Product details

The viscosity of liquids, whether Newtonian or non Newtonian, is temperature dependent and typically decreases with increasing temperature. In order to accurately test the viscosity of the sample, it is first necessary to consider precise temperature control of the sample. The viscosity of most samples is very sensitive to temperature changes, and the precision of temperature control is required to reach ± 0.1 ℃.

Our company specializes in producing various viscometers, as well as matching viscometer specific constant temperature water baths (oil baths) and viscometer specific low-temperature constant temperature water baths. The CH N series constant temperature water bath (oil bath) adopts the latest high-performance single-chip microcomputer control, self-tuning PID regulation, imported platinum resistance temperature measurement, high temperature control accuracy, and small fluctuation; The CH series adopts a large backlit LCD display screen, with clear and concise parameters, beautiful and fashionable; Equipped with disconnect protection and liquid level protection devices, it can effectively prevent various faults caused by instrument loss of control and heating tube burnout. The instrument works stably and reliably, with convenient and safe operation.

The HCH series adopts dual row luminous digital display, with temperature measurement and set temperature displayed separately, making it easy to use.

The unique circular opening can hold a 200ml beaker for direct viscosity measurement. The external circulation function can also lead controlled constant temperature liquid to an external constant temperature cup, meeting different testing requirements.
