Accuracy and traceability for infrared measurements

Now it’s easy to increase your IR temperature measurement accuracy with the new 4180, 4181 Precision Infrared Calibrators from Fluke Calibration. These infrared temperature calibrators give more consistent, accurate and reliable calibrations because emissivity is radiometrically calibrated, and the target size minimizes size of source effect errors. In addition, these infrared calibrators simplify calibration because they uniquely compensate for errors caused by thermometer emissivity settings.

New accredited performance for point-and-shoot calibrations
• Calibrated radiometrically for meaningful, consistent results.
• Accredited calibration included
• Accurate, reliable performance from –15 °C to 500 °C
• Large target size of 152 mm (6 in) is required for calibrating most thermometers.
• Light instrument weight of 8.6 kg (19 lbs) makes it easy to lift and carry.
• Intuitive, easy-to-read display that indicates when temperature is stable.

The Fluke 1507 is a versatile, compact, handheld insulation tester for advanced industrial and electrical insulation testing. Its multiple test voltages make it the ideal tool for many troubleshooting, commissioning, and preventative maintenance applications.
Take advantage of the 1507 full feature set to easily and quickly perform advanced insulation resistance testing. Its handy size and light weight make it easy to pack and use. Additional features, like the remote probe, save both time and money especially when performing repetitive tests. And its reasonable price and rugged reliability make it an excellent value.

• Runs on four AA alkaline batteries (NEDA 15 A or IEC LR6) for at least 1000 insulation tests

Key Features
• Rugged, compact advanced insulation resistance tester for electrical contractors and industrial and commercial electricians
• Automatically calculates Polarization Index and Dielectric Absorption Ratio
• Makes repetitive tests simple and easy with a Compare (Pass/Fail) function
• Offers multiple insulation test voltages: 50 V, 100 V, 250 V, 500 V, and 1000 V

• 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

The P3100 models are available in single or dual piston format. Unit can be supplied in psi, bar, kgf/cm², and MPa. This robust instrument is highly accurate, quick and easy to use. Units feature a built-in priming pump for large volume applications, piston flotation indicators and a high quality screw press for fine pressure control.
Operating principle
Deadweight testers are the high performance pressure standards for pressure measurement. Utilizing the well proven piston-gauge system consisting of a vertically mounted, precision lapped piston and cylinder assembly, accurately calibrated weight masses (Force) are loaded on the piston (Area), which rises freely within its cylinder. These weights balance the upward force created by the pressure within the system. The pressure is measured when placed on a correctly spinning and floating piston. The total pressure measured is the summation of the weights plus the piston weight carrier assembly.
Instrument base
There are three basic variations in the hydraulic offering; single low pressure, single high pressure and dual piston models. Pressure is generated and controlled by means of a high quality screw press located on the front of the tester. A built-in hand pump is included as standard for all hydraulic models to prime the system and accommodate large volume requirements.
Piston/cylinder assemblies
The piston/cylinder assembly is the heart of each deadweight tester. They are manufactured from materials that provide stability, durability, and low thermal coefficients and distortion. Our experience and knowledge of piston/cylinder production and calibration ensure the precision and performance required for today’s demanding calibration requirements.
Weight masses
Standard weight masses are series 3 nonmagnetic austenitic stainless steel. Each mass is marked with the serial number of the instrument and the nominal pressure value relative to the high or low-pressure piston, when applicable. Optional fractional weights are stainless steel and/or solution heat treated aluminum.
Gravity correction
Gravity varies significantly with geographical location and this variation has a direct effect on the force of the weights and the accuracy of the deadweight tester. Each instrument can be calibrated to local gravity at no extra cost. If unspecified, instruments will be calibrated to Standard Gravity at 980.665 cm/s2.
