All models conform to the most recent ASTM D445, and D2171 specifications using digital indicating PID temperature controller providing bath stability and uniformity of ±0.02°C.

Model 86-20 is by far our most popular model. It has a 305 mm (12 inch) round Pyrex jar is enclosed in a safety cabinet. The 7 test positions located near the front of the viewing window allow easy view of the viscometers. Temperature range is +20° to 150°C. Cabinets are made of anodized aluminum frame and panels. A safety viewing window in front of the bath jar provides an insulating air space and protection against breakage. The cabinet acts as a barrier to room temperature fluctuations from drafts air conditioning vents, opening and closing of doors, etc. Kinematic viscosity is highly temperature dependent, evident by the test method requiring ±0.02°C temperature stability, so the enclosed cabinet provides a key benefit over open jar type baths.  Furthermore this model also uses a high end sophisticated temperature controller used in process control field. The jar is illuminated by a fluorescent back light for easy reading of the meniscus.

Model 86-17D is a traditional open jar type kinematic viscosity bath with a temperature range of +20° to 100°C. A protective clear shield is supplied for improved temperature stability and operator safety versus competitive models. A temperature controller with 0.1°C resolution is supplied.

Model 86-18D is the same as 86-17D but with the use of a temperature controller with 0.01°C resolution and incorporates and additional feature of an RS-232 port for optional PC software.  However, model 86-20 is more popular and recommended.
