## Description

Milwaukee Instruments MA911B/2 Double Junction Ph Electrode with 2 m Cable and Gel Filled Electrolyte Solution by Milwaukee : desertcart.in: Industrial & Scientific

Review: very good value - I bought this to replace my old one that I had installed for just over 4 years. it was only after 4 years of permanent usage in my fish tank set up when it became inaccurate. Some person before me commented that if it is meant to be used in a aquarium then why is it bright yellow? Well, I guess they read the comment as well because the one I got sent is green. For me it doesn't matter as it is installed in a sump but for those who put it straight in the tank it is a nice change.
Review: Good probe but make sure you give it time to settle in - Using this in a reef tank. Cheaper than the Neptune Apex probe and works just as good. Word of warning, let it sit in the tank water for a a week before calibration. This probe ships with a KCl gel to keep the probe hydrated. Around day 5 in my tank, some of this gel that had worked its way up into the probe started to expand and offset my readings by about 0.25. Thinking it was some kind of tank goo, I just gave it a swirl. Later, I see my PH spike back to a "normal" reading. Other than that, this probe has worked well so far. It's been accurate (when not blocked) and consistent. I included a screenshot of my PH graph to show how things seemed fine for a few days, then the gel likely blocked the junction and PH was "suppressed" for a couple days before the huge spike at the end when I notice the gel/cleaned the probe.

## Questions & Answers

**Q: Will this work with the Milwaukee SM802 meter?**
A: You would want a combo probe for your meter since it measures ph and TDS, so you would want MA850 combination pH/EC/TDS probe,

**Q: Will this work with Model MW 100?**
A: It should. Looks like your Mw100 has a BNC connector for the probe, that's what this replacement has which is pretty industry standard and the range looks to be same as well.

**Q: Will this work a milwaukee mw 102 or milwaukee mw 101 meter ?**
A: Im not sure, however if it has a BNC connector they are pretty generic and I believe it would work

**Q: Is this probe threaded, so it can be used in-line of a circulation system?**
A: NO, it is not threaded, However you can purchase a threaded adapter that the probe slides into and tighten it down to form a seal. Thats how I use mine on a calcium reactor. Good Luck
