SimAir™ Test Cells for ASTM D2983
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Block Bath for sample preconditioning, 10 test positions.
Model BV has two air test chambers. Ample storage is provided inside the cold chambers for pre- cooling the insulated cell carriers.
Far superior viscosity data repeatability is obtained using this procedure as opposed to the air chamber procedure. Procedure C is used when a mechanically refrigerated constant temperature atsm bath is used to cool samples by means of a simulated air cell SimAir 3 Cell in preparation for viscosity measurement. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of astj standard. Model BV is a compact, bench top unit with 6 sample capacity with digital sample temperature display.
Caution should be taken when handling mercury and mercury containing products. Model BV is a smaller, floor space saving, compact unit, with 12 sample capacity. No viewing window, but with digital sample temperature display. Recommended accessories for BV40 or BV This test method is used in a number of specifications.
Lawler | ASTM D Low Temp Brookfield Viscosity Baths
The key factor in this improved precision is the superior temperature control of the sample as its viscosity is being measured. The bath is supplied with an integral leveling viscometer support rod. Model BV is a smaller, floor space saving, compact unit, with 12 sample capacity. The illuminated jar allows full visibility of the test samples to facilitate the proper position of the spindle bead immersion level.
This allows operating baths at two independent temperatures with independent start, stop, and duration times. The spindle is connected while the sample is still in the liquid bath. Procedure B is used when a mechanically refrigerated programmable liquid bath is used to cool samples in preparation for viscosity measurement.
A video chart recorder option -V to track possible temperature upsets, and a digital sample temperature display option -D are available for Model BV Model BV d29883 a compact, bench top unit with 6 sample capacity with digital sample temperature display.
D2893 digital, indicating controller with resolution of 0. Low temperature viscosity values obtained by either interpolation or extrapolation of oils may be subject to errors caused by gelation and other forms of non-Newtonian response to spindle speed and torque.
Sample temperature digital display for Model BV70 only; included with others. Specifications subject to change without notice.
SimAir™ Test Cells for ASTM D
Recommended are at least 2 reference fluids for each desired test temp. Mercury, or its vapor, may be hazardous to health and corrosive to materials. The use of programmable liquid baths for ASTM D has been allowed since the first development of the test if the cooling profile meets the specifications of Annex A2 of the method.
At least two reference fluids are recommended for each desired test temperature per viscosity. This allows the measurement of viscosity without removing the sample from the temperature controlled environment.

Each chamber has a turn table with 6 sample capacity each.
Each model is equipped with turntable rotating at 4 RPM. Kits do not include the Brookfield Viscometer, which can be purchased separately.
