ISOTEST - Model 4S -Holiday Detector
The ISOTEST 4S Holiday Detector is engineered for rigorous on-site applications, leveraging impulse voltage technology to deliver highly precise testing with automated regulation. The device features an adjustable test voltage range of 10-25 kV in 0.5 kV increments, unipolar high voltage pulses, and a pulse duration of 10 μs at a frequency of 25 Hz. Equipped with a graduated switch and status LED for operation and indication, it produces acoustic signals up to 86 dB. It includes a lead-acid rechargeable battery (6 V / 4.5 Ah) with a runtime of up to 9 hours. The device measures 280 x 230 x 120 mm and weighs 4.5 kg with accessories, while the battery alone weighs 0.9 kg. It comes with a 1.5 m high voltage cable and provides an IP42 protection rating, operating in temperatures from 0°C to 50°C, and can be stored between -20°C and 50°C. Its robust construction ensures dependable performance in challenging environments, aiming to provide reliable test results across various industrial settings.- test voltage 10 - 25 kV, 5 kV steps
- robust testing device for construction site operation
- multi-stage sensitivity adjustment
- patented automatic regulation
- power reserves for the highest requirements
- self-calibrating instrument
- testing of dirty, damp and therefore slightly conductive surfaces
- three grounding possibilities, including capacitive grounding (Phantom-Grounding)
- no static charge of the text object
