최소 작동 온도 = -20°C Testo 440 Hot Wire Kit in detailKit for carrying out measurements in ventilation ducts: the testo 440 air velocity and IAQ measuring instrument and the hot wire probe (Ø 9 mm) including temperature sensor are all safely stowed away in the case. So you can get down to work straight away! Use this practical kit to measure air velocity velocity, volume flow and air temperature in ventilation ducts. The testo 440 multifunction measuring instrument and the hot wire probe feature an intelligent calibration concept, ease of use and maximum convenience for the adjustment of air-conditioning and ventilation systems.Features and Benefits??Intuitive: clearly structured measurement menu for volume flow and parallel determination of air velocity, volume flow and air temperature in ventilation ducts ??Convenient: integrated telescope that can be extended to 0.85 m, with scaling, makes it easy to carry out measurements ??Reliable: absolute pressure compensation, internal data storage and USB port for data export ??As multifaceted as your challenges themselves: the air velocity and IAQ measuring instrument can be expanded with a large portfolio of digital probesTesto 440 Hot Wire Kit in detailNo task is too challenging, no application too specialized: the testo 440 combines a compact hand-held measuring instrument with intuitive measurement menus and a wide selection of air velocity and IAQ probes (please order separately) ??Clearly structured measurement menus: the volume flow is precisely calculated thanks to convenient input of the size and geometry of the duct cross-section. Timed and multi-point mean calculation, average volume flow, current reading and min./max. values are displayed ??Other practical measurement menus, e.g. long-term measurement, volume flow measurement with a funnel, etc. ??Easy storage and evaluation of measurement data. Measurement data memory for up to 7500 measurement protocols, which can be read via a USB port and further processed as a CSV file on the computer (e.g. with Excel) ??Practical magnets for easy attachment of the measuring instrument to metal surfaces (e.g. ducts) ??Automatic detection of probes, e.g. hot wire probe ??Large, backlit colour display ??Hot wire probe (Ø 9 mm) including temperature sensor: ??Use the hot wire probe to measure air velocity, volume flow and air temperature in ventilation ducts ??Accurate measurements from 0 to 30 m/s and -20 to +70 °C thanks to the robust sensor and automatic absolute pressure compensation ??Telescope that can be extended to 0.85 m, with scaling, makes it easy to measure in ventilation ducts
