Item #EMSS0050G — Seraphin Series “M” Prover – 50 gal

Seraphin® High Sensitivity Neck Provers are calibrated by NVLAP laboratory facilities in order to guarantee the least uncertainty for your liquid measuring calculations.

High resolution test measures and provers are designed with a small diameter neck and are used to achieve a grater neck volume resolution. High sensitivity equipment is typically used in a standards laboratory setting but may also be used in field settings. Seraphin® High sensitivity Neck Provers are the de facto industry standard for waterdraw calibration of displacement type provers.

Built to NIST Handbook 105-3, Measurement Canada, and OIML R-120 specifications, Seraphin® Provers Provide an accurate and repeatable standard to calibrate liquid meters, and Provers. A high resolution stainless steel standard has a narrow neck and whose accuracy and uncertainty has been determined by gravimetric calibration in relation to traceable working mass standards or whose accuracy and uncertainty has been determined volumetrically in relation to high resolution standard tested gravimetrically.
