	CONE &Plate Viscometer The viscosity of coatings, such as paint, show typical changes when applied with brush, roller or spray gun etc. under high shear rates. For this reason, it is essential that the flow behaviour of such non-newtonian products is tested under stringent conditions, in order to achieve optimal formulation and process monitoring. Standardised test methods recommend a shear rate of 10,000 s.' (BS) or 12,000 s.' (ASTM) as satisfactory test figures. This new Cone & Plate viscometer is specially designed for this purpose. A highly accurate wear resistant cone rotating at high speed on a temperature controlled plate simulates the expected "real world" application shear. The combination of the instrument's 2 standard speeds and the choice of 5 viscosity ranges allow precise testing of a wide range of products in compliance with National test methodologies.

	Rotothinner This easy to use viscometer allows the operator to continuously monitor the viscosity of the test sampie, whilst simultaneously adding a solvent or thinner. A sam pie taken from large production batch can be quickly measured in a 250 ml tin and the related thinning ratio scaled for instant process adjustment if required. The Rotothinner's robust construction enables it to operate either in a production environment or in the laboratory. A selection of 3 versions equipped with ball or disc shaped rotors cover the various test ranges. Features Continuous reading in Poise Simple to install spindie into quick release chuck, easy to clean Possibility of multi-point calibration by user withoptional key Memory for 9 readings, RS232 serial interface to printer Standard package: Viscometer, 1 spindie, 250 ml tin can, printer cable. Performance 3 models & measuring ranges: 0-15, 0-65,1-340 Poise o Spindie speed: 562 rpm, :t 1% Resolution: 0.1 P; 1 P for 340 P model Accuracy: :t-2%; repeatability: :t1 % of full scale Operating temperature: +15° to +35°C 90-240V AC - 50/60 Hz
						Gel Strength Tester 8ased on the Rotothinner design, this instrument is specially suited to assess the yield strength and consistency of thick paints and other materials such as gels and putties etc. A 250 ml can containing the sam pie is magnetically fastened onto a turntable, wh ich is loaded with a calibrated spring displaying an engraved scale of 0-450 gm/cm. When immersed into the sampie, the flat 4 x 2 cm paddle spindie rotates automatically at 2 rpm, and drives the whole can & turntable. After a peak reading followed by a short time of stabilisation, a steady torque value is indicated on the scale. Other paddle sizes are available on request. Features Electronic constant speed control over the full range Paddle spindie simple to install with quick release chuck,easy to clean Safety height sensor preventing the rotor from rotatingabove the can Sturdy construction for use either in lab or production line Standard package: Viscometer, paddle spindie,250 ml / 085 mm can. 220-240V - 50 Hz

	Krebs Viscometer - Digital Based on the popular traditional KREBS method, using a weight-driven rotating paddle to sense the paint viscosity at a constant 200 rpm, this modern digital instrument provides automated motor operation, without weights & pulley, allowing accurate direct reading in KU (Krebs units), mPa.s (cP) or 9 (gram). The conversion between these units is automatically calculated by the microprocessor and displayed on request. Sturdy construction allows for use either in a production environment or in the laboratory.
