The Fluke 1507 and 1503 insulation testers are handy, robust, reliable and easy to use. Since they have multiple test voltages, they are ideal for troubleshooting, set-up and preventative maintenance. - Insulation testing range: 0.01 Mohm to 10 Gohm - Insulation testing voltages: 50 V, 100 V, 250 V, 500 V, 1000 V - Automatic calculation of the polarisation index and dielectric absorption level - With the Compare function (good/bad) repetitive tests can be performed quickly and easily - A probe with release button makes repetitive tests or tests on hard-to-reach objects easier - Detection of live circuits prevents insulation tests at voltages over 30 V and thus increases the protection of the user - Automatic discharge of capacitive voltages for higher protection for the user - AC/DC voltage: 0.1 V to 600 V - 200 mA continuity - Resistance: 0.01 ohm - 20.00 kohm - Automatic shut-off to save battery power - Large backlit display for easy reading of measurements - Overvoltage category CAT IV 600 V for increased protection of the user - Probe with release button, test leads, test probes and crocodile clips included - Mounting options for the optional magnet holder Fluke TPAK for hands-free operation - Four alkaline batteries type AA (NEDA 15 A or IEC LR6) for more than 1000 insulation tests Included with delivery TP165x slim probe with release button TL224 SureGrip silicon test lead set TP74 probes with pointed 4 mm banana plugs Crocodile clips User manual 4 AA batteries AC and DC voltage measurement Inaccuracy Range: 600.0 V Resolution: 0.1 V 50 Hz to 400 Hz ± (% of MW + digits) ±(2% + 3) Input impedance: 3 Mohm (nominal), Common-mode rejection ratio (1 kohm unbalanced): > 60 dB at DC, 50 Hz or 60 Hz Overload protection: 600 V effective or DC Protective conductor resistance measurement Range/resolution: 20.00 ohm 0.01 ohm 200.0 ohm 0.1 ohm 2000 ohm 1.0 ohm 20.00 kohm 0.01 kohm Inaccuracy: ±(1.5% + 3) Overload protection: 2 V effective or DC Idle test voltage: > 4.0 V, Short-circuit current: > 200.0 mA Measuring and test functions Measuring range: 0.01 Mohm to 10 Gohm Test voltages: 50 V, 100 V, 250 V, 500 V, 1000 V Inaccuracy of the test voltage: + 20%, - 0% Short-circuit current: 1 mA nominal Automatic discharge: discharge time Display for power circuit: prevents the test if external voltage before the beginning of the tests > 30 V Maximum capacitive load: can be operated with up to 1 µF load Inaccuracy when measuring: 50 V: ±(3% + 5) 100 V: ±(3% + 5) 250 V: ±(1.5% + 5) 500 V: ±(1.5% + 5) 1000 V: ±(1.5% + 5) up to 2000 Mohm, ±(10% + 3) over 2000 Mohm https://elecena.pl/product/18101336/2427890-fluke-insulation-tester-1507 2021-04-30 https://elecena.pl/product/18101336/2427890-fluke-insulation-tester-1507 2021-10-22 https://elecena.pl/product/18101336/2427890-fluke-insulation-tester-1507 2021-12-12 https://elecena.pl/product/18101336/2427890-fluke-insulation-tester-1507 2022-03-17 https://elecena.pl/product/18101336/2427890-fluke-insulation-tester-1507 2022-08-15 https://elecena.pl/product/18101336/2427890-fluke-insulation-tester-1507 2023-05-10 https://elecena.pl/product/18101336/2427890-fluke-insulation-tester-1507 2023-10-23 https://elecena.pl/product/18101336/2427890-fluke-insulation-tester-1507 2024-03-26 https://elecena.pl/product/18101336/2427890-fluke-insulation-tester-1507 2025-04-08 https://elecena.pl/product/18101336/2427890-fluke-insulation-tester-1507 2025-05-18 https://elecena.pl/product/18101336/2427890-fluke-insulation-tester-1507 2025-05-24 https://elecena.pl/product/18101336/2427890-fluke-insulation-tester-1507 2025-06-04 https://elecena.pl/product/18101336/2427890-fluke-insulation-tester-1507 2026-03-04
