Gdj-1c ASTM D4402 Digital Brookfield Rotation Viscometer

GDJ-1C Brookfield Rotational Viscometer

I. Introduction

is designed and made as per T0625 in the Industry Standard JTJ052 , and ASTM D4402. is suitable to determine apparent viscosity of highway asphalt at a temperature from 45 °C to 200 °C as per Brookfield Viscometer Rotation Methods. The can also be used to determine construction temperature for bituminous mixture as per viscosity-temperature curve. The can also be used to determine viscosity of hot melt adhesive, oil grease, paraffin and high polymer. It can be widely used in cosmetics, food, pharmaceutical, dopes, chemical, and other industries.II.Technical Parameters Measurement range25mPa•s~1x10000000mPa•s (If purchase the No.30 spindle, its measurement range canbe extended to 2x10000000mPa•s)Spindlesfour spindles of No.21, 27, 28 and 29 (No.30 spindle is optional)Spindle speed0.1~100 RPM continuously adjustedMeasurement error± 2% (F•S) (± 3% (F•S) for No.30 spindle)Temperature controlling range25°C~200°CTemperature controlling accuracy±0.1°CCubage of sample chamber20 mlPower supplyAC 220V±10%, 50 HzAmbient temperature5°C~35°C (the ambient temperature should be about 5 °C lower than controlling temperature of heater)Relative humiditynot more than 80%
