Bios Defender 510 & 520 Calibrators | Volumetric Flow Measurement

Defender 510 and 520 calibrators are true primary flow meters and immune to flow source pulsation without the need for in-line dampers.  The Defender Series is more accurate and more repeatable than the older DryCal DC-Lite and DryCal DC-2.  Volumetric flow units may be set to ml, l, cc, or cf.  The Defender calibrators can be set to take individual readings, continuous hands-free readings, or set to read in user selectable time intervals. They can also be set to include up to one hundred readings in a group average.  Used for calibrating personal or environmental sampling pumps used in Industrial Hygiene, Environmental, Health and Safety abd monitoring for OSHA respirable dust, lead, asbestos, and mold applications.

Bios Defender 530+ Calibrator | Volumetric & Standardized Flow Measurements

The Defender 530+, with the ability to take both volumetric and standardized readings, is the latest addition to the popular Defender 510 and 520 line of Bios DryCal primary flow calibrators. Automatic correction of readings for temperature and pressure, rather than merely recording of ambient conditions, is essential for many applications such as calibrating mass flow meters and PM10 and PM2.5 environmental samplers. Took the place of the Definer 220 series calibrator with flow rates from 5 cc to 30 liters and an accuracy of ±1% percent for readings standardized for temperature and pressure and ±0.75% in volumetric flow.

MesaLabs FlexCal Precision Primary Flow Calibrator | Volumetric & Standardized Flow Measurements

The MesaLabs FlexCal series calibrator is a precision primary flow calibrator with flow ranges from 5ccm to 50 LPM with both volumetric and standardized flow measurement accuracy of 0.5% of the reading. An economical option for small analytical laboratories, research & development organizations, manufacturers and calibration labs that may not need the 0.15% accuracy of the DryCal 800 series calibrators.

PRODUCT DISCONTINUATION NOTICES

The DryCal DC-Lite and the DryCal DC-2 have been discontinued and superseded by the DryCal Defender 510, 520 & 530+ series of calibrators. MesaLabs will continue to support customers using DryCal DC-Lite with calibration & service until further notice. Effective January 1, 2018 all support for the DryCal DC-1 and DC-2 ended. Contact us for further information and any trade-in programs.

Bios Definer™ 220  Effective January 16th, 2017, Mesa Labs discontinued the Definer 220. The Definer 220 has been directly replaced by the new Defender 530+. Mesa will continue to accept RMAs for service and calibration of the Definer 220 dependent on the availability of parts. Please contact us regarding trade-in programs.

Bios DryCal DC-Lite^® Air Flow Calibrator Employed "frictionless" dry piston technology in rugged, pocketbook sized Air Flow Calibrator that is NIST traceable, true primary standard, even under field conditions. The Bios DryCal DC-Lite had five flow ranges of 10 to 500 ml/min,  50 ml/min to 2 L/min, 100 ml/min to 7 L/min, 20 ml/min to 20 L/min, 500 ml/min to 30 L/min.

January 2017 Note: MesaLabs will continue to support the DC-Lite series of calibrators with service and calibration. Please note that once the limited number of repair parts such as main boards are no longer in stock, your calibrator will not be able to be repaired. Please contact us regarding trade-in programs.

Bios DryCal DC-2^®  Air Flow Calibrator The DC-2 employed Bios' well known "frictionless" dry-piston technology in a rugged instrument that automatically corrected flow rates to Standard Temperature and Pressure Conditions (STP) suitable for field calibration of air sampling and mass flow monitoring instruments. Data could be logged using a PC via serial cable (RS232) or hard copy obtained from a printer (parallel port) As this product is discontinued, no service or repair is available for this product.
