TQC Sheen Cone and Plate Viscometer CP1

The TQC Sheen Cone and Plate Viscometer CP1 (SKU DV2500) is a dynamic viscosity instrument for non-Newtonian paints, coatings, inks and cosmetics. Manufactured by our TQC Sheen paint testing specialist brand, the CP1 tightly controls the shear rate applied to the sample – 10,000 s⁻¹ per BS 3900-A7 and ISO 2884, or 12,000 s⁻¹ per ASTM D4287 – shear rates that closely represent brush and roller paint application in the real world. 

Used by paints and coatings R&D formulators developing new coating chemistries, ink manufacturers, non-Newtonian fluids specialists, cosmetics and personal-care R&D labs, adhesive formulators, and coatings QC teams verifying batch consistency – the CP1 delivers repeatable dynamic viscosity readings at defined shear rates, which conventional Krebs-unit or flow-cup instruments cannot provide. 

The sample is placed on a temperature-controlled plate (5°C to 65°C) – eliminating the biggest source of viscosity measurement variability. A microprocessor-controlled motor lowers the cone gently onto the sample, applies the selected shear rate, measures the resulting torque and displays viscosity on the front LCD. A manual or handle-operated automatic operation mode covers different lab workflow preferences. Note: the CP1 Base Unit is supplied without a cone kit – cone kits are ordered separately based on the viscosity range of your samples. 

Why it matters

Defensible dynamic viscosity data to BS, ISO and ASTM shear-rate specifications. Compliant with BS 3900-A7, ISO 2884 and ASTM D4287 – so R&D formulation data and QC batch results stand up under coating manufacturer specification audit, end-customer QC review and coating project acceptance. 

Tightly controlled shear rate represents real-world coating application. 10,000 s⁻¹ (BS/ISO) or 12,000 s⁻¹ (ASTM) shear rates closely match the shear conditions a paint experiences under brush or roller application. Static flow-cup and Krebs-unit measurements do not capture this – the CP1 is the reference method for R&D specialists comparing formulations that will behave differently at low vs high shear. 

Temperature-controlled plate 5-65°C eliminates the biggest source of viscosity variability. Viscosity is highly temperature-sensitive – a few degrees changes readings by measurable amounts. The CP1 controls the sample temperature at the plate, so batch-to-batch and lab-to-lab comparisons stay valid across ambient temperature variation. 

Standards Compliance

The TQC Sheen Cone and Plate Viscometer CP1 is designed to support dynamic viscosity testing to the following international standards: 

• ASTM D4287 – High-Shear Viscosity of Paints and Related Materials Using ICI Cone-and-Plate Viscometer (12,000 s⁻¹ shear rate) 
• BS 3900-A7 – Methods of test for paints – Determination of viscosity of paints by rotational viscometry (10,000 s⁻¹ shear rate) 
• ISO 2884 – Paints and varnishes – Determination of viscosity using rotatory viscometers (10,000 s⁻¹ shear rate) 

How the cone and plate method works

The cone and plate method is a controlled-shear-rate rotational viscometry technique specifically designed for non-Newtonian fluids where viscosity changes with shear rate: 

• A small sample volume is placed on a flat, temperature-controlled plate. 
• A precision cone (selected for your viscosity range) is lowered gently onto the sample. 
• The cone rotates at a controlled speed calibrated to produce a defined shear rate at the sample: 10,000 s⁻¹ for BS/ISO or 12,000 s⁻¹ for ASTM. 
• Torque induced on the cone by the sample’s resistance is measured and converted into dynamic viscosity (in poise or centipoise), displayed on the LCD. 

At these shear rates the reading approximates the viscosity a paint or coating experiences under brush or roller application – so lab measurements are directly relevant to production and end-use behavior, unlike static flow-cup or Krebs-unit readings which measure at different shear conditions. 

What happens after you enquire

When you enquire about the TQC Sheen Cone and Plate Viscometer CP1, our TQC Sheen specialists will confirm which shear-rate standard you test to (BS 3900-A7, ISO 2884 or ASTM D4287), the typical viscosity range of your samples (this drives cone kit selection), whether you also need calibration oils for periodic verification, and any customer-specific R&D or QC protocol requirements. Cone kits are quoted separately based on your viscosity range. 

For purchasing teams, we provide the SKU (DV2500), quotation turnaround and technical documentation for internal sign-off. Data Sheet and Manual are already available on the product page. Lead time is confirmed at quotation.

Service, warranty and ongoing support

Every TQC Sheen Cone and Plate Viscometer CP1 is supplied with a 1 year parts and labour warranty as standard – our Industrial Physics group commitment across all brands. Ongoing support focuses on replacement cones (matched to your viscosity range), calibration oil replenishment, and periodic verification against reference viscosities. To arrange service, order replacement cones or discuss calibration verification for your quality management system, contact our support team. 

Beyond the warranty period, the Industrial Physics global service network provides operator training on cone and plate viscometry, sample preparation for repeatable readings, and integrating the DV2500 into a documented R&D or QC workflow across paints, inks and cosmetics manufacture.
