Automatic temperature compensation probes with electrochemistry meters use thermal detection to measure the temperature of a sample. Probes adapt the test results based on the effects of temperature. pH may be incorporated into testing using a separate probe. Probes come in a variety of materials including epoxy, glass, and stainless steel. Thermo Scientific™ Orion™ Stainless-Steel Automatic Temperature Compensation (ATC) Probes correct pH measurements for variation in electrode slope automatically.
