All Macurco Nitrogen Dioxide detectors are factory calibrated when they are shipped to the customer. This calibration should be within specifications for 6 months to a year. Some jurisdictions, local standards, or customer preferences require periodic recalibrations. This Kit provides the means to fit those requirements. Macurco recommends checking the operation of the Macurco Nitrogen Dioxide detector every six months, either through use of the procedures given in the operating instructions or this Field Calibration Kit.
