1551A EX, 1552A EX specifications

The Fluke 1552A EX and 1551A EX are specialized temperature calibration tools designed for professionals working in hazardous environments. These portable devices cater to the needs of industries such as petrochemical, pharmaceutical, and food processing, where accuracy and safety are paramount.

One of the standout features of the Fluke 1552A EX is its ability to measure a wide temperature range with exceptional accuracy. The instrument can operate from -200°C to 700°C (-328°F to 1292°F), making it versatile for various applications. It comes equipped with advanced thermocouple capabilities, supporting multiple thermocouple types, including J, K, T, E, N, R, and S. This versatility ensures that users can perform calibrations on different temperature sensors seamlessly.

The 1551A EX, on the other hand, capitalizes on the innovations seen in the 1552A but is particularly designed for lower temperature applications, operating from -200°C to 1200°C (-328°F to 2192°F). It also allows users to interchange between various temperature probes, granting flexibility for different measurement needs. Both models feature a high-resolution display that provides clear and immediate readings, further enhancing user experience.

Another significant technology utilized in both the 1552A EX and the 1551A EX is Fluke’s Calibration Technology. This feature allows for consistent and precise adjustments to be made, ensuring that results remain accurate over time. The instruments are also designed following the latest standards for safety, featuring explosive atmosphere compliance, which allows them to operate safely in environments where flammable gases or vapors may be present.

In terms of usability, both models incorporate a user-friendly interface that simplifies operations, even for those less familiar with calibration procedures. The devices also include rechargeable battery options, extending their portability for use in the field. Additionally, they are housed in durable enclosures, designed to withstand the rigors of industrial environments.

Overall, the Fluke 1552A EX and 1551A EX are top-notch calibration instruments that not only meet the rigorous demands of hazardous work environments but also deliver exceptional performance, accuracy, and safety features that professionals can rely on for their temperature calibration needs.
