- 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. “NVLAP Lab Code 200661-0”
