MesaLabs DryCal Defender 530+ (L, M, H Flow Ranges)
The MesaLabs DryCal Defender 530+ is a true Primary Standard calibrator using dry-piston swept volume technology. The Defender 530+ accuracy is ±1% of reading at flow rates from 5 ml/min to 30,000 mL/min while measuring temperature and pressure and calculating flow at standard conditions; ±0.75% volumetrically. The Defender 530+ instruments are easy to use, fast responding, hands-free calibrators for accurately setting flow rates of air sampling pumps and calibrating other instruments.
MesaLabs Defenders 530+ are compact, light weight and ideal for use in both the laboratory and in the field. The tough plastic case has molded rubberized hand grips for ease of handling. The front of the case has a clear plastic window for visual observation of the measuring cell. The top of the case has a back-lighted display and multi-function control button for on/off and navigation of the operating menu.
DryCal instruments are manufactured and calibrated by MesaLabs in the United States. MesaLabs is accredited to the ISO 17025, ANSI Z540, and NIST Handbook 150 standards. Traceability to the International System of Units (SI) and NIST is verified by accreditation to the ISO/IEC 17025 by NVLAP under Code 200661-0.
DryCal Pro Software
DryCal Pro software captures flow data from your DryCal directly to a PC and you can export the data to a Microsoft environment. It also allows real-time flow data monitoring and graphing along with allowing you to enter flow rates from sampling pumps or other flow source and calibrate the flow source. DryCal Pro is free and can be downloaded from MesaLabs.

Warranty
The standard Mesa-Bios Warranty is one year from date of purchase for the instrument, 6 months for the battery.
Annual Service Package (purchased separately)
The annual service and calibration service includes full product refurbishment each time the instrument is returned including cleaning and replacing all filters and seals, and battery test and replacement if needed. Any firmware or hardware upgrades are also installed at that time as part of the process. (Some upgrades may incurr an extra charge) The calibration includes 3-point flow calibration. The NIST-traceable certificate returned with the instrument includes pre- and post- calibration data. These data are also stored in Mesa-Bios’ calibration database for future reference
Ordering information
When ordering please indicate your selection of Low, Medium or High flow range.
