Description
Climate measuring device, testo 440 basic, Incl. USB cable, calibration protocol and batteries. Without probe, please order separately.
One measuring device for all climate-relevant parameters (°C, % RH, m/s, hPa, CO, CO2, lux). Expandable with a large selection of digital probes, smart probes or numerous temperature probes. For more detailed information, see the data sheet in the download area.
Characteristics of the unit:
- Automatic probe detection. No need to manually reset the parameters when changing probes; up to three probes (digital or analogue) can be connected (1x Bluetooth®, 1x TUC, 1x mini TE)
- Intuitive operation with clearly structured measurement menus and graphic display with parallel display of three measured values
- With internal memory for up to 7500 measurement logs, data readout via USB interface, export as CSV file
- Greater convenience and less cable clutter thanks to cordless measuring with Bluetooth® probes (range max. 20 m)
NTC, Pt 100 and TE temperature gauges can all be connected.
- Measuring range of the device for NTC: -40 to +150 °C
- Measuring range of the device for TE: -200 to +1370 °C
- Measuring range of the device for Pt 100 (digital): see sensor data
- Note: The actual measuring range also depends on the measuring range of the respective temperature gauge
Delivery incl. USB cable, calibration protocol and batteries. Without probe, please order separately.
