Why Mesa’s Defender Series?

» High accuracy. Calibrators in Mesa’s Defender Series are backed by Proven DryCal technology and have a reading uncertainty of less than 1%.

» Durability. All DryCal calibrators are field-proven and have provided IH professionals with reliable performance for decades.

» Real-time flow data. Calibrator flow data is captured in real-time with our DryCal Pro software, directly uploaded to a PC, and exported to a Microsoft environment.

» Convenient mail-in factory calibration. An annual NIST-traceable calibration by Mesa’s ISO-accredited facility provides a defensible audit trail and full refurbishment.

» Trusted accreditation. Mesa Labs is a fully accredited ISO-17025 facility with a 0.08% Scope of Accreditation for gas flow by NVLAP of NIST.

All Defender series products offer single, continuous, and burst reading options. The series is highlighted as a calibration method in the OSHA Technical Manual.
