Caution should be taken when handling mercury and mercury containing products. This allows operating baths at two independent temperatures with independent start, stop, and duration times. A Windows based PC is required not supplied. The turntable holds 10 test samples. Model BV is a compact, bench top unit with 6 sample capacity with digital sample temperature display.

Floor Model Viewing Window. Specifications subject to change without notice. It is d293 for those laboratories with a very light sample load and limited space and budget. After the 16 hours conditioning time, the turntable is manually rotated until the proper test cell is under the viscometer.

Measurement of the viscometric properties of these oils and fluids at low temperatures is often used to specify their acceptance for service. Work Item s – proposed revisions of this standard. The twin air chambers are independently temperature controlled. This allows the measurement of viscosity without removing the sample from the temperature controlled environment. Model BV has two air test chambers.

Block Bath for sample preconditioning, 20 test positions. Historical Version s – view previous versions of standard Work Item s – proposed revisions of this standard Translated Version s: Each chamber has a turn table with 6 sample capacity each.

This test method is used in a number of specifications. No viewing window, but with digital sample temperature display.

Procedure B is used when a mechanically refrigerated programmable liquid bath is zstm to cool samples in preparation for viscosity measurement. Recommended are at least 2 reference fluids for each d29833 test temp.

The spindle is connected while the sample is still in the liquid bath. A video chart recorder option -V to track possible temperature upsets, and a digital sample temperature display option -D are available for Model BV Each model is equipped with turntable rotating at 4 RPM.

SimAir™ Test Cells for ASTM D2983

The Lawler liquid baths are programmed such that the sample cooling rate equals the cooling rate experienced by a sample when immersed in the constant low temperature asm chamber. Recommended accessories for BV Link to Active This link will always route to the current Active version of the standard.

Far superior viscosity data repeatability is obtained using this procedure as opposed to the air chamber procedure. The two chambers allow simultaneous conditioning of samples at the same asm different temperatures for quicker data collection then with only one apparatus.

Home Products Contacts Search. The success of the ATF correlation and the development of this test method has over time been applied to other fluids and lubricants such as gear oils, hydraulic fluids, and so forth.
