1. A system, comprising:
a fluid conduit;
a fluid chamber in communication with the fluid conduit to enable the fluid chamber to receive a fluid from the fluid conduit;
a rheology sensor in communication with the fluid chamber to enable the rheology sensor to test a rheological parameter of the fluid while the fluid is in the fluid chamber;
a density sensor positioned along a side loop extending from the fluid chamber to enable the density sensor to test a density of a portion of the fluid extracted from the fluid chamber, wherein the side loop comprises a fluid inlet connected to a first portion of the fluid chamber and a fluid outlet connected to a second portion of the fluid chamber;
an electric temperature controller in communication with the fluid chamber, wherein the fluid chamber is cooled in response to a first control signal from the electric temperature controller, wherein the electric temperature controller includes a thermoelectric material that produces a heated region and a cooling region, and wherein the electric temperature controller includes a pulse width modulator to switch electric current to the thermoelectric material on and off;
a processor; and
memory in communication with the processor, wherein the memory stores instructions that cause the processor to:
receive a user input of a first desired temperature for testing the density of the fluid; and
provide a control signal to operate a pump to cause the portion of the fluid to enter the side loop when the fluid within the fluid chamber is at the first desired temperature to enable the density sensor to test the density of the portion of the fluid at the first desired temperature, wherein the first desired temperature is different from a second desired temperature at which the rheology sensor tests the rheological parameter of the fluid while the fluid is in the fluid chamber.
