Description
testo 535 digital CO2 measuring instrument with app connection is a compact meter for determining the carbon dioxide content of indoor air, a decisive parameter for room air quality and comfort. Long-term stable infrared sensor technology keeps measured values reproducible and comparable over extended periods, making the instrument ideal for recurring comparative measurements. Time and point mean value calculation is performed directly in the meter, supporting efficient evaluation without external tools. Display of measured values as table or graph, storage of results and documentation are handled by the testo Smart App; the app also allows individual configuration of the instrument and turns a smartphone into a second display. This workflow delivers rapid, precise CO2 results for healthy indoor climate assessments. Supplied as 1 pc from manufacturer Testo, the robust handheld unit suits facility managers, HVAC specialists and occupational health professionals who need reliable carbon dioxide data for comfort and air-quality evaluations in occupied spaces. Compact construction and app-supported documentation streamline routine indoor air checks.

Questions about testo 535 – Digital CO? measuring ,, instrument with App connection
What is this article?
testo 535 – Digital CO? measuring ,, instrument with App connection is the article on this page. Luminix Health distributes Testo for laboratory use. It sits in Digital thermometers, inside Temperature measurement, in Lab instruments.
A digital thermometer is a display plus a sensor. The resolution on the screen can be finer than the accuracy. The stated accuracy and the calibration point are what the number is worth. The probe type has to be the one the meter expects.
A thermometer reports a temperature. A liquid-in-glass thermometer is a calibrated column. A digital thermometer is a sensor and a display, and the sensor, not the display, is what is calibrated. An infrared thermometer reads a surface and depends on emissivity. A data logger stores the reading over time. Without a stated uncertainty and a calibration point, the number is only an indication. The scale is maintained by the BIPM and compared by EURAMET. Accreditation is BELAC.
