ML One™

"Operation of the ML One™ is intuitive and simple, a typical gas flow measurement only requires the user to connect the gas flow and touch measure on the screen followed by start."

The Bios ML One™ provides primary gas flow measurement with an uncer- tainty of (0.15% of reading and +/-.01 ccm) across a flow range of 5 to 50,000 ccm. The ML OneTM is an all-in-one measurement instrument for use in a laboratory or transported on a cart for factory floor measurements. It is designed to measure corrosive gases compatible with wetted path materials: (304- 316 stainless steel, borosilicate glass, Teflon®, and AFLAS® elasto- meric). Three tubes sit horizontally in the instrument and are fitted with low mass – borosilicate glass pistons with a low friction coating that oscillate between two detectors to quickly and accurately measure gas flow rates.

  • Reliable - Over 20 years of Proven DryCal® Technology
  • Accurate - Backed by ISO17025; NVLAP accredited, ANSI Z-540, NIST Handbook 150
  • Flexible - Portable; bi-directional digital interface for automated control.
  • Convenient - Push button simplicity; dry - no mercury or other liquids
