Why control temperature for viscosity measurement? Defecting changes in your sample's properties is valuable information for predicting your product's performance. Temperature control during viscosity measurement helps insure accurate test results. The addition of a bath is a smart investment, and although the Brookfield Model TC-102 Circulating Water Bath is small in size, packs a powerful punch!     The TC-102 Temperature Control Bath is uniquely configured for use with your Brookfield Viscometer or Rheometer and is available with either an enhanced digital controller (TC-102D) or with a programmable controller (TC-102P). How do you choose?
