Calibrated Paint Testing Outfit
• With paddle-type rotor, for determining the viscosity (or consistency) of paints
• In accordance with ASTM Standards D 562, D 816, D 856, D 1084, D 1131, D 1337 and D 1338, Federal Test Standard 141A methods 3011.1, 3012, 3018, 3019, 3022 and 4281 and Federal Specifications TT-P-141b, method 428.1
• Calibrated by the standard method of the Krebs Pigment and Color Corporation to give readings that will duplicate those obtained with other similarly standardized instruments
• A standard one-pint can is used; slotted weights are provided in place of weight box
Paddle rotor, 9731D35, replaces a former fork-type to permit more reproducible readings. Results comparable with those using the fork-type rotor are possible in paints of little or no false body. See R.H. Sawyer, “Development of a Consistency Test,” A.S.T.M. Bulletin No. 102, p. 18; J.A. Geddes and D.H. Dawson, “Calculation of Viscosity from Stormer Viscometer Data,”Industrial and Engineering Chemistry, Ind. Ed., Vol. 34, No. 2, p. 163; and C.F. Jackson and W.H. Madison, “A Method for the Standardization of Krebs Modified Stormer Viscometers,” A.S.T.M. Bulletin No. 161, p. 36.
Includes 2367D11 Test Can; plate to hold can; 9731D35 Paddle-Type Rotor; 9310M74 Thermometer; 9731G45 Weight Set totaling 1160 grams; 9731F10 Plastic Dust Cover; and directions for use containing conversion chart for obtaining result in Krebs Units and standardization graph.
Paint Testing Outfit With Stroboscopic Attachment
• Same as 9730G45, but supplied with 9731F65 Stroboscopic Attachment
• Stroboscope synchronizes visually at required rotational speed of 200 rpm, eliminating time-consuming trial and error in determining the timing and dial reading and making calculation and interpolations unnecessary
Includes all components specified for 9730G45. Extensions for the three vertical support rods, to provide clearance for use of one-quart paint can, are available on special order. Stroboscopic attachment operates on 120 V, 60 Hz.
