Please find here our offer for the requested spark tester.
We offer both versions of spark tester as you requested.
Please note that you should have at least 250mm electrode length to check production speeds up to 300m/min according to IEC standards
Please note that only one to the offered systems is fulfilling this electrode length.
As discussed we offer also one spark tester with 40kV in order to reach the requested 30kV. The second system however is limited to 25kV, but would have the longer electrode to assure the 300m/min line speed according to IEC standards.
I leave this up to you to discuss with your team.
Let me know in case you need additional information
