Model BV has an 28 cm 11 inch square, d9283, insulated window with fluorescent light for observation of the interior, with 28 sample capacity. Windows based PC proprietary software is capable of controlling two baths simultaneously.

Model BV has an 28 cm 11 inch square, multipane, insulated window with fluorescent light for observation of the interior, with 28 sample capacity.

Recommended accessories for BV40 or BV Home Products Contacts Search. Model BV is a compact, bench top unit with 6 sample capacity with digital sample temperature display. Historical Version s – view previous versions of standard Work Item s – proposed revisions of this standard Translated Version s: Kits do not include the Brookfield Viscometer, which can be purchased separately.

Sample temperature digital display for Model BV70 only; included with others. Mercury, or its vapor, may be hazardous to health and corrosive to materials.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

The illuminated jar allows full visibility of the test samples to facilitate the proper position of the spindle r2983 immersion level.

SimAir™ Test Cells for ASTM D

Model BV is a smaller, floor space saving, x2983 unit, with 12 sample capacity. This test method is used in a number of specifications. 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 air chamber.

At least two reference fluids are recommended for each desired test temperature per e2983. Floor Model Viewing Window. This allows operating baths at two independent temperatures with independent start, stop, and duration times. No viewing window, but with digital sample temperature display. Ample storage is provided inside the cold chambers for pre- cooling the insulated cell carriers.

SimAir™ Test Cells for ASTM D2983

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 astk Annex A2 of the method.

A video chart recorder option -V to track possible temperature upsets, and a digital sample temperature display option -D are available for Model BV This allows the measurement of viscosity without removing the sample from the temperature controlled environment. S2983 B is used when a mechanically refrigerated programmable liquid bath s2983 used to cool samples in preparation for viscosity measurement. The key factor in this improved precision is the superior temperature control of the sample as its viscosity is being measured.

The two chambers allow simultaneous conditioning of samples at the same or different temperatures for quicker data collection then with only one apparatus. Caution should be taken when handling mercury and mercury containing products. Work Item s – proposed revisions of qstm standard. Specifications subject to change without notice.

Brookfield digital viscometer and DV Loader configuration software. It is designed for those laboratories with a very light sample load and limited space and budget. A Windows based PC is required not supplied.

Lawler | ASTM D Low Temp Brookfield Viscosity Baths

Ample storage is provided inside the cold chambers for pre- cooling the insulated cell carriers. The d2938 is connected while the sample is still in the liquid bath. Measurement of the viscometric properties of these oils and fluids at ast temperatures is often used to specify their acceptance for service.

Block Bath for sample preconditioning, 10 test positions. The bath is an unsilvered Dewar jar holding about 3 liters of bath medium. Procedure A is used when only an air bath is used to cool samples in preparation for viscosity measurement. The twin air chambers are independently temperature controlled. The bath is supplied with an integral leveling viscometer support rod. Paperless videographic temperature recorder with flash memory card. Model BV has two air test chambers. No other units of measurement are included in this standard.

Model BV is a smaller, floor space saving, compact unit, with 12 sample capacity.

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 astmm to spindle speed and torque. Each model is equipped with turntable rotating at 4 RPM.

Model BV is a compact, bench top unit with 6 sample capacity with digital sample temperature display. 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. After the 16 hours conditioning time, the turntable is manually rotated until the proper test cell is under the viscometer.

A digital, indicating controller with resolution of 0. It is designed for those laboratories with a very light sample load and limited space and budget. Procedure C is used when a sstm refrigerated constant temperature liquid bath is used to cool samples by means of a simulated air cell SimAir 3 Cell in preparation for viscosity measurement.
