Gas flow calibrator Defender

pressure

High accuracy. Calibrators in Mesa’s DefenderTM 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.
