## Overview

The testo 405i Bluetooth Thermal Anemometer Smart Probe is a cutting-edge tool designed for professionals needing precise measurements of volume flow, air velocity, and temperature. Featuring a telescopic probe extending up to 400 mm and seamless integration with the testo Smart Probes App, it offers customizable duct configurations and real-time data logging. Lightweight and compact, it’s engineered for efficient use in ventilation systems, backed by Testo’s 60+ years of innovation in measurement technology.

## Description

From the manufacturer 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 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.

Review: Five Stars - Perfect product for the application
Review: 450i anemometer: works fine - The 450i anemometer worked fine (screenshot attached). I did the math using the cross-section area of the duct, and the number was within 5% of than the rated output of the blower that I was to create the air flow. The app was easy to install, but asked access to my contacts and location. The manufacturer should offer options to disable this, and should not bundle reviews for all smart probes into one. Please offer the case with foam inserts to keep the probes. Thanks!

## Features

- For measuring volume flow, air velocity and temperature
- Simple configuration of the dimension and geometry of the duct cross-section for determining the volume flow

## Questions & Answers

**Q: Can you use it to measure air mass? Like kg / hour? And does it compensate for air temperature and air pressure?**
A: It measures air velocity, period. Does not compensate for pressure or temperature. Does not measure air mass flow directly.

**Q: Can it calculate or convert to Feet per minute?**
A: Here are the specs you are looking for:

Measuring range: 0 to 6,000 fpm
Accuracy: ±(20 fpm +5 % of m.v.) (0 to 394 fpm) / ±(59 fpm +5 % of m.v.) (394 to +3,000 fpm)
Resolution: 1.97 fpm
Volume flow: (cfm) 0 to 99,999 cfm (Resolution: 0.1 cfm)

**Q: Can you use it to measure the delta?**
A: There's a trendline function that can keep track of changing temp over time.

**Q: Does this device show a live CFM reading?**
A: Why yes it does sir

### ⭐ UTTER RUBBISH!!!
*by R***G on 20 July 2017*

UTTER RUBBISH! THE BLUETOOTH CONNECTION LASTED FOR JUST A FEW MINUTES AND THEN DISCONNECTED ITSELF AND IT WON'T RECONNECT. THE INSTRUCTION MANUAL IS TOTALLY USELESS AND I HAVE ABSOLUTELY NO IDEA HOW TO TRANSMIT DATA FROM THE PROBE TO MY PHONE. IT IS GOING STRAIGHT BACK TO WHERE IT CAME FROM!
