HKV4000 High Temperature Kinematic Viscosity Baths with Integrated Digital Timing

Kinematic viscosity plays a critical role in petroleum product design and selection. Accordingly, calibrated capillary viscometers measure gravity- or vacuum-driven flow at tightly controlled temperatures.

Features and Benefits

• First, the microprocessor controls temperature from ambient to 232 °C.
• With an external chiller, it also reaches temperatures down to –20 °C.
• Additionally, integrated digital timing simplifies efflux time measurement.
• The HKV4000 accepts viscometer constants and then automatically calculates viscosity or efflux time.
• Meanwhile, dual digital displays show both setpoint and actual bath temperatures.
• Users may also select either Fahrenheit or Celsius scales.
• For safety, integrated circuits provide redundant over-temperature and low-liquid protection.
• Furthermore, the baths comply with ASTM D445, D2170, and related standards.

Bath Description

• These constant-temperature baths deliver precise glass capillary viscometry with integrated timing and advanced control.
• Specifically, microprocessor PID control maintains temperature within ASTM tolerances across the full range.
• Push-button controls and dual displays, therefore, enable straightforward setting and monitoring.
• In addition, two-place calibration offsets allow precise adjustments.
• Each bath accommodates up to seven glass capillary viscometers.
• Moreover, fluorescent lighting and an internal baffle ensure clear, glare-free viewing.
• A motorised stirrer maintains uniform temperature without creating turbulence.
• For sub-ambient operation, built-in cooling coils connect to tap water or chillers.
• Optionally, users may add communications, ramp-to-set, and advanced features.

Integrated Timing Features

• After timer completion, the HKV4000 automatically calculates efflux time and viscosity.

Bath Construction and Safety Features

• A clear Pyrex vessel sits within a durable polyester-epoxy steel housing.
• The stainless steel top includes seven 51 mm viscometer ports for convenient cleaning.
• Additionally, a front viewing window allows safe, distortion-free observation.
• If overheating or probe failure occurs, the microprocessor immediately shuts off the heaters.
• Furthermore, a redundant controller with a separate probe provides independent over-temperature protection.
• An integrated low-liquid sensor also prevents operation at insufficient liquid levels.
• Importantly, safety circuits latch faults until users correct the condition.
• Adjustable levelling feet therefore stabilise the bath during operation.
• A sliding electronics tray also provides convenient service access.
• Finally, the bath includes a thermometer holder and seven handled port covers.
