Simultaneously displays velocity and temperature Sweep mode for one overall measurement Optional 36-inch telescopic probe available Compatible with optional Aircone flow hoods Logs 12,700+ samples with a time and date stamp Recall, review, store data
