Constant temperature bath with advanced temperature control circuitry for convenient, accurate glass capillary viscometry determinations.


The kinematic viscosity of the base oil is determined utilizing ASTM D445. First, a test bath must be maintained within ±0.02°C for temperatures between 15°C and 100°C or within ±0.05°C otherwise. Furthermore, thermometers must be in the upright position and in the same position as when calibrated. A clean, dry, calibrated viscometer must be used under the condition that the flow time of the manual viscometers does not exceed 200 seconds. Once the test temperature is below the dew point, the viscometer must be filled then inserted into the test bath.

It is then possible to observe and record the flow times for viscosity calculation.


Microprocessor PID circuitry assures precise, reliable temperature control within ASTM specified stability and uniformity throughout the operating range of the bath.

Simple push-button controls and dual digital displays permit easy setting and monitoring of bath temperature. Baths accommodate seven glass capillary viscometers of various types. Viewing the viscometers is made easy by LED illumination inside the bath and a baffle that provides a background for easy viewing.

Temperature control uniformity is assured by means of an integrated stirrer and baffling system for uniform bath temperature distribution. Connection of the built-in cooling coil to tap water or a recirculating water chiller facilitates temperature control at ambient or below ambient temperatures.
