The climate measuring instruments testo 440 combine the benefits of a compact handheld device with intuitive measurement menus and a comprehensive selection of air velocity & IAQ probes. Both the digital Testo Smart Probes and numerous Testo temperature probes can be connected. Clearly structured menus for measuring volume flow in ducts/at outlets, degree of turbulence, cooling/heating load, mould indication and logging mode are stored on the instrument.The testo 440 dP also has an integrated differential pressure sensor. This makes measurements at filters as well as Pitot tube and K-factor measurements possible.USB interface for data export and optional printout of measuring valuesUp to 3 probes can be connectedParallel display of 3 measuring valuesBluetooth probes for measuring convenience and easy storage in the caseUniversal handle for all probesMeasurement of the following parameters are possible: °C, % r.h., CO, CO2, m/s, Lux, hPaPlease order probes separately.SpecificationsTemperature measuring range (NTC):-40 ... +150 °CAccuracy:±0.4 °C (-40 ... -25.1 °C) ±0.3 °C (-25 ... +74.9 °C) ±0.4 °C (+75 ... +99.9 °C) ±0.5 % of measured value (remaining range)Resolution:0.1 °CTemperature measuring range (TE Typ K):-200 ... +1370 °CAccuracy:±(0.3 °C + 0.3 % of measured value)Resolution:0.1 °CDifferential pressure measuring range testo 440 dP:-150 ... +1500 hPaAccuracy:±0.05 hPa (0 ... +1.00 hPa) ±0.2 hPa + 1.5 % of measured value (+1.01 ... +150 hPa)Resolution:0,01 hPaMemory:7500 measurement protocolsOperating / storage temperature:-20 ... +50 °CDimensions (W x D x H):65 x 32 x 154 mmWeight:250 gPower supply:3 x Mignon, Type AA
