Fluke 741B Documenting Process Calibrator
We know how tough your job can be. You've got a lot to deliver in as little time as possible. So we've made it easier on you - with our multifunction 740B Series Documenting Process Calibrators.
The 740 Series does the work of several tools - sourcing or measuring pressure, temperature, and electrical signals in one rugged, hand-held device.
For documentation, the 740 Series automates calibration procedures and captures your data - for easy transfer to a PC using Fluke DPC/Track software or other popular packages. And, of course, it helps you meet rigorous standards like ISO 9000, FDA, EPA and OSHA regulations.
The 740 Series is easy to use with flexible test strategies, user-entered values, custom units, even a built in calculator. And like all Fluke tools, it's rugged, reliable and tough as nails. It's like having several powerful tools in one - so you can work faster than ever:
- Calibrate temperature, pressure, voltage, current, resistance, and frequency
- Measure and source with one compact, rugged, reliable tool
- Create and run automated as-found/as-left procedures Supports linear, square-root devices plus one-point and two-point limit switches
- Record and document results
- Transfer the results to a PC (743B and 744 only), saving the time to manually transcribe data. Run popular instrumentation management software.
- HART communication capability lets you program and control HART instrumentation (744 only)
The Fluke 740 Calibrators, offered in three models, let you choose the
right set of capabilities for your needs:
- The Fluke 741B offers simultaneous source and measure capabilities for all common process parameters. Create and execute automated procedures and automatically capture the results.
- The Fluke 743B offers all the capability of the 741B, plus adds a serial interface for two-way communication applications
- The Fluke 744 offers all of the capabilities of the 743B, plus the ability to maintain and calibrate selected HART transmitters without a second tool.
The 741B is the economical choice for plants that don't use PCs or that require traditional paper forms. It has storage capacity for a day's calibration and measurement data. When you're back at the shop recall the data on screen to fill out calibration forms.
Features:

Allow you to quickly set up powerful, automated calibration procedures for linear transmitters, DP flow transmitters, and one- and two-point limit switches. Simply select the appropriate measure and/or source functions and fill out the procedure template. The 740 Series does the rest. It quickly performs the test, calculates the errors, and displays the final results, highlighting out of tolerance points.
Enable you to map one unit to another, such as mV to C or F. Allows you to use the Fluke 740 Series with millivolt output accessories such as the Fluke Temperature Probe, and to document tests using non-supported units such as parts per million or revolutions per minute.
Enables technicians to record calibration results that were sourced and/or measured by other devices such as panel meters or readout-only devices. Procedures perform fast, automated calibration of one and two-point limit switches for voltage, current, temperature, and pressure. Routines use a square root function to directly calibrate DP flow instruments.
Multifunctional
Calibrate temperature, pressure, voltage, current, resistance, and frequency. Since it both measures and sources, you can troubleshoot and calibrate all with one rugged tool.
Powerful, yet easy to use
The easy-to-follow menu-driven display guides you through any task. Get up to speed in minutes, not days. Programmable calibration routines enable you to create and run automated as-found/as-left procedures to ensure fast, consistent, calibrations.
Records and documents results
To support your ISO-9000 or regulatory standards the Fluke 741 captures your calibration results, eliminating the need to juggle a pen and pad in the field.
Truly hand-held
Small enough to fit easily into a tool bag and to use in tight spaces. Runs an entire shift on a rechargeable NiCd battery pack.
Rugged and reliable
Count on Fluke's rugged design to deliver top accuracy and reliability in harsh environments. Overmolded urethane case stands up to rough handling in industrial environments.
Bright white display
Lets you read your results in any kind of light.
Soft keys
Provide one-touch access to enhanced functions such as task lists, automated procedures, scaling, min/max, stepping and ramping, and review memory.
Three operating modes
Measure, Source, or simultaneous Measure/Source, - enable technicians to troubleshoot, calibrate, or maintain instrumentation with just one tool.
Multi-lingual interface
Displays instructions in English, French, German, Spanish, and Italian.
Built-in algebraic calculator
With four functions-plus square root-stores, recalls, and performs calculations required for setting up instruments or evaluating data in the field. Use it to set the source function to a calculated value. There's no need to carry a pencil and paper or a separate calculator.
Programmable measurement delay
Inside automated procedures permits calibrating instruments that respond slowly.
