Fluke Calibration 21038T Stack Thermometer Base

Overview

The Fluke Calibration 21038T is the base unit of the 1560 Black Stack modular thermometry system. It provides the display, main processor, power supply, and communication management for up to eight interchangeable thermometry modules, supporting up to 96 sensor inputs. The system can function as a high-accuracy reference thermometer, an automated calibration system, or a high-resolution data acquisition system.

Each base module performs self-diagnostics on power-up and requires no calibration. Thermometer characteristics are defined by the thermometry modules stacked behind it.
