Superior accuracy and functionality in an economical benchtop packageb>
The 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 Calibration temperature calibrator, sourcing and measuring a complete range of RTDs, thermocouples, and thermistors. It also measures pressure covering common ranges from 1 inch (6900 Pa) of water up to 10,000 PSI (69 Mpa) using the Fluke Calibration 700 Series or 525A-P 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 0-100V output and 0-100 mA current capabilities — plus its ability to serve as a highly-accurate pressure standard — make it a versatile performer.
A good fit for ATE test applications
With precise calibration-grade instrument control enabled via an IEEE bus, the 525B is a hard working addition to automated test systems in quality and manufacturing test applications requiring capabilities such as voltage and current sourcing, sensor simulation, and temperature monitoring and validation
An optional set of external pressure modules provides pressure measurement capability. The 525B can accept either the Fluke Calibration 700 Series pressure modules or the Fluke Calibration Model 525A-P series pressure modules. These modules plug directly into the calibrators front panel Lemo connector; the 525B firmware auto-detects the type and value of the attached module.
Included with Fluke 525B: Thermocouple and test lead set 1 meter TC wire with male mini-plugs, All ANSI, L and U types; TC shorting plug; 1, 80AK-8001 TC adapter; 1, bead thermocouple type K; 1 meter shielded test lead with double banana plugs (M); 2, 30 A test leads and banana type connectors.
