Bios DryCal DC-Lite Air Flow Calibrator, Bios Dry Cal DC Lite MesaLabs produces the replacement for the DryCal DC-Lite,the Defender 510, 520 and 530 dry primary flow meter design that offers low cost, light weight and ultra-compact size. The newer DryCal Defenders are immune to flow source pulsation without the need for in-line dampers.

It provides users with a primary flow standard for industrial hygiene, environmental and laboratory applications. The DryCal DC-Lite fits easily into a slim briefcase for convenient transport and in keeping with all DryCal flow meters; it eliminates the need for messy soap film solutions.

The DryCal DC-Lite used the patented DryCal near-frictionless piston technology and photo optic sensors to obtain volumetric flow readings quickly and accurately.  Housed in a small 5" x 5" x 2.75" case, each unit is power-packed with a variety of popular user conveniences such as AC/DC operation, a large alphanumeric LCD, push-button read and auto-read functions, automatic shut-off and a parallel printer port that interfaced with standard IBM compatible printers.

Kit Includes: DryCal DC-Lite unit, one flow cell range, single-station charger, tubing and manual.

  • Primary Flow Standard
  • Certified NIST Traceable
  • 5-Minute Auto Shut-Off
  • Simple Push-Button Operation
  • Immune to Flow Source Pulsation
  • Fast & Accurate
Simple Operation
The Bios DryCal DC-Lite provides the user with accurate volumetric flow readings with the push of a button. No training required.

Continuous Auto-Mode
DryCal DC-Lite flow readings can be taken continuously, in the auto mode, providing hands-free operation. This feature enables the user to quickly adjust the flow source to a precise flow rate saving time and money.

Immune to Flow Source Pulsation
DryCal DC-Lite  needs NO in-line dampers.

Flow Cell Volume Certified NIST Traceable
The DryCal DC-Lite flow cell is made of dimensionally stable Borosilicate glass and is manufactured and characterized to ±0.00005 inch tolerance. At BIOS each cylinder is re-measured with NIST traceable standards and certifying documentation is provided for each unit.

Crystal Timing Mechanism is Tested With NIST Traceable Frequency Counter
That is periodically re-certified by a NIST traceable laboratory.

Patented Graphite Composite Piston Assembly
DryCal DC-Lite's patented graphite composite piston assembly eliminates the inherent inaccuracies and mess associated with bubble soap.

Sealed Lead Acid Battery
Eliminates NiCad battery problems; memory effect and battery burnout from overcharging. Allows AC/DC operation. The DryCal DC-Lite can be used while charging.

Alphanumeric Display (LCD)
Indicates flow rate, flow average and number of readings included in average.
(10 readings per averaging sequence)

5-Minute Auto Shut-Off
Preserve battery life and ensure deployment resources with Bios DryCal DC-Lite's 5-minute auto shut-off function.

Built-In Flow Cell Integrity Test
Quality assurance self-test allows user to periodically verify proper flow cell integrity.

DryCal Has Been Tested By NIST
And the Japanese National Laboratory of Metrology and was found to be within ±0.2% of their transfer standards.

Built-in Parallel Printer Port
Interfaces with IBM compatible printers.

Battery System: 6V Rechargeable, Sealed lead-acid, 6-8 hours typical operation
AC Battery Charger: Wall-mounted single-station
Input: 100 to 120 VAC, 50 to 60 Hz
Output: 12VDC, 2.5mm charger plug, center positive (Optional: 200 to 240 VAC, 50 to 60 Hz) 
The charger can be used for AC operation.
Note: The standard 120V charger receptacle prongs fit the U.S., Canada, and Japan, while the standard 240V prongs fit much of Europe (with the exception of the U.K). For those requiring alternate prongs, there is an adaptable universal charger that will handle voltage from 100 to 240, with interchangeable prongs to fit usage in almost any country available for an additional cost. For pricing information, please contact us. If you wish to receive the universal charger with your DryCal orders, please provide a description or image of the prong requirement.
