testo 440 - CO₂ set with Bluetooth®

With the testo 440 climate measuring instrument, you can measure and save all climate-related parameters in combination with high-quality probes (please order probes separately). Up to 3 probes can be connected at the same time: a Bluetooth probe, a wired probe and a temperature sensor with thermocouple type K connection. Automatic probe recognition and clearly structured measurement menus ensure extremely easy operation and make your everyday work easier. Measurements in just a few clicks with the testo 440 multifunction measuring meter Carry out your measurements quickly and easily: the climate measuring instrument automatically recognizes every connected probe. This saves you having to manually reset the parameters when changing the probe. Clearly structured measurement menus for volume flow measurement in the duct/at the outlet, funnel measurement, degree of turbulence measurement, determination of the cooling/heating capacity; Mold indication and long-term measurement support you optimally in your daily work. Wireless and space-saving: more applications, less equipment Unlimited versatility: A universal handle can be connected to all probe heads – so you master more applications with less equipment and save space. The Bluetooth handle ensures more comfort during your measurement and less cable clutter in the case. It enables measurements without a disruptive cable connection and transmits readings up to a distance of 20 m. Or use the cable handle as a practical alternative to connect testo probe heads. This is an advantage when Bluetooth signals are not allowed. Practical measurement data management The multifunction measuring device stores up to a maximum of 7500 measurement logs, which can be read out via a USB interface and further processed as a CSV file on your computer (e.g. with Excel). With the testo BLUETOOTH/IRDA printer (please order separately) you have the option; to produce a log printout of the measurement data directly on site. Intelligent calibration concept for maximum precision With our digital probes, you can rely on precise measurement results, since the measurement uncertainty of the measuring device is eliminated. For calibration, just send in the probes. In this way, the multifunction measuring device can always be used. Advantages of measuring with the testo 440 climate measuring instrument Precise and reliable in the duct and at the air outlet Wide range of connectable probes: hot wire and vane probe (Ø 16 mm) for measurements in the duct; Large vane probes with Ø 100 mm for measurements on air/ceiling outlets Calculate volume flow quickly: simply configure the dimensions and geometry of the duct cross-section in the measurement menu and have the volume flow displayed directly on the measuring device You can measure conveniently even in particularly large ducts. Because the extendable telescope of the hot wire and vane probe (Ø 16 mm) with universal handle can also be extended with the telescope extension – you can achieve a total length of 2 meters You can carry out measurements on air/ceiling outlets effortlessly and without a ladder. Equip the vane probe (Ø 100 mm) with the extendable telescope with a 90° angle and, if necessary, with the telescope extension (both available separately) vane probes in connection with the testovent measuring funnels and rectifiers for testing supply and exhaust air on disk valves, ventilation grilles and twist outlets Practical Bluetooth interface: measure with the flow probes without an annoying cable, operate the measuring device by pressing the button on the handle of the probe, e.g. start or stop the averaging over time With the practical magnets, the multifunction measuring device can be securely attached to metal surfaces (e.g. ventilation duct) attach Long-term monitoring of indoor air quality The right probe for your needs: Probes for CO 2 , CO, air temperature and humidity are available as a variant with Bluetooth or with a permanently connected cable Simple operation: Enter the measurement duration and interval in the menu for long-term measurement and track the course of the day Int internal memory for up to 7500 measurement protocols Degree of turbulence measurement according to EN ISO 7730 / ASHRAE 55 Achieve high accuracy even at low flow velocities with the degree of turbulence probe Automatic calculation of draft risk and degree of turbulence according to EN ISO 7730/ASHRAE 55 For convenient measurements at different heights, we recommend using our Measuring tripod for comfort measurement. Positioning of the degree of turbulence probes in accordance with the standard is therefore particularly easy. Range of sensors for clean rooms and laboratories Laboratory fume hood probe for high-precision flow measurement in the fume hood The high-precision vane wheel probe (Ø 100 mm) is excellent for laminar flow Suitable for measurements in clean rooms. Available as a variant with Bluetooth or with a permanently connected cable High-precision temperature-humidity probe (06369771 or 0636 9772) with an accuracy of ±(0;6 %RH + 0.7 % of mv.) in the range of 0 … 90% RH for measuring humidity in clean rooms
