RAD?CO Air Flow Calibrators are the most durable and repeatable calibration devices available. RAD?CO calibrators are constructed of a precision machined aluminum venturi tube and an appropriately ranged intelligent digital meter mounted in a rugged steel case. Simple, cost effective and consistently accurate year after year.

RAD?CO Air Flow Calibrators are available calibrated in cubic feet per minute or in liters per minute. Each calibrator is individually calibrated to an air flow instrumentation system whose calibration is certified and traceable to the National Institute of Standards and Technology (NIST). The RAD?CO Air Flow Calibrators are guaranteed to an accuracy of better than +5%, referenced to 29.92 inches of mercury and 70°F. A Certificate of Calibration is supplied with each calibrator.

RAD?CO maintains an Air Flow Calibrator recertification and repair service for all RAD?CO units. Similar units manufactured by competitors can also be serviced at our facility. Special calibrations are available upon request. An assortment of adaptors is available which mate the calibrators to all RAD?CO Sample Holders.

Specifications

Twenty-five Years of Proven Reliability

RAD?CO Air Flow Calibrators are the most durable and repeatable calibration devices available. RAD?CO calibrators are constructed of a precision machined aluminum venturi tube and an appropriately ranged magnehelic gauge mounted in a rugged steel case. Simple, cost effective and consistently accurate year after year.

RAD?CO Air Flow Calibrators are available calibrated in cubic feet per minute or in liters per minute. Dual calibrations are available on special request. Each calibrator is individually calibrated to an air flow instrumentation system whose calibration is certified and traceable to the National Institute of Standards and Technology (NIST). The RAD?CO Air Flow Calibrators are guaranteed to an accuracy of better than +5% FS, referenced to 29.92 inches of mercury and 70°F. A Certificate of Calibration is supplied with each air flow calibrator.

RAD?CO maintains an Air Flow Calibrator recertification and repair service for all RAD?CO units. Similar units manufactured by competitors can also be serviced at our facility. Special calibrations are available upon request. An assortment of adaptors are available which mate the calibrators to various RAD?CO Sample Holders.
