The Koehler HKV3000 and HKV4000 series provide reliable, high-temperature kinematic viscosity testing for transparent and opaque liquids, lubricants, and bitumens. Microprocessor PID temperature control ensures precise regulation throughout the bath’s operating range, with dual digital displays for monitoring setpoint and actual temperatures in °C or °F.
The HKV4000 allows users to enter viscometer constants for automatic calculation and display of results in both viscosity units and efflux time, while the HKV3000 features seven digital timers for convenient manual or semi-automated operation. Motorized stirring ensures uniform heat distribution without turbulence, and the built-in cooling coil allows sub-ambient operation when required.
Bath chambers are constructed from clear Pyrex, enclosed in insulated, epoxy-finished steel housing, with seven 2" viscometer ports and glare-free fluorescent illumination for easy viewing. Redundant safety systems protect against over-temperature or low liquid levels, ensuring safe operation at high temperatures. Communication via RS232 allows integration with external software or data acquisition systems.
These baths are fully compliant with ASTM, ISO, IP, DIN, FTM, and NF T standards, making them ideal for quality control, research, and industrial laboratories requiring precise kinematic viscosity measurements under high-temperature conditions.
