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.

This versatile instrument provides calibrations from 1-30 inHg vacuum (0.03-1 bar) and 3-500 psi (0.2-35 bar) in one extremely accurate yet easy to use primary standard. A selector valve converts the unit from pressure to vacuum mode without the need to exchange pistons. Units are manufactured to the highest standards with certified accuracies traceable to International Standards Laboratories such as the National Institute of Standards and Technology (NIST). These piston/cylinder type pneumatic standards provide excellent stability, repeatability and accuracy. An optional built-in hand pump can be added for both pressure and vacuum generation.

Key features
• 0.015% of reading accuracy standard (0.008% optional)
• 1-30 inHg vacuum (0.03-1 bar vacuum)
• 3-500 psi (0.2-35 bar) pressure
• inH2O and mbar ranges available
• Series 3 non-magnetic stainless steel weights
• Units can be trimmed to local gravity FOC

Product overview: Fluke Calibration 1620A Precision Thermo-Hygrometer
Accuracy
The standard-accuracy sensor (“S” model) reads temperature to ±0.25 °C over its calibrated range of 15 °C to 35 °C. Relative humidity readings are to ±2% RH from 20% RH to 70% RH.
All DewK sensors come with accredited certificates of calibration for both temperature and humidity, complete with data and NIST traceability.
Ethernet and wireless capability
With its built-in Ethernet RJ45 jack, multiple DewKs can be monitored from the same screen using Log Ware III client-server software. Ethernet also gives you the possibility for remote connectivity over the internet, so you can monitor critical conditions while you’re away.
Cables running along the floor can be a safety hazard, and cables hanging from the ceiling and walls are an eyesore. With the DewK, simply connect your computer through an RF modem up to 100 ft away, without the clutter of all the extra cables.
If you need a printout, send data to a printer through the RS-232 interface in real time.
Math and statistical functions
In addition to temperature and humidity, the DewK calculates dew point, heat index, and rates of change for both temperature and humidity. Min, max, and a variety of other statistics are also calculated and can be shown on-screen. Daily summary statistics, including min, max, and maximum rates of change are stored for the most recent sixty days.
Calibrated sensors
With inputs for two sensors, each measuring both temperature and relative humidity, one DewK can monitor two locations at the same time. Both sensors can be run via extension cables to remote locations up to 100 feet away, or one sensor can be directly mounted to the top of the DewK.
Each sensor is calibrated for both temperature and humidity by Fluke Calibration. The calibration constants assigned to the sensors reside in a memory chip located inside the sensor housing, so sensors may be used interchangeably between different DewKs, and the recalibration of sensors doesn’t require an accompanying DewK.
Sensors may also be assigned a unique identifier (up to 16 characters) to facilitate record keeping by matching the sensor identifier with the collected data. Each DewK ships with one sensor, with additional sensors available directly from your local Fluke Calibration sales representative, or directly from Fluke Calibration. Spare sensors may also be purchased from Fluke Calibration as a kit, which includes a case for the sensor, a wall mounting bracket, and a 25-foot extension cable.
Memory
The DewK has enough on-board memory to store up to 400,000 date- and times stamped data points. That’s two years' worth of data for both measurements from two sensors if readings are taken every ten minutes!
Alarms and battery backup
Alarm settings can be set up quickly in the DewK based on temperature, the rate of change in temperature, RH, the rate of change in RH, and instrument fault conditions. Alarms can be both visual (flashing display) and audible (beeping). Likewise, alarm settings can be set up and events triggered in Log Ware III. The DewK is also equipped with a 0 to 12 volt alarm output that can trigger a process control system.
A backup battery shuts down the DewK’s display but maintains measurements for up to 16 hours in the event of a power failure.
Large, easy-to-read display
Want to view data from across the room? Want to view data from two temperature and two humidity inputs simultaneously? Want to view data graphically, statistically, or both? At the same time?! The DewK does everything you could want—or at least everything we could think of. Up to sixteen different display setups can be stored and recalled at the touch of a single button. And all 16 can be easily modified, so you get exactly what you want.

Manufactured from high quality polished steel. Ground finished points, a fine adjusting screw is mounted across the legs for setting the distance between the two points. A circular spring bow joins the legs, with a knurled extension attached for use when pivoting the dividers. Dividers are used for scribing arcs and circles, a light centre punch mark on the work keeps the pivot leg in the centre while marking.
