• HKV4000 model permits entry of viscometer constants for automatic calculation and display in viscosity units or seconds
• Dual digital displays show setpoint and actual bath temperature
• Selectable temperature scale - Fahrenheit or Celsius
• Integrated redundant overtemperature and low liquid level cut-off circuitry
• Conforms to ASTM D445, D2170 and related specifications
High temperature baths with advanced temperature control circuitry and integrated timing features for convenient, accurate glass capillary viscometry determinations. Microprocessor PID circuitry assures precise, reliable temperature control within ASTM specified tolerances throughout the operating range of the bath. Simple push-button controls and dual digital displays permit easy setting and monitoring of bath temperature. Two place calibration offset capability is provided. Baths accommodate seven glass capillary viscometers of various types - see pages 10-13 for complete selection of viscometers and holders. Viewing the viscometers is made easy by glare-free fluorescent illumination inside the bath and a baffle that provides a background for easy viewing. Temperature control uniformity is assured by means of motorized stirrer which provides complete circulation without turbulence. Connection of the built-in cooling coil to tap water or a recirculating water chiller facilitates temperature control at ambient or below ambient temperatures.
