The Fluke 525B Temperature/Pressure Calibrator gives you a workhorse combination of high accuracy and broad functionality for temperature and pressure instrument calibration. Compact and economical, the 525B has an interface for automated calibration, providing wide workload coverage in instrument shops and calibration labs, as well as in ATE applications.

The 525B is the most accurate Fluke temperature calibrator, sourcing and measuring a complete range of RTDs, thermocouples, and the YSI 400 thermistor. It also measures pressure covering common ranges from 1 inch (6900 Pa) of water up to 10,000 PSI (69 MPa), using the Fluke 700 Series and 525A-P Series Pressure Modules. Plus, the DC voltage and current specifications of the 525B enable you to calibrate other process calibrators and a wide variety of other instruments with accuracy that rivals any calibrator in its price range.

At Home in the Cal Lab

The 525B is a compact bench instrument well-suited for traditional calibration laboratories with a large temperature workload. Its 0 to 100V output and 0 to 100mA current capabilities, plus its ability to serve as a highly accurate pressure standard, make it a versatile performer.

Filling the Gap in the Instrument Shop

In process plant environments, instrument shop technicians responsible for maintaining the equipment pool need to calibrate and repair a wide range of instruments, transmitters, field calibrators, P/l converters, transducers, and temperature probes. With its ability to simulate almost any temperature sensor, precise pressure monitoring capability, and high DC voltage and current accuracy, the 525B fills in the gap between lower accuracy handheld field calibrators and more expensive, high-end multifunction calibrators.

A Good Fit for ATE Test Applications

With precise calibration-grade instrument control, enabled via an IEEE bus, the 525B is a hardworking addition to automated test systems in quality and manufacturing test applications that require capabilities such as: voltage and current sourcing, sensor simulation, and temperature monitoring and validation.

Powerful Functionality that is Easy to Use

From start to finish, the 525B is designed for ease of operation. The intuitive front panel design features large keypads and a display that help reduce training time. This makes the 525B comfortable to use even for long periods of time. Plus, you can store frequently used constants for a variety of probes in its memory for faster setup on the job.

MET/CAL Plus Automates 525B Calibration and Documentation Management

You can use the 525B with MET/CAL Plus calibration software (V.6.11 or later) to meet the stringent documentation and reporting requirements imposed by quality standards (ex. ISO 9000). MET/CAL Plus is a powerful software environment for creating, editing, testing, and documenting calibration procedures, and for performing automated calibrations.

At the core of MET/CAL Plus is MET/TRACK software, a database management system for test and measurement assets created specifically to manage equipment. It enables you to track the information you need to maintain quality calibrations. And it supports the traceability and record-keeping requirements of modern quality and accreditation standards.

MET/TRACK provides you with a variety of standard report formats prepared with Crystal Reports Professional, which is included with MET/CAL Plus. These report formats cover a wide range of information to help you meet many of your documentation requirements (including those for ISO 9000, and similar quality standards). They report on forward and reverse traceability, allowing you to easily document traceability from any asset to the calibrated equipment. It even includes measurement uncertainty reporting to meet the requirements of ISO/IEC 17025.

Pressure Modules

An optional set of external pressure modules provides pressure measurement capability. The 525B can accept either the Fluke 700 Series or the 525A-P pressure modules. Both module types plug directly into the calibrator's front panel Lemo connector; the 525B firmware auto-detects the type and value of the attached module.

World-Class Temperature and Pressure Calibration Solutions

In addition to the 525B Temperature/Pressure Calibrator, Fluke offers a broad range of solutions in temperature and humidity calibration, as well as pressure and flow calibration.

Fluke makes everything you need for calibrating temperature sensors, including SPRTs, PRTs, thermistors, and thermocouples. The constant temperature baths and dry-block calibrators offer unmatched stability, and the primary temperature standards are used in national metrology institutes around the world. More than 30 national measurement institutes rely on Fluke pressure standards to establish their pressure references. Fluke pressure standards, transfer standards, pressure controller/calibrators and monitors are recognized for their advanced features and the realistic specifications that are the hallmark of a true metrology company.
