DryCal® Metrology Series
Accurate. The DryCal 800 has industry-leading accurate flow measurements down to 0.5 sccm. The DryCal 800 is more than 4x more accurate than most flow meters, giving you the ability to calibrate with confidence. Quality. Backed by our ISO 17025 accreditation by NVLAP of NIST. “NVLAP Lab Code 200661-0” Flexible. DryCal 800 consists of a base with a touchscreen and interchangeable cells to allow you to customize the standard for your specific needs. Gas-Species Independent. No gas-specific calibrations are required. Use the DryCal 800 with any non-corrosive, non-combustible gas. Portable. Small and lightweight so that you can easily change location compared to older flow standards. Dedicated. Mesa has dedicated pre- and post-application Sales Application Engineers available to help you pick the flow standard that’s right for you.

The Defender Series
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. "NVLAP Lab Code 200661-0"

T-EZ Pro® Cleaning Indicators
It is easy to use – just remove the T-EZ Pro from its package and attach it directly to the sieve tray. Thanks to the transparency of the plastic, there is no need to remove the indicator strip from its PCD for interpretation. However, it is possible to open the test body and archive the indicator for documentation purposes. True blood based soil formulation as a verification indicator Eliminate the risk of false negatives attributable to handling the indicator soil Easy-to-use, simply snap on to your existing mesh tray All in one, single use Possible to remove of the indicator from its PCD for protein tests

Bowie Dick Simulation Test
The Bowie Dick Simulation Test is a breakthrough reusable Process Challenge Device (PCD) that combines both Bowie-Dick and hollow load test requirements in a single system. Designed specifically for pharmaceutical and biotech manufacturing, this type 2 indicator system meets ISO 11140-1 standards and ensures comprehensive steam sterilizer performance verification while dramatically reducing environmental waste.
