ISOTEST - Model act P2 -In-plant Holiday Detector System
The ISOTEST act P2 In-plant Holiday Detector System is designed for thorough inspection of industrial pipe coatings, including FBE and 3 layer PE/PP. It operates with test voltages from 2.5 kV to 25.0 kV, providing flexibility in detecting holidays and other coating damages. Its multi-channel capability supports up to 6 test channels configured in master/slave mode, and it is powered by a wide range voltage supply (100-240 VAC or 90-375 VDC). The system ensures high operational reliability with continuous operation across three shifts, stabilizing test voltage through load-dependent regulation. Indications of porosity and operational alerts are documented via display indications and potential-free contacts. The ISOTEST act P2 maintains compliance with all relevant safety and EMC standards, including DIN EN, ISO, and DVGW. With a high testing speed of up to 1200 mm/s and robust environmental tolerances (0°C to +50°C at a max 60% relative humidity at 30°C), this system is suited for rigorous industrial application.- porosity testing of FBE and PE / PP coatings with a single device
- test voltages 2.5 kV / 3.0 kV / 3.5 kV / 4.0 kV / 10.0 kV / 15.0 kV / 20.0 kV / 25.0 kV
- high-voltage pulse technology
- no static charging
- testing according to DIN 30670
- testing of dirty, damp and even slightly conductive pipe coatings
- up to 6 test channels - synchronisation of several devices (master / slave mode)
- “Phantom-Grounding“ – no direct grounding necessary
- external switch-on / switch-off of the test voltage
- adjustable sensitivity and filter functions
FBE and 3 layer PE / PP pipe coatings can reliably be tested for holidays or other damages with a single device.
You can count on ...
- a compact “all-in-one” device (control unit and high voltage generator in a single compact housing)
- continuous operation (three shifts)
- porosity / leak testing of all non or slightly conductive materials
- external switch-on / switch-off of the test voltage
- increased operator safety – thanks to the combination of impulse voltage and smart power control
- stable test voltage, even under demanding conditions, guaranteed by load-dependent regulation of energy
- high testing speeds made possible by optimised pulse repetition frequency
- detection and display of even the smallest holidays and voids by the integral evaluation process – with minimal material stress
- electrostatic charges – a latent risk for DC devices – are excluded by the use of impulse technology when properly grounded
- testing of fully coated test objects – even without direct grounding – enabled by the option of “Phantom-Grounding”
All ISOTEST® holiday detectors have undergone extensive tests in the field of safety and EMC. They all carry the CE label and fulfil the requirements of all relevant standards and specifications (DIN EN / ISO / DVGW etc.)
