The Rheomat RM180 viscometer is a rotational viscometer with concentric measuring systems. It is a portable, easy to use viscometer, used primarily for quality control and product development. It can be used manually using simple push buttons on the keypad or using a personal computer and optional software. The Rheomat can use concentric cylinders, TV spindles and ISO 2555 measuring systems. It uses a rechargeable battery for portability or in the laboratory it has it's own stand and power supply. The data is displayed on the Rheomats' Liquid Crystal Display and can be downloaded to printer or personal computer. Typical applications for the Rheomat include cosmetics, food and coatings. An RS232 serialport is available for direct connection to your PC. A Centronics parallel port provides a direct link to a printer. Single point measurements can be made in the Manual mode where you can enter the shear rate. Viscosity is displayed along with other parameters including temperature, torque, measuring system and stress. Pressing the printer key will print the values directly to a printer. In the automatic mode you can choose between programs recording 8 measuring points at a time, going up in shear rate and then down. This allows for a flow curve with 15 data points obtained automatically. Viscosity determination can be made using measuring systems including concentric cylinders according to DIN 53019 for determination of apparent viscosity. TV spindle geometry is used for UD measurement values. Kinematic viscosity determination can be measured by inputting the sample density.
