Fluke 52 II Dual Probe Digital Thermometer

The Fluke 52 II Dual Probe Digital Thermometer is engineered for demanding applications where accuracy, speed, and versatility are essential. Capable of measuring two separate temperature inputs simultaneously, this thermometer works seamlessly with standard J, K, T, and E-type thermocouples to cover a wide temperature range, reaching up to 900°C (1600°F). Its laboratory-level accuracy of ±(0.05% + 0.3°C) ensures reliable and consistent measurements, making it ideal for tasks such as monitoring motors, insulation, HVAC systems, liquid processes, and electrical components.

The thermometer features a large, backlit dual display that shows T1, T2, T1-T2, and MIN/MAX/AVG values for easier analysis. Its user-friendly front panel simplifies setup and operation, while the sleep mode extends battery life up to 1000 hours. Built to withstand tough environments, the Fluke 52 II comes with a splash- and dust-resistant case and an impact-absorbing holster, ensuring durability and reliability in the field.

Additionally, the electronic offset function compensates for thermocouple errors, ensuring maximum accuracy. The unit also supports the optional Fluke ToolPak accessory, allowing hands-free operation by attaching the thermometer to metal surfaces or pipes. Whether you’re working in laboratories, process control, food safety, or HVAC systems, the Fluke 52 II is designed to deliver precision, versatility, and long-lasting performance.
