One of Fluke best-selling products is the Tweener thermometer, and there’s a reason. No other company, not one, has a thermometer that comes close to the performance and features of the Tweener. The 1502A Tweener features accuracy up to ± 0.006°C.

Each Tweener is programmable to match a probe’s constants for maximum linearity and accuracy. All probe constants and coefficients are programmed through simple, front-panel keystrokes. Temperature is displayed in °C, °F, K, or resistance in ohms.

The 1502A is calibrated digitally using the front-panel buttons. You never have to open the box to calibrate it. This calibration protocol further reduces the cost of the 1502A. It goes where you go and works the way you want it to.
