Flow Range: 12-12,000 ml/min.
The 10-100-1000 ml is our largest triple stage flow meter. It is a three-stage design that measures 10 ml in the first stage, 100 ml in the second stage, & 1000 ml in the third stage.
Standard: Not Traceable or Certified.
NIST Traceable: Serialized and calibrated with instruments traceable to the National Institute of Standards and Technology. The NIST Traceable Bubble-O-Meters have a potential error of 3 -5%, depending on the stage volume.
A2LA Accredited and NIST Traceable: Serialized with all calibrations subcontracted to an independent Metrology Laboratory that is certified to 9001:2000 ISO, accredited by A2LA to ISO/IEC 17025 and ANSI/NCSL Z540.1. The Bubble-O-Meters are calibrated in accordance with ASTM E694. Certified uncertainty of 0.25% across any range.
