The Portable and Highly Sensitive Allround Leak Detector for SF6 Components.


Based on the globally successful SF6 GASCHECK P1, the new SF6 LEAKCHECK P1:p was developed for a more mobile and convenient on-site leak detection. The portable version of the Allround Leak Detector is characterised by a high degree of reliability and measurement certainty, while at the same time being easy to use. The dimensions of the leak detector have been designed from the outset to comply with current hand luggage regulations.

For regular measuring operation, the only thing you need to do is switch the instrument on and off. Since the operator primarily does not need to measure a leak, but first to search and find it, P1:p automatically starts up in "search mode". In this mode, when the sniffer probe approaches a leak, the audio signal and optional vibration alarm as well as the analogue pointer all indicate full scale, signaling very clearly that an unknown leak has been found. Once spotted, the operator switches to "measurement mode" by pressing a key on the handset. The leak rate is now displayed in analogue and digital form in the desired unit of measurement, and a clear pass/fail indication based on the selected alarm threshold is given.

P1 Handgerät

All parts of the system subject to wear and tear are integrated in the plug-in SmartSensor. It can be replaced within a few seconds. As a result, maintenance intervals are longer and the availability of the P1:p is significantly increased. The 3 sensors included in the scope of delivery ensure that the P1:p is permanently ready for use.

Peli Protector Case 
For outstanding ruggedness, the instrument is built into a waterproof and unbreakable Peli Protector Case. The case is equipped with an automatic ventilation valve to accomodate to air pressure changes, e.g. during air transport. Its surface is resistant to corrosion, dents and scratches.

Unlimited Operation
The P1:p is suitable for worldwide use due to its wide range power supply from 100 to 240V - 50/60 Hz. The device also works for approx. 10 hours in mains independent battery operation. The charging process does not require monitoring, and the GASCHECK P1:p may by design remain connected to mains permanently. Where applicable, a standby mode can be selected to partially power down the P1:p when the handset is deposited for an adjustable period of time, saving both SmartSensor and battery life time. Return to normal operation takes place automatically when the hand unit is picked up again.
