ML-800 Series
Legacy Metrology Platform & DryCal 800 Flow Cells
The ML-800 Metrology Series established Mesa Labs' modular high-precision primary gas flow platform, combining Proven DryCal® Technology with interchangeable flow cells for direct gas flow measurement from 0.5 sccm to 100 slpm.
The current generation of this platform is the DryCal® 800. It retains the modular five-cell concept and the established 200-800 flow-cell range while adding a modern touchscreen base, USB and RS-232 communication and updated electronics.
Existing ML-800 instruments continue to be supported for calibration and service. For new systems and current product specifications, please refer to the DryCal 800.

From ML-800 to DryCal 800
The DryCal 800 modernized the ML-800 platform with a new low-profile electronic base while retaining compatibility with the established ML-800 flow cells and software.
- 4.3" resistive touchscreen
- USB and RS-232 interfaces
- Firmware updates through the communication port
- High-efficiency electronics with minimal heat generation
- Low-profile design for improved stability
- Compatible with existing ML-800 flow cells and software
Service for Existing ML-800 Instruments
Mesa Labs continues to list the ML-800 among the DryCal instruments supported for calibration and service. Annual calibration is recommended as a periodic quality assurance measure and to maintain a documented, traceable calibration history.
