CARE AND USE

MAINTENANCE

EC/PPM electrodes can develop nutrient buildup over time. To minimize buildup, always rinse the probe in fresh tap or DI water after every use.

CONVERTING TDS TO EC

The Milwaukee TDS/PPM Pen, like all TDS meters, provides a reading measured in parts per million of contaminates per unit of volume in a solution.

TDS/PPM is often converted to uS/cm. Different scales include the 500 scale, 650 scale and the 700 scale. 

Your TDS/PPM reading can be approximately converted to uS/cm as shown in the examples below.

1 ppm = 2 uS/cm on the 0.5 factor scale
1 ppm = 1.43 µS/cm on the 442 scale or .70 factor scale

Outstanding! An absolute must for college students
Format: Paperback
I picked this book up hoping it would prepare me for the job market, which I was already pretty confident about. It was incredibly eye opening, and enlightened me about dozens of things I was overlooking--like using Facebook as my "professional friend" and getting a linkedin account. It was a little stressful seeing how much I could do, but I've been working through the tips one at a time and its really built momentum in my professional brand even as an undergraduate. Now, I have something to do to build my career everyday.

Made Me Examine My Own Hidden Prisons -- Powerful and Empowering
Format: Hardcover
I was fortunate to read Shaka's book early, and it stands as one of the most profound self-help books I've ever encountered. The experience reminded me of reading MAN'S SEARCH FOR MEANING -- that rare combination of beautiful, raw writing paired with hard-earned wisdom born from lived experience. What sets HOW TO BE FREE apart are the "Digging Deeper" sections at the end of each chapter, which offer straightforward, specific guidance for breaking free from the hidden prisons that keep us from reaching our potential. These aren't vague platitudes; they're practical tools you can actually use. While my privileged upbringing couldn't be more different from the experiences Shaka writes about, I quickly discovered that the hidden prisons he explores -- grief, anger, struggles with forgiveness and vulnerability, etc -- are universal. They affect all of us, regardless of our background or circumstances. As someone who loves introspection, I found myself genuinely engaged in examining my own hidden prisons and what holds me back. The book doesn't just tell you about these barriers -- it makes you want to dig into your own. What his journey gave me wasn't just insight, but confidence. If he could find his version of freedom from solitary confinement, then I have no excuse not to pursue mine. The writing itself is incredible -- authentic, compelling, and beautifully crafted. I'd read anything Shaka wrote. This book doesn't just teach you about freedom; it shows you the path to find your own.

Feeling Stuck in Self-Doubt or Fear? This Book Unlocks the Hidden Prisons Holding You Back!
Format: Hardcover
That’s exactly where I was—stuck in what Shaka calls “Hidden Prisons.” Reading How to Be Free felt like someone handed me the key I didn’t know I already had. This isn’t just another “self-help” book filled with fluffy affirmations. Shaka earned his wisdom the hard way—19 years behind bars, 7 of them in solitary confinement. And yet, out of that darkness, he forged a blueprint for freedom that applies to EVERYONE: CEOs, parents, students, athletes… anyone who’s tired of being stuck. What I loved most? The book doesn’t just inspire—it gives you tools you can actually use. Daily practices like journaling, mindfulness, and meditation aren’t presented as clichés but as lifelines. I tried just one of the exercises and immediately noticed a shift in my mindset. 🔥 My biggest takeaways: Your setbacks can fuel your greatest comebacks. Vulnerability isn’t weakness—it’s power. Protecting your peace is just as important as chasing success. True freedom starts in the mind, long before circumstances change. If you’ve ever battled shame, anger, or the feeling that life is slipping through your fingers—this book is the wake-up call you need. By the time you finish How to Be Free, you won’t just believe change is possible—you’ll have a clear path to living it.

Profoundly powerful.
Format: Audiobook
I found this book incredibly powerful. A clear, courageous guide to living unbound. An invitation to drop inherited scripts based on adopted norms - think of guilt, grind, respectability - and instead find a path to peace, integrity, and self-trust. I'm a big fan of The Artist’s Way, which helped me unlock creative flow, and How to be Free channels that same liberating energy into life as a whole: how we love, work, heal, and show up every day. It includes simple rituals, helpful reflection prompts, and mindset shifts that make room for full, authentic expression. I already have a long list of friends to give this to.
