## Description

Testo 405i is a heat-ray wind speed smart probe that can measure wind speed, wind temperature and air flow. Small and portable, the measurements can be viewed on your smartphone or tablet via Bluetooth. You can also easily get professional analysis results with the calculations and display functions using the dedicated app. Accuracy range: 0-15m/s

Review: 使用にあたっては専用アプリをインストールしたスマホ(またはタブレット)が必須です。本体には測定結果の表示部はありません。私は経時ログを取る必要があったのでそれでもよいのですが、単に風速を測定したいだけの方には本体＋スマホの２台持ちになるので少し面倒かもしれません。 なお、そのアプリですが、「testo Smart」でないと動きません。製品の梱包箱に「Download testo Smart Probes APP」と書かれた小さな紙が入っていたのですが、その「testo Smart Probes」は別のアプリ(旧製品用？)でありこの製品とは接続できません。紛らわしいのでご注意ください。この紙がなぜ入れてあるのか不可解です。 アプリ自体の機能は必要十分と思われます。desertcartの説明文に書かれていること以外に下記のことができます。 ・風速の単位：m/s, mph, km/h, fpm ・測定間隔：1sから23h59m59sまで1s刻みで任意 ・タイマー測定可能 ・気圧補正機能あり ・ログはcsvあるいはjsonでエクスポート可能 とても小型で、折りたためばポケットにも入ります。しいて言えば三脚等に固定するためのネジ穴がないことだけ残念ですが、大きさとの兼ね合いでこうなったのかもしれません。 ともあれ、ログ取り可能な熱線式風速計がこれだけ手軽に手に入るのは本当に嬉しいです。

*by ヨ***ト on August 17, 2025*

満足度が高い機器。 良い点∶軽量、小型、スマホで任意にデータを記録(ロガー)出来る。 悪い点:運搬ケースを別で準備。フィールドで使用する場合、本機とスマホと記録紙を広げる為、機器の固定(座り)が今ひとつ。本体とスマホを一纏めで設置出来る様に治具作成する予定。
