Lawler | ASTM D Low Temp Brookfield Viscosity Baths

Block Bath for sample preconditioning, 20 test positions. Block Bath for sample preconditioning, 10 test positions. Procedure B is used when a mechanically refrigerated programmable liquid bath is used to cool samples in preparation for viscosity measurement. Mercury, or its vapor, may be hazardous to health and corrosive to materials. It is designed for those laboratories with a very light sample load and limited space and budget. Each chamber has a turn table with 6 sample capacity each.

A Windows based PC is required not supplied. Procedure C is used when a mechanically 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.

SimAir™ Test Cells for ASTM D2983

Paperless videographic temperature recorder with flash memory card. At least two reference fluids are recommended for each desired test temperature per viscosity.

Model BV has an 28 cm 11 inch square, multipane, insulated window with fluorescent light for observation of the interior, with 28 sample capacity. Procedure A d29883 used when only an air bath is 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. Historical Version v2983 – view previous versions of standard.

This test method is used in a number of specifications. Historical Version s – view previous versions of standard Work Item s – proposed revisions of this standard Translated Version s: Far superior viscosity data repeatability is obtained using this procedure as opposed to the air chamber procedure. It is designed for those laboratories with a very light sample load and limited space and budget. Each model is equipped with turntable rotating at 4 RPM. The illuminated jar allows full visibility of the test samples to facilitate the proper position of the spindle bead immersion level.

Model BV has two air test chambers. 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.

Floor Model Viewing Window. 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. Specifications subject to change without notice. Work Item s – proposed revisions of this standard. No viewing window, but with digital sample temperature display. Ample storage is provided inside the cold chambers for pre- cooling the insulated cell carriers. No other units of measurement are included in this standard.

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

The spindle is connected while the sample is still in the liquid bath. A digital, indicating controller with resolution of 0. Recommended accessories for BV The twin air chambers are independently temperature controlled.

Recommended are at least 2 reference fluids for each desired test temp. No viewing window, but with digital sample temperature d29983. This allows the measurement of viscosity without removing the sample from the temperature controlled environment.
