Imagine creatures carefully covered in double layers from head to toe moving methodically in controlled environments. No, it is not a science fiction movie. These are commonly used scenes from field calibration. That is, calibration of measuring equipment on site at customers’ premises.– We never really know what to expect and what will happen, says calibration engineer Linda Wiman with a laugh.<\/p>\n\n\n\n

Field calibration is done at companies that either cannot do without their sensors and data loggers or have fixed measuring equipment that is difficult and time-consuming to remove. Linda Wiman and her colleagues in the calibration team at Nordtec go to these customers around Sweden. They carry high-precision lab instruments that are used for comparative measurements of customers’ measuring equipment.These comparison instruments are sensitive to transportation. To ensure their reliability, Linda makes a comparison measurement in an ice bath before going on a field mission.– Then we repeat the same measurement when we are back in the office again, to see if the measurement accuracy has changed. For moisture sensors, we check them in a similar way to measure accuracy before and after the customer visit,” says Linda.Depending on the nature and scope of the mission, different amounts of equipment and manpower are needed. If it’s too much and too heavy to do by herself, Linda needs the support of one or more colleagues.– If it is an accredited field calibration of both humidity and temperature, it will be quite a lot of equipment. For example, we have a humidity chamber with its own large special bag on wheels. And for temperature measurements we have a block oven which is also transported in a large bag.<\/p>\n\n\n\n
