New!!! Fluke 1555/1550C
Insulation Resistance Tester Digital insulation testing up to 10 kV. 
Ideal for testing high voltage equipment.

The new Fluke 1555 and redesigned Fluke 1550C insulation resistance testers, offer digital insulation testing up to 10 kV, making them ideal for testing a wide range of high voltage equipment including switchgear, motors, generators and cables. With measurement storage and PC interface, the 1555 and 1550C are perfect tools for preventative or predictive maintenance programs designed to identifypotential equipment failures before they occur.

Features include:

• Test voltages to up 10 kV provides solutions for all applications
• CAT III 1000 V, CAT IV 600 V safety rating
• Warning function alerts the user that line voltage is present and gives the voltage reading up to 600 V ac or dc for increased user safety
• Selectable test voltages in 50 V steps from 250 V to 1000 V, and 100 V steps above 1000 V
• Measurements can be stored in up to 99 memory locations, with each location assigned a unique, user defined, label for easy recall
• Long battery life gives the user over 750 tests between charges
• Automatic calculation of Dielectric Absorption (DAR) and Polarization Index (PI) with no additional setup
• Guard system eliminates the effect of surface leakage current on high-resistance measurements
• Large digital/analog LCD for easy viewing
• Capacitance and leakage current measurement
• Ramp function for breakdown testing
• Resistance measurements up to 2TΩ
• Timer settings up to 99 minutes for timed tests
• Operates in any unit of measure while deadweight tester is typicall limited to the pressure unit stamped on the mass
• Perfect for applications that require setting a nominal pressure precisely on the device under test and measuring it, such as analog gauge calibration
• On-board, AutoTest calibration routines and data acquisition
• Interfaceable with a PC or laptop to allow for automated data acquisition
• Two year calibration interval supported at measurement uncertainty of ± 0.025% of reading.
• Easily recalibrated without crossfloating. Automated calibration of E-DWT-H is possible using COMPASS® for Pr
