Introducing Milwaukee Instruments

Single Measurement – Portable Meters

Aquaponics MW 100 pH Meter

MW 100 and MW 101 pH Meters

About pH: The pH value of a solution is a measure of its acidity or alkalinity. A basic, neutral solution measures 7 on the pH scale. As a solution gets more acidic, the pH value will decrease. As the solution becomes less acidic, or more alkaline, the value will increase. The pH scale ranges from 0 pH (very acid) to 14 pH (highly alkaline). Pure water has a pH of 7, indicating that it is neither acidic nor alkaline, but neutral. To learn more about pH requirements for aquaponics, click over to our Water Page.

Milwaukee warrants all products to be free of defects in material and workmanship as stated in the operating manual. If repair or adjustment is necessary and has not been the result of abuse, misuse or improper handling within the warranty period, please contact your dealer or the Technical Service Department at Milwaukee for an RGA (Returned Goods Authorization) number to put on the outside of your freight prepaid package. Warranted service will be made without charge.

The warranty is void if the instrument is repaired or serviced by unauthorized personnel, not used in accordance to the instructions, or if non-Milwaukee accessories such as buffer solutions, electrodes, probes etc. are used in conjunction with the meter.

The warranty period commences from the original date of sale and is valid on the date Milwaukee receives the warranty registration form.

The above statement is a quote from our System Engineer and Aquaonics Expert, Oliver Duffy, who because he's a retired Aerospace Engineer knows all about taking measurements and being precise. In AP Sysems measuring your Water Quality is the most important because poor Water Quality means dead Fish and dead Fish means dead Plants. There are lots of other things that can also be measured like your Dissolved Oxygen (DO) Levels and your Light (LUX) if you're using LED's. That's why we recommend Milwaukee Instruments.


Measuring things is so important, every STEM & Family PLUG & GROW™ Food Growing System we sell includes AI Tracking Software complete with a Mobile AP! This Software makes measuring and tracking your Water Quality a snap, and we can see what's happening, too.
