Carry out measurements without any annoying cables: use the kit to handle all relevant measurements in ventilation ducts and at air/ceiling outlets. You will receive the testo 440 dP air velocity and IAQ measuring instrument including differential pressure sensor and the 100 mm vane probe head and hot wire probe head (Ø 9 mm) for attachment to the universal Bluetooth® handle supplied. To make measurements more convenient, both probe heads can be combined with the telescope included in the kit. The equipment can be transported safely and conveniently in the robust case.
testo 440 dP - Air velocity and IAQ measuring instrument including differential pressure sensor Order-Nr. 0560 4402 Intuitive: clearly structured measurement menus for volume flow, K-factor, degree of turbulence, cooling/heating output, mould detection and long-term measurement, such as CO₂ Wireless: Bluetooth® probes for extra convenience when measuring and less cable clutter in the measuring case (please order probes separately)
Vane probe (Ø 100 mm, digital) - with Bluetooth® including temperature sensor Order-Nr. 0635 9431 Intuitive: clearly structured measurement menu for volume flow and parallel determination of air velocity, volume flow and air temperature Precise: get the right results in next to no time, even in turbulent air flow – using the optionally available funnel set and volume flow straightener
Hot wire probe head including temperature and humidity sensor Order-Nr. 0635 1570 Intuitive: parallel determination of relative humidity and air temperature in indoor areas, including long-term measurement Precise: includes absolute pressure compensation, calculation of wet bulb temperature, dew point and absolute humidity
Extendable telescope (up to 1 m in length) for flow probes Order-Nr. 0554 0960 The telescope is 1.0 m long when extended Easy-to-read scaling for easy measurement in ducts
