Stormer Viscometer

Measight STM-IV is listed in the stormer / krebs viscometer catalog. Request the current model-specific configuration before placing an order: current measuring specifications, display and data interface need confirmation for the supplied revision. The existing catalog information can support an initial enquiry, but specifications from similarly named instruments should not be treated as a verified replacement for this model’s datasheet.

  • STM-IV is listed in the STM-IV Stormer Viscometer Series.
  • STM-IV is categorized as special-purpose viscometers.

Choosing the STM-IV configuration

When enquiring about STM-IV, provide the full model designation or an existing nameplate photograph and the test method being used. Ask for a current datasheet and photographs of the quoted instrument. The linked alternatives are candidates to compare, not automatic equivalents or evidence that their specifications apply to STM-IV.

What to include in your STM-IV enquiry

For a STM-IV quotation, provide the sample, expected viscosity and unit, test temperature, required method, sample volume and reporting needs. State the destination power supply and quantity. Ask for an itemised spindle, container, temperature-equipment and software configuration, together with the available model-specific documents.
