Detachable Aquarium Probe, 6.6ft/2m, for Heating and Cooling Temperature Controller for Freshwater Saltwater Aquarium

It was unclear from the product description if I could use this with an ITC-308. When I purchased my unit I knew that the probe wasn't rated to be continuously submerged, but I took a chance. After a couple of years, the probe failed and it started reading well above my high alarm threshold. I ordered this replacement sensor and installed it. The sensor works great, is now designed to be used submerged, and it has a plug so if I need to replace it again I can easily swap it out.

It works. I use it for my temperature controller for a freshwater aquarium set up. I would recommend the product. Only issue would be that they need to replaced every few years. They randomly just stop working properly after a few years.

Thanks inkbird for offering an upgrade/ replacement so I didn't have to junk my whole temp controller unit. I like the plug and waterproof sensor in this version. It's sure to help me avoid damaging it in the future.

Ordered two days ago. I went with this plastic probe as my metal one went haywire past few weeks. You can only calibrate broken one for so long. Received today and installed today with the butt splice method. Calibration is required as this was .5 degrees cold calibration done side by side with a digital calibration as well as my trusty kitchen thermometer. I agree with another reviewer that the plug should be attached rather than having to either butt splice/solder/electrical tape. So silly. But the finished product is nice. The connector to plug in is cool to have. Make sure you plug in firmly or you’ll get an error code. Glad to have my keezer up and running in short order.

The old probe was reading 125⁰F on my inkbird 306T wifi. Open the back with a screw driver, then snip the old leads strip and solder the new leads onto the old. Now it's reading normal temps. I would gladly rate this replacement part 5 stars if they put the plug that's on the board on the replacement probe. Atleast the fix should be one and done, if it happens again it's a quick headphone type jack to plug in the new one.

My temperature probe went bad at just about a year of use. I was happy that I found this replacement. I used two butt splice connectors to wire it into the controller. Quick and easy repair and I’m back up and running. Sure beats buying a whole new unit.

Was skeptical from the reviews that said it didn't come with the pig tail. Mine came with the pigtail end. I soldered it onto the board, keeping mind which hole was for the white wire. Plugged in the new probe and it worked great. Old probe was reading 107, over 20 degrees high. I read online that after about 3 years probes can drift. This new one reads accurately :)

Original hardwired metal-tip probe on ITC-308 controller failed after several years, began giving very high temp readings. Installed this probe as replacement, controller now working again. Product description incorrectly says that probe "only" works with model ITC-308S. Open back of controller, remove circuit board, un-solder hardwired probe, replace with new pigtail connector, re-assemble, attach new probe to connector, then plug in controller and test.

Excelente repuesto lo conecte y funcionó perfectamente
