Seven sample Water Separability Tester provides full visibility and microprocessor control of all functions for simplified, accurate testing of up to seven samples at a time. Use for specification of new oils and monitoring of in-service petroleum oils and synthetic fluids.
Seven position heating bath – A full visibility bath immerses seven 100mL cylinders at the proper depth per ASTM and ISO specifications. Sample cylinders are held securely in place by stainless steel supports inside the bath. A microprocessor based immersion circulator/heater assembly controls bath fluid temperature with greater than ±1°C accuracy and stability throughout the operating range of 25°C to 150°C. Large LED readouts display setpoint and actual temperatures in celsius or fahrenheit scale at the operator’s option. For most samples, ASTM/ISO sample temperatures of 54°C and 82°C are attained within 10 minutes after placement of the test cylinders into the stabilized bath. Clear Pyrex™ bath has backlighting for excellent visibility when viewing emulsion separations in the test cylinders. Cut-off circuits for low water level and over-temperature conditions provide protection in the event of equipment malfunction. Finished aluminum cover assembly has built-in handles for removal when filling or cleaning the bath.
Microprocessor sample stirrer – To avoid sample movement, the sample stirrer housing pivots to each test position in the bath and locks securely in place at the required position in relation to the 100mL sample cylinder. The digital stirrer offers complete flexibility for test duration and stirring speed at the push of a button. Operating speed and count down time are prominently displayed on a large backlit LCD panel. A wide operating range of 60 – 1800 rpm permits in-house customized testing with ±1rpm accuracy, and the operator may select a stirring time of up to 99.99 minutes. At the end of the selected interval, the stirrer automatically shuts off and alerts the operator with visual signals that the settling period has commenced. For added convenience, all test parameters are stored in memory and repeated in subsequent tests until they are changed by the operator.
