Instrument for long-term measurement and parallel determination of CO₂ concentration, humidity, air temperature and degree of turbulence in workplaces.
- One measuring instrument for all climate-related parameters
- Intuitive: Clearly structured measurement menu
- Convenient: wireless probe, internal data storage and USB port for data export
- Versatile: measuring instrument can be expanded with a large portfolio of digital probes
Calculation of wet bulb temperature, dew point and absolute humidity – determination of the degree of turbulence and draught risk according to EN ISO 7730 / ASHRAE 55
Use this practical Indoor Comfort ComboKit to handle all relevant measurements in order to evaluate the indoor air quality in indoor areas and to determine the draught risk and degree of turbulence in workplaces. The testo 440 air velocity and IAQ measuring instrument, the CO2 probe with Bluetooth® including temperature and humidity sensor and the turbulence probe are all safely stowed away in the case.
Connectable probes: 1 x digital probe with cable or 1 x Temperature NTC TUC, 1 x digital Bluetooth probe or testo Smart Probe, 1 x Temperature TC Type K
Interface: Bluetooth®; USB
Delivery information: Supplied with testo 440 air velocity and IAQ measuring instrument, three AA batteries, USB cable, and calibration protocol (TEST0560.4401), CO2 probe* with Bluetooth and humidity/temperature sensor (consisting of CO₂ probe head and Bluetooth handle), four AA batteries, table stand, and calibration protocol (TEST0632.1551), turbulence probe with fixed cable (length 1.4 m) and calibration protocol (TEST0628.0152), combi-case for testo 440 and multiple probes (TEST0516.4401)
Caution: * Do not use the probe in condensing atmospheres (> 80% RH at ≤ 30 °C for > 12 h / > 60% RH at > 30 °C for > 12 h)
