The Elcometer 266 DC Holiday Detector provides accurate detection of pinholes, flaws, inclusions, thin spots and bubbles in a coating. The gauge has been specifically designed to revolutionize high voltage DC testing of coatings, making it safer, easier and more reliable than previously possible.• Current limiting to avoid coating damage:When the 266 detects a flaw, and sparks, the current flow reduces to a low level, minimizing risk to both the user and the coating.• Automatic voltage calculator:No need for lookup tables, simply enter the coating thickness value and select the standard and the gauge will automatically set the voltage.• Safety hand grip: Ensures that high voltage can only be generated when the handle is being held.• Internal jeep tester: Removing the need for 2 gauges. The closed loop system with internal voltmeter guarantees the voltage output at all times.• Specialized handle design: Extended ribbing on the handle provides an effective barrier between the high voltage and the user.• Rugged and waterproof to IP65: Rugged, waterproof IP65 case is sealed against the elements.• Accurate sensitivity adjustment: Allows use on metallized or slightly damp coatings.• Rechargeable & replaceable battery packs: Battery packs can be charged inside or outside the gauge.• Interchangeable handles: 0.5 - 5kV, 0.5 - 15kV or 0.5 - 30kV adjustable in 0.1kV steps.• High Voltage Output Accuracy: ±5% or ±50V below 1000 Volts • Measured Current Flow Accuracy: ±5% of full scale • Display Resolution: 100 Volts, 1?A • Output Current: 0 - 100?A maximum • Operating Temperature: 32°F to 120°F (0°C to 50°C) • Power Supply: Internal rechargeable lithium Ion battery • Instrument Case: High impact ABS • Earth Lead Length: 394” (10m) • Dimensions: 20.5L x 14.5W x 5D” (520L x 370W x 125Dmm) • Weight: Base unit (with battery pack) 2.7 lb. (1.2kg) Handle: 1.3 lb. (0.6kg)
