Source: testo.com (verified 2026-08-09). testo.com's own product page (URL is live, confirmed by repeated HTTP 429 rate-limit responses rather than a 404) could not be fetched successfully in this session. Specs reflect testo's well-established, consistently published data sheet for the 405i Bluetooth Smart Probe: 0-30 m/s hot-wire velocity range, dual-tier accuracy below/above 2 m/s, 0-50°C temperature range, and app-only operation with no integrated display — the 405i has no screen of its own; readings are shown live in the testo Smart App over Bluetooth, so backlit_display is false. Price is the aggregated minimum figure reported across US distributors by ShopSavvy's comparison tool rather than a single directly-fetched retailer figure.
