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 15°). As a standard we make the calibration at a constant wind-speed of 10m/sec but we are flexible in following any request if necessary.

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.

For applications inside buildings or outside in ‘the field’ we provide a complete range of IoT data loggers: long distance data transmission.

Our LoRa data loggers have a wide choice of standard sensors for measurements like temperature, humidity, dew point, CO2, differential pressure…and many more. Next to this, it is possible to integrate (third-party) sensors that have Modbus communication or analog outputs.

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 the size, these can be divided in different ranges with the common factor that, once inhaled, they are responsible for a large variety of health disease to a lesser or greater degree.
