2nd probe By Devo on 12/8/2014Devo would recommend this product to a friendi got this 2nd probe to put in my QT to help keep my temp in check and its doing great!
Nice Probe By Terri on 12/3/2014Terri would recommend this product to a friendAfter a little over a year, the probe which came with my Apex began showing large temp swings. I replaced the heater and there was no change so it had to be the probe. I ordered the replacement above. No more erratic readings! This probe is well built. The cord is very long which I needed!
Solid Product By JohnD on 7/13/2014JohnD would recommend this product to a friendI'm very pleased with this probe and it is definitely build to handle the harsh saltwater. I've been using Neptune temp probes for years and I've never had one fail.
Accurate By Reefsi on 4/20/2014Reefsi would recommend this product to a friendHave 2 of these both read within .2 of eachother at all times. Get a .4 higher reading than using the coralife cheapos which is strange but I know that the Neptune ones are accurate and well made.
Low Cost and Dependable By Jared on 11/14/2013Jared would recommend this product to a friendI have three of these units actively running. I calibrated each one via the web interface with a NIST-Traceable Temperature Probe. This neptune probe is made well, and all three have maintained their accurate values for well over a year of use so far. All three are submerged.

Will the probe work for air temperature as well, or does it need to be submerged? (i.e. could I use it for terrarium temp. regulation)
Bulk Reef Supply Hi Evan,
The probe will work but likely wouldn't be the best choice for air. Water conducts heat much better then air so the probes for water have more mass to keep the reading from fluctuating wildly. Air doesn't conduct heat very well so temperature sensors intended for air tend to have very low mass, that way there is less material that needs to be heated for the sensor to recognize it. The bigger/heavier the probe the slower it will respond and less accurate it will be for air.

Do I need a PM2 to add a second temp probe to my Apex controller? It's not the jr.
Bulk Reef Supply Hi Gary,
To add a second temp probe you would need a probe module. The PM2 would work as well as the PM1.
