Here are some key features and functionalities of the Fluke 724:

1. Dual Inputs and Display: It can simultaneously read two temperature inputs and can show T1, T2, or the differential between the two.

2. Multiple Temperature Measurements: The Fluke 724 can measure and source RTDs (resistance temperature detectors), thermocouples, ohms, and voltage, covering a broad range of temperature calibration applications.

3. Easy-to-use Interface: The device features a simple keypad and a clear display, which allows users to easily navigate through its functions and features.

4. Temperature Source and Measurement: The device can both measure temperature from a source and simulate a temperature source for testing and calibrating other devices.

5. Automated Functions: For increased efficiency, the Fluke 724 can automatically step through different temperature values in a sequence, which is helpful when calibrating temperature devices that have multiple setpoints.

6. Built-in Conversion Tables: It has built-in temperature conversion tables for various thermocouple types, which can greatly simplify the process of calibration.

7. Durable and Reliable: Like most Fluke devices, the 724 is built to withstand tough working conditions, and its rugged design ensures it can handle the demands of fieldwork.

8. Additional Measurement Capabilities: Apart from temperature, the Fluke 724 can also measure pressure using Fluke pressure modules, making it a versatile tool for calibration tasks.

In summary, the Fluke 724 Temperature Calibrator is a versatile and comprehensive tool for professionals who need to calibrate temperature sensors and devices. It combines the functions of several instruments into one, simplifying the process of temperature calibration and verification.
