RPV-1/SP Electrical Papers Viscometer System with Sample Preparation. PSL-Rheotek

RPV-1 Electrical Paper Viscometer


Integrated sample preparation and glass capillary viscometer system suitable for measuring  the average
viscometric degree of polymerization of new and aged cellulosic electrical (papers) insulating materials
typically used in transformer, cable or capacitor manufacturing.
RPV-1 Electrical papers viscometer systems can be configured with a unique nitrogen purge system in
order to ensure that samples are protected from oxidation during both the sample preparation and
viscosity test.

Product Description

Details

The PSL Rheotek RPV-1 Electrical Papers viscometer system automatically measures the viscosity
of a solution of paper in Cuen (cupriethylenediamine, CED)
The RPV-1 Electrical Papers viscometer automates the manual steps set out in standard methods,
minimizing the variability of results.
The integrated Sample Preparation system is supplied complete with two syringe pumps, precision
balance and voice prompting software. Samples are prepared on a weight to weight basis using <
pre-programmed methods.
Systems can be configured with 1 to 4 measuring positions.
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 EP software program records all measurement data as well as calculating
a wide range of results including specific viscosity, intrinsic viscosity and degree of polymerization.

Typical applications and configurations 
Test Method Solvent Concentration Temperature RPV-1 EP measuring positions
IEC 60450 Cuen 0.05 to 0.8% 20°C 1 to 4
ASTM D4243 CED (Cuen) 0.05 to 0.8% 20°C 1 to 4
