The PSL Rheotek RPV-1 Pulp & Cellulose viscometer system automatically measures the viscosity of a solution of pulp, paper or cellulose dissolved in cupriethylenediamine (also known as CED or Cuene). The RPV-1 Pulp & Cellulose viscometer automates the manual steps set out in standard methods, minimizing the variability of results.

Systems can be configured with 1 to 4 measuring positions. Other options include sample preparation, sample agitation and auto sampler.
Flow times are measured automatically using ASTM Ubbelohde viscometer tubes supplied with ISO 17025 certificates of calibration.

Cleaning is carried out in-situ utilizing solvents and a safe vacuum system.
The comprehensive RPV-1 software program records all measurement data as well as calculating a wide range of results including relative viscosity, intrinsic viscosity (Limiting Viscosity Number), degree of polymerization (DP), K value, kinematic viscosity (mm²/s) and dynamic viscosity (mPa.s).
PSL Viscometer tube types: AKV Ubbelohde or AKV Cannon Fenske Routine.
