Faced with the fear of Covid-19, all over the world, researchers are focused on finding solutions and tools to fight the virus. These include as well UV lamps and their capacity to inhibit viruses. According to recent studies, it appears that the application of UVC ultraviolet radiation used by the new LED lamps has proved to be highly effective....

The term Air Pollutants also known as Particulate Matter or PM it is used to indicate the mixture of solid particles and liquid droplets found in the air. Some of these particles are large enough to be seen with naked eye but many other are so small and fine that can only be detected through specific instruments. Depending on...

HD2013.3 is the newest update of our rain-detector, equipped with additional features like Modbus communication and analogue outputs. A simple but robust measurement made to do what it should do: to detect rain. What is interesting to see is what is being considered as ‘rain’. That depends a lot on the application. What some people call a ‘rain-event’ others...

Added to our calibration capabilities: calibration certificate on wind-direction. As we receive more and more request for not only wind-speed calibration but also for a calibration certificate on wind-direction, we have invested in this possibility. We can generate several calibration reports as a standard: starting from a 4 point calibration (per 90°), up to a 24 points calibration (per...

We as Delta OHM are so used to having extensive in-house ISO17025 calibration possibilities, that we sometimes forget how different this makes us from other suppliers. We do not just operate ‘a’ ISO17025 calibration facility. Our in-house ISO 17025 accredited Calibration Centre in fact consists of 6 independent laboratories; accredited for Air Speed, Temperature, Acoustic, Light, Pressure and Humidity....

UVC irradiance measurement is important to check equipment that emits UV-C. Disinfection when using UVC can be very efficient. The Ultra Violet C light is being used to disinfect water, air and surfaces. Important is that the correct dose of UV-C is used; only when having the correct dosing of UV-C makes the disinfection effective. All equipment as used...

Advanced KIT and Basic KIT: measuring LUX for LED and conventional light. Simple, accurate, no adjustments necessary to measure LED light. Ever been using a LUX meter to measure LED light? Maybe you recognize a very common effect that many already have discovered: the LED light seems to be a higher intensity than the conventional light, but still the...

In the Guide to Meteorological Instruments and Methods of Observation, the WMO has approved the possibility to use the so called ‘pyranometric method’ to calculate Sunshine Duration. This means that, next to the already frequently used method where a specific Sunshine Duration sensor is being used, in some cases it may be more efficient to use the measurement data...

An application that is getting more and more interesting all around the world, is the measurement of Building Vibration. Specifically: measuring the effect of vibration annoyance on the human body. Vibration in buildings can be an effect of machines that are installed in the building but it can also be vibration that is being generated by something from outside:...
