High-Precision Primary Flow Standards

For Laboratory and Industrial Process Control Applications

As a replacement for the ML-800 base, our new DryCal 800 base has been enhanced with:

  • A 4.3” Resistive Touch Screen
  • USB and RS-232 Interfaces
  • Firmware Updates through a Communication Port (No Disassembly Required)
  • New High Efficiency Electronics with Minimal Heat Generation (Eliminates a Potential Source of Measurement Uncertainty)
  • Low Profile Design (Provides Increased Stability)
  • Compatible with All Existing ML-800 Flow Cells and Software

With the new DryCal 800 base, you still receive the same exceptional low uncertainties you have come to expect from our high-precision primary flow standards. It meets the most stringent laboratory and industrial process control requirements, making it the ideal solution for demanding process control and calibration professionals around the world:

  • Precise, Primary Measurements
  • Demonstrated On-Site Durability
  • Broad Flow Range – 0.5 sccm to 100 slpm

The DryCal 800 Series combines our Proven DryCal Technology with interchangeable flow cells to offer a broad flow range that fits the needs of your application. Combine our DryCal primary piston provers with our new Integrator Pro to set up an analog MFC and MFM calibration station and power to control up to two voltage and two current mass flow devices at the same time.

For use with non-corrosive, non-condensing, non-combustible gases, less than 70% humidity.
