Ideal for the study of flame temperatures. The thermocouple sensor measures the temperature difference between two points. Range is –200°C to 1400 °C with precision of ±2 °C. Demonstrate the various temperatures of a flame or follow an exothermic reaction in a classroom. Has a built-in ice-point compensation chip so there is no need to place a reference wire in a ice-water bath. Analog sensor. Use with LabQuest Mini or LabQuest 2 interfaces.
