Programmable Touch-screen Viscometers with Temperature Control combine viscosity measurement and temperature control in one machine. It break the current way to measure viscosity which need use thermostatic bath, viscometer and small amount sample adapter separately.
Measuring sample’s viscosity change under different conditions is very useful for estimating its rheological behavior, while controlling sample temperature precisely is helpful for getting an accurate and comparable test result.The most obvious advantage of this machine is controlling sample temperature precisely during the whole test. Its temperature controlling system consists of semiconductor and a built-in automatic optimization progamme of temperature control. The temperature controlling precision can reach ±0.1℃. Operator can control sample temperature not only by machine, but also by optional software, has a excellent flexible operation.
Features
◆ Consists of 7 inch wide touch screen viscometer, small amount sample adapter（SSR）, cylindrical sample sleeve and SC4 rotor, tempeater controller.
◆ BGD 157 can display shear rate and shear stress, can fulfil a precise measurement under a certain shear rate.
◆ Only need 2ml～16ml sample，the cylindrical structure of SC4 rotor can offer a precise viscosity measurement
◆ Electrical lifting and presice location, SSR is easy assembly and disassembly, convenient to clean.
◆ SSR fits temperature controller closely, can ensure a precise constant temperature to sample.
◆ Small amount sample, rotor stir action can minimize the non-uniformity of sample temperature, shorten greatly sample hydrothermal time.
The other features of Viscometer are the same as Programmable Touch-screen Viscometer.
