Great performance in portable instruments
• Lightweight and very portable
• Accuracy to ±0.25 °C
• RS-232 interface
• Easy to recalibrate

If you’ve been using a dry well calibrator or dry block calibrator for field work, you know there’s a lot more to them than temperature range and stability. Size, weight, speed, convenience, and software are also significant.

A field dry well needs to be portable, flexible, and suitable for high-volume calibrations or certifications. If it's not, you’ll soon forget about the great stuff the sales rep told you and realize what you’ve really bought.

At Fluke Calibration, we use dry well calibrators every day in our manufacturing and calibration work, and we know what makes a dry well easy and productive to use—which is exactly how users describe our series of field dry wells. These dry wells work for you instead of the other way around.

Precision laser alignment made easy
The rugged Fluke 831 has an intuitive guided user interface that enables quick and complete shaft alignment without advanced training or complicated programs. And while it’s easy to use, laser alignment with the Fluke 831 is powerful enough for the skilled technician. You can cover more of your machines with all the functionality needed on the plant floor, from thermal growth to user defined tolerances and more.

Reduce costs by avoiding downtime
Misalignment causes at least half of all damage to rotating machinery, studies show. Instead of fixing the problem, teams often just treat the symptoms of misalignment and replace bearings, couplings, and seals because they think alignment takes too long.
Contrary to expectations, laser alignment can be fast and easy. So, every machine that is repaired and overhauled should be aligned – not just a few. Teams that embrace laser alignment can save thousands of dollars per year by avoiding downtime and energy waste and reducing the number of bearings and seals they have to replace.

Key features
• Fast, easy, and precise alignment that adapts to your needs.
• Rugged build and the highest-in-class IP rating.
• Single-laser technology for the fastest, most accurate laser alignment.
• Cloud connection enables real-time collaboration.
• Use up to 8 measurement points to achieve precision alignment on vertical machines.

The Fluke 1535 and 1537 2,500 V Insulation Resistance Testers are engineered to simplify frontline troubleshooting whether you’re on the factory floor or working in the field at a solar installation. With user selectable test voltages from 250 V to 2,500 V and resistance measurements up to 500 GΩ these testers allow you to cover more workload with a single tool. Equipped with an intuitive user interface, a short circuit current of up to 5 mA and a CAT IV 600 V rating these portable high-voltage insulation testers can deliver rapid and stable resistance measurements no matter where you take them. The 1537 Insulation Resistance Tester also allows you to store measurements for later review or PC transfer, using the provided software.
• Selectable Voltage Tests: Tailor your tests with user-selectable voltages of 250 V, 500 V, 1000 V, and 2500 V to cover both industrial and solar applications.
• Extended Insulation Resistance Measurement: Reach up to 500 GΩ in insulation resistance measurement for a thorough analysis.
• Intelligent Calculations: Automatically calculate Polarization Index (PI) and Dielectric Absorption Ratio (DAR), minimizing the influence of environmental factors.
• High Measurement Capacity: Execute up to 1,300 measurements at 2,500 V or 6,500 measurements at 250 V on a single charge, enhancing productivity.
• Enhanced Safety Features: Benefit from a CAT IV 600V rating and a built-in voltage alarm function for heightened safety during operations.
The Fluke 1537 has these additional features:

Portable multi-function calibrator simplifies calibration work



Whether you're calibrating instruments, troubleshooting a problem, or running routine maintenance, the Fluke 754 with HART® communication can help you get the job done faster. It does many different tasks quickly and it's the only process calibrator you need to carry. This rugged, reliable, integrated communicating calibrator is ideal for calibrating, maintaining, and troubleshooting HART smart transmitters and other instrumentation.



Measurement and source capabilities:

- AC/DC voltage

- mA loop w/ 24V loop power

- Pressure

- Thermocouples & RTDs

- Frequency

- Resistance



Enhanced process calibrator operation



With the bright white dual display, you’ll be able to read both sourced and measured parameters simultaneously. The rechargeable Li-Ion battery offers up to 10 hours uninterrupted usage allowing you to complete one task after another without needing to stop, and also includes direct AC power capabilities if needed. Finally, communicate with HART smart digital transmitters directly through the mA measurement jacks for seamless calibration with fewer connections.



Do more, with less

The 754 does the work of several tools. It sources, simulates and measures pressure, temperature, and electrical signals with one rugged, hand-held device. The powerful built-in HART interface can perform nearly all day-to-day tasks you now perform with a separate digital communicator. It can handle fast-pulsed RTD transmitters and PLCs, with pulses as short as 1 ms. The 754 also measures/sources pressure using any of the Fluke 750P Series Pressure Modules as a reference and boasts many additional features like:

- Custom auto-step and ramping

- Custom units

- User-entered values during test

- One-point and two-point switch testing

- Square root DP flow testing

- Programmable measurement delay



Download procedures, lists, and instructions



The 754 is a power multifunction documenting calibrator that you can use to download procedures, lists, and instructions created with software, or upload data for printing, archiving, and analysis. The tool can hold up to a full week of downloaded procedures and calibration results and offers compatibility with many asset management software. Users can also create and run automated as-found or as-left procedures to satisfy quality programs or regulations, and records and documents results.



For documentation, the 754 automates calibration procedures and captures your data. And, of course, it helps you meet rigorous standards like ISO 9000, FDA, EPA, and OSHA regulations. Plus, the graphical screen, Li-Ion battery for longer life, USB port, and accessories help you work smarter and faster.
