Dial Reading The BROOKFIELD VISCOMETER… the world standard, unsurpassed in reputation and value. The Brookfield Dial Reading Viscometer is a rugged, mechanically simple measurement instrument. Its calibration spring is unaffected by long use or extreme environmental conditions, retaining its calibration indefinitely. Readings from the viscometer dial can be directly converted into centipoise units (cP); no timing or involved calculations are required. Accurate reproducible viscosity determinations within ±1.0% of the range in use can usually be made in less than 30 seconds. Explosion Proof Models All Dial Reading models are available in either explosion-proof construction for U.L. Class 1, Group D locations or the standard Viscometer can be supplied with a non-arcing mercury switch. NIST traceable viscosity standards available Models LVF, LVT, RVF, RVT, HAT, and HBT available… Model Selection Table Standard Fluids
