Description

MesaLabs DryCal Defender 520 (L, M, H Flow Ranges)

The MesaLabs DryCal Defender 520 is a true Primary Standard calibrator using dry-piston swept volume technology. The Defender 520 accuracy is ±1% of reading at flow rates from 5 ml/min to 30,000 mL/min. The Defender 520 also measures temperature and pressure of the gas flow. These instruments are easy to use and fast responding; are hands-free for accurately setting flow rates of air sampling pumps and calibrating other instruments.

MesaLabs Defenders 520 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-lit 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 Sates. 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
