| testo 440 | The testo 440 air velocity and IAQ measuring instrument, combined with high-precision probes (sold separately), enables accurate measurement and data logging of air velocity, indoor air quality (IAQ), humidity, temperature, CO2, and CO levels. It supports up to three simultaneous probes—Bluetooth, wired, and a temperature probe with a type K thermocouple connector—offering automatic probe detection and intuitive measurement menus for effortless operation. Designed for HVAC professionals, it simplifies tasks such as volume flow measurement, turbulence assessment (EN ISO 7730 / ASHRAE 55), and long-term IAQ monitoring. The Bluetooth handle eliminates cable clutter and enables wireless measurements up to 20 meters, while the device's internal memory stores up to 7500 measurement protocols, exportable via USB. The intelligent calibration system ensures high accuracy by requiring only the probes to be sent for recalibration. With a wide range of probes, including options for cleanrooms, fume cupboards, and laminar flow measurements, the testo 440 is a versatile, professional-grade tool for HVAC technicians, facility managers, and air quality specialists. |
| Probe | The vane probe, designed for use with a compatible testo multifunction measuring instrument (sold separately), measures air velocity, volume flow, and temperatures up to +70 °C. It transmits readings via Bluetooth up to 20 m, reducing cable clutter and allowing remote operation with a button on the probe. The intuitive measurement menu enables easy volume flow calculations with multi-point and timed mean calculations. Its universal handle accommodates different probe heads for versatility, and an optional extendable telescope (up to 2 m) facilitates ceiling outlet measurements. The intelligent calibration system ensures accuracy by requiring only the probe head to be sent for calibration. Ideal for air and ceiling outlets, it integrates air velocity values across a large area for precise results and works seamlessly with testovent funnels and volume flow straighteners for enhanced accuracy. The set includes a 100 mm vane probe with Bluetooth, a temperature sensor, a handle adapter, a bracket for testovent funnels, batteries, and a calibration protocol. |
