Hi,
We have 11 FlowTracker2 (FT2) kit, bought from 2017 to 2022. We really like them, but we had also some trouble.
– One handheld unit when dead while measuring; we had to send it back for repair (finding : major short ckt. on Toradex board)
– Four (4) probe had a low SNR problem ; had to send then back for repair (finding : internal wire broken)
– One probe had a broken mounting stem. Had to be replaced.
Despite all that, we are still optimistics with the FT2 and largely use them. All the repairs were done under warranty or goodwill.
