Conforming to ASTM D445, the TVB445 is perfectly adapted for viscosity measurement, as well as for thermometer calibration, crystal growing, density and reaction rate measurement, and much more.



Manual Viscometer Bath

Test Methods
ASTM D445, ASTM D446, DIN 51562, IP 71, ISO 3104, ISO 3105, GOST 33

The ISL Manual Viscometer Bath TVB445 is designed to perform a variety of accurate temperature controls required for general laboratory use or as a constant temperature bath. Complying to ASTM D445 standards, the TVB445 meets the requirement of viscosity measurement for highly precise temperature control but also can be applied to applications that require visual monitoring (crystal growing, density and reaction rate measurement, etc.).

The TVB445 is easy to operate and accommodates up to seven standard capillary tubes (with an optional eighth). Its compact design features a durable, stainless steel housing and inner bath. A built-in cooling coil makes it ideal for sub-ambient applications, and bath windows and optional lighting provide visual monitoring capabilities.
