Testo 0613 5505 NTC Clamp Probe, -40 to +125 degree C Range

Price high but needed it.

ok I guess would buy again

If you're buying a replacement you already know it's not the best quality. I already bought 3 of them over the years and finally switched to a diff brand. I wish they would make a better design where it can lock, snap-lock, or be bump resistant because of those connections. Even the good ones wiggle and it doesn't take a lot for them to be loose.

Product is okk

Dislike

Exactly as advertised

Got this for my 550 set since it only comes with one. This is not the most durable clamp but it works. Already had the clamp handle snap. This sensor style takes longer then K-type sensors to read but is pretty accurate once its in the zone. Only other issue is sometimes the pipe size will have this thing sitting awkwardly and have me second guessing if the sensor is fully seated against the pipe. Overall not bad though given that you have to use this if you have the testo sets.

Had to purchase this for my testo 550 due to my other pair i bent the pronges on the plug. Did not expect the high price on these.

Working good. Cable size is small, easy to damage. Gentle with it then ok. 2 were damaged, this is my third one.
