• Conforming to ASTM D445 and related specifications
• Choice of -300°C (-220°F) or -600°C (-760°F) operating range
• Available digital temperature display

Mechanically refrigerated constant temperature baths for low temperature kinematic viscosity determinations. Temperature uniformity is maintained within +0.030°C (±0.050°F) throughout the operating range. Baths accommodate four glass capillary viscometers - specify round or rectangular ports to match holder type. Fluorescent interior illumination and an evacuated clear Dewar flask assure excellent visibility. Air- cooled, hermetic compressors and electronic solid state temperature control provide efficient operation with long term reliability. Polished stainless steel cabinets have safety viewing shield and levelling legs.

Operating range to -1000°F (-730°C)

For low temperature kinematic viscosity determinations on liquid petroleum products. Fully insulated bath uses cooling mixtures to attain temperatures as low as -1000°F (-730°C). Electronic solid state controller maintains temperature uniformity of +0.050F (±0.030°C) throughout the operating range.

Stainless steel dry ice containers suspend from the top plate into the cooling chamber for standard cooling, and two brass containers suspend directly into the cooling medium for rapid cool down if needed. Finished steel cabinet has a full 3" (7.6 cm) of cork insulation surrounding the interior chamber.

Accommodates three glass capillary viscometers in a Pyrex^TM jar.

Large 11-1/4" x 6-1/4" (28.6 x 15.9 cm) viewing window has seven hermetically sealed panes to prevent frosting. An externally mounted variable intensity lamp illuminatesthe bath interior through an insulated opaque rear window. Stainless steel bath stirrer is driven by a 1/20 hp 1750 RPM explosion-proof motor.

Sturdy 1/2" (1.3 cm) composition top plate supports stirrer assembly, viscometer holders, coolant cylinders, thermistor probe and the thermometer, and is easily removed for access to the interior.

Conforms to the specifications of: ASTM D445, D2532, IP 71, ISO 3104, DIN 51550, FTM 791-305.
