Product Detail

Testo’s 440 0.35” Hot Wire Kit is perfect for performing measurements in ventilation ducts. Equipped with the 440 air velocity and IAQ measuring instrument and hot wire probe (Ø 0.35") with temperature sensor, users can measure and document all IAQ-related parameters. A maximum of 3 probes (a Bluetooth® probe, a wired probe and a temperature probe with Type K thermocouple connector) can be simultaneously connected for the most efficient use. Each kit comes supplied with a hot wire probe and case for the ultimate value.
