Stormer Viscometer KU-3, LCD 200 r/min, for Paint Coating and Ink Viscosity | FMFPAX

Product Details

The FMFPAX KU-3 is a Stormer-type (Krebs) viscometer for measuring the viscosity of paints and other coatings in Krebs Units (KU); the product title also names ink. It is controlled by a microcomputer and shows the result of the test sample as a KU value, a cP value and a g value on the LCD display.

The agitating disc rotates in the sample at a constant 200 r/min, and the resistance acting on the disc is converted into a KU value. The instrument is designed in accordance with ASTM D562 and GB/T 9269.

Packing List

• Host (main unit) × 1
• Blade (agitating disc) × 1
• Stainless steel cup × 1
• Cup cushion disk × 2

How to Use

1. Fix the agitating disc in the shaft sleeve with the screw; the screw must bear against the flat face of the disc shaft.
2. Switch on at the back of the machine; after the self-check the display reads 0 for KU, cP and g.
3. Fill the vessel to 10 mm below the rim and place it on the vessel seat.
4. Choose the unit, then press the lift handle down until the mark on the disc shaft is level with the liquid surface; measuring starts automatically.
5. Read KU, cP and g after a few seconds, use the Hold switch to record, then lift the handle to the top limit stop.

Selection Notes

• Choose this instrument when your workflow requires a Stormer-type viscometer for KU viscosity checks on paint and coating samples.
• The user manual states 220 V, 50 Hz input power, while the product title lists 110V/220V. Confirm your voltage requirement with sales@fmfpack.com before ordering.
• Place the instrument on a firm, level table away from strong airflow and magnetic or electric fields, and use a reliably grounded power socket.
• The manual recommends annual inspection by the supplier or calibration by a metrology department.
