## Questions & Answers

**Q: How long is the cord?**
A: It's about 3 feet long

**Q: I'm going to use this with an Arduino to keep a tab on my aquaponics system. Do I need to buy a pH circuit, BNC connector, and analog cables for this?**
A: It terminates in a BNC connector but you will need a circuit to produce a nice voltage range. I forget the math and numbers precisely but it's something like 25 mV difference at STP for pH meters between log pH units, so you'll need something to amplify that voltage and map it e.g. from 0-5V. One outfit that sells pH electronics boards is called Atlas Scientific. There's a great instructable doing exactly what you want to do: http://www.instructables.com/id/ORP-pH-Temperature-Data-Logger/?ALLSTEPS <--- if link doesn't work, search instructables for "ORP pH Temperature Data Logger"

**Q: Can this be used to measure the pH of soil? Can it be kept in soil 24/7?**
A: Techniques for measuring soil pH involve more than sticking a probe in the mud.   I recommend finding a protocol online for performing this test with a pH meter and probe.   These probes must be carefully cleaned after use and stored in an appropriate solution.   Do you have a pH meter?

**Q: How often does the probe needs to be calibrated? once per month? more/less than that? (i intend to always let it on the water)**
A: only once a year, have not had any problem with this probe....

## Customer Reviews

### ⭐⭐⭐⭐⭐ Good
*by L***M on 24 May 2021*

Good quality but cable too short check your needs before buying

### ⭐⭐⭐⭐⭐ Five Stars
*by R***U on 19 October 2015*

Is a good very reactive/well made pH probe am very happy with my purchase.

### ⭐⭐ Not a 100% reliable seller/make
*by M***A on 30 December 2024*

In 2024 I bought 3 probes for my reef tank, previously I had bought 2 probes (same make) about 2 years ago (that worked just fine):- one of the probes had signs of scractes on the body, which I kind of ignored... how naive was I - the probe drifted 0.3 PH points within a 2 week time!- other 2 probes are OK..From what I can conclude - if someone returns the probe because it's faulty, the seller just repackages and ships it on to the next customer. Not going to buy Extech again and definitely not from this shop - would rather pay for a proper Milwaukee double junction probe.
