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.

• Cloud connection enables real-time collaboration.
• Use up to 8 measurement points to achieve precision alignment on vertical machines.

• 3 phase indication

• Indication of phase rotation

• Clear LCD display

• No battery required

Fluke 721 Precision Pressure Calibrator provides pressure calibration and temperature measurement for custody transfer applications



The Fluke 721 Precision Pressure Calibrator is the ideal tool for gas custody transfer applications. It features dual isolated pressure sensors to allow you to take simultaneous static and differential pressure measurements with a single tool. And it can be configured by selecting either a 16 psi (1.1 bar) or 36 psi (2.48 bar) low pressure sensor then adding any of seven high pressure ranges: 100, 300, 500, 1000, 1500, 3000 or 5000 psi (6.9, 20, 24.5, 69, 103.4, 200, 345 bar).



Other useful features:

- Measures up to 30 V DC, checks 24 V loop power supplies

- Extends pressure measurement range with connection to external 750P

- 750 series pressure modules (50 ranges)

- Provides a large backlit graphic display that can show up to three inputs simultaneously

- Stores five instrument setups for recall

• Be aware of voltage easily - the tip glows red and a beeper sounds when voltage is detected

• Continuous self-test so you always know it’s working

• Voltage detection range for wide application use - 90 V to 1000 V AC or 200 V to 1000 V AC

• Audible/Silent mode for added convenience
