Fungilab – VISCOLEAD SERIES ONE

The VISCOLEAD ONE is a digital viscometer for laboratory use, designed for precise viscosity measurement and quality control with programmable features and user calibration.

  • Wide Viscosity Range – Covers from 1 cP up to 106,000,000 cP, with low, medium, and high viscosity models.
  • High Accuracy & Repeatability±1% full-scale precision and 0.2% repeatability.
  • Programmable & Automated Testing – Includes AUTO-TEST, AUTO-RANGE, and 10 language options.
  • Flexible Accessories – Supports low viscosity adapters, small sample adapters, helix drive, and temperature control units.

Description

The Fungilab VISCOLEAD Series ONE is a versatile and precise rotational viscometer designed for dynamic viscosity measurements in laboratory and industrial settings. It provides real-time viscosity readings (cP/mPa·s) along with selected speed, spindle identification, and sampling temperature, while also offering a unit converter from SI to CGS. Key features include AUTO-TEST with visual and resonant alarms, AUTO-RANGE functionality, and user-enabled viscosity calibration, all accessible through an intuitive interface supporting 10 language options. The device is compatible with a range of AISI 316 stainless steel spindles, fulfilling international standards including BS, ISO, and ASTM.

Available in low, medium, and high viscosity models, the VISCOLEAD ONE can measure from 1 cP up to 106,000,000 cP, with optional fast spindle switching (PPR) for increased efficiency. The series supports a variety of accessories such as small sample adapters, low viscosity adapters, helix drive units, and temperature control units up to 300°C, making it suitable for both standard liquid testing and specialized applications with small or non-flowing samples. This combination of precision, flexibility, and ease of use makes it ideal for research, quality control, and production monitoring.

Features

  •  Data display: speed: rpm, rotor: SP, viscosity: cP (mPa.S), percentage of full scale: %
  •  Viscosity measurement: dynamic viscosity
  •  Unit conversion: Sl unit system converted to CGS units
  • Self-test function: viscometer self-test function, sound and light alarm reminder
  • Range function: After selecting a combination of rotor and speed, the maximum range under this combination will be automatically calculated.
  • User-defined viscosity calibration
  •  10 languages â â to choose from
