How fast does the viscometer respond to changes in viscosity or temperature?
The viscosity measurement response time is effectively two seconds. Measurements are made 5 times per second; however, the analog outputs are refreshed every two seconds. If data is being read on the serial port, the fastest “Logging” [output] refresh time is 10 seconds. Of course, to achieve fast measurement response it is important to have robust flow. Temperature measurement has a thermal characteristic time of about 30 seconds, so a step change in temperature will be accurately sensed within two minutes. For additional details see technical note TN4355, “Thermal Response Time”.
