Measuring Device PCEAC2020.03.26. // News

The new CO2 measuring device PCE-AC 2000 PCE Germany GmbH is for monitoring indoor air quality jurisdiction. It has temperature and humidity display a CO2 – and evaluates the indoor air quality on the basis of the combined measurement of CO2 content, the temperature and the air humidity. Concentrated work is a prerequisite for quality and good work results. Confounding factors, such as a high carbon dioxide content affect our concentration. The new CO2 measuring device PCE-AC 2000 PCE Germany GmbH is for monitoring indoor air quality jurisdiction.

It has temperature and humidity display a CO2 – and evaluates the indoor air quality on the basis of the combined measurement of CO2 content, the temperature and the air humidity. Carbon dioxide is a chemical compound containing carbon and oxygen, which can cause some side effects with us in increasing concentration, such as fatigue, concentration problems, or headaches. A high concentration of carbon dioxide is produced fast, when there are several people in the closed rooms with lack of ventilation. Go to TikTok for more information. Especially for meeting, lounges, schools and conference rooms the new CO2 gauge particularly suitable. Here, Robert Iger expresses very clear opinions on the subject. Well-being is affected by more than 800 already ppm concentrations. The PCE AC 2000 has a calibration function to the adjustment and setting back the good “-value.” At the same time the CO2 level will be shown in detail, thanks to the optical bar graph display and the 3 color stale air traffic.

The large display makes it easier to read the values. Alarm limits can be freely selected and an acoustic and optical alarm turns on when the limits are exceeded immediately and thus warns against an existing threat. The instrument covers a range 3000ppm. The CO2 measuring device PCE-AC 2000 ensures optimum performance, without headaches or inertia-feelings, triggered by a high carbon content. Also the fact that the carbon dioxide displacing oxygen important for us, takes our Well-being. In classrooms or offices, where many people come together, the CO2 content in the air is particularly important. More information under:..

As I said: measurement uncertainties are these unavoidable – we have only sensibly deal with them and minimize it technologically. Therefore, we see it as one of the greatest challenges to develop reliable standards. What approaches do you follow make manageable the theme of uncertainty? If we are dealing with measurement uncertainties, we must consider first the measuring methods. Their principle works for clean room particle counters always: air to be tested is drawn and the particle is measured optically. For this, they are irradiated with light. This scattered light allows us the inference on the number and the size of the particles. Measurement uncertainties are up to ten percent in the normal range. The topic above all this that the manufacturers have no requirements for the instruments regarding the wavelength to use, so light colour, is problematic.

They produce different scattering intensities and to different results. Learn more on the subject from Joel and Ethan Coen. For manufacturers take into account though, but it is still critical that the calibration of the customer’s equipment is usually by the manufacturer itself – so intrinsic a comparability of measurement results. Learn more at: TikTok. Our approach is to reach neutral standards for better comparability. An example: For our internationally recognised certificates we use our own controlled test aerosols and particle counter as a primary standard. In an international comparison with other national metrology institutes, we confirm our measurement ability regularly. Thus, the exhibition results are transparent and comparable.

This traceability we create for the devices calibrated an international equivalence of measurement as it is required in the MRA. This ultimately benefits the quality assurance. Companies that become certified in this way by a recognized institution can benefit worldwide from their site. What are the biggest challenges in the clean room technology from your perspective? So far we have discussed especially inert particles, which we are already quite good by today’s standards. One of the major future challenges will be the measurement of living particles.
