Our Testing Experience

First Impressions

When I first got the Hofun 3 in 1 TDS Meter, I was excited to try it out because I wanted a simple way to check my tap water quality. The device felt light and easy to hold, and the big backlit LCD screen made it super clear to read the numbers, even in my dim kitchen. Turning it on was quick, and I liked that I didn’t have to do much—just dip it in the water and wait a few seconds for the results. The auto-lock function was a nice surprise too, as it kept the reading on the screen without me holding the meter steady.

Daily Use

Using the meter every day became part of my routine, especially for testing water from different sources like the well and my aquarium. It was fast and simple—I just stirred the water gently, dipped the meter, and instantly got the reading. The HOLD button was handy when I wanted to note down the numbers without rushing. I also tested water from my RO system and swimming pool, and the wide range of measurement made it easy to trust the results. It saved me time and gave me peace of mind about the water I use daily.

Key Features in Action

The most useful feature for me was the premium titanium alloy probe. It felt sturdy and gave very quick readings, which meant no waiting around. I also appreciated the energy-saving auto shut-off; I never had to worry about forgetting to turn it off. The temperature meter was a bonus, letting me check water temperature alongside TDS and conductivity without needing another tool. Overall, the clear display and easy one-button operation made it perfect for anyone, even if you’re not a tech expert.

Long-Term Performance

After using the Hofun meter for a few weeks, I’m happy to say it has been reliable and consistent. The readings stayed accurate, and the device showed no signs of wear despite regular use. The small size made it easy to store in my kitchen drawer, ready whenever I needed it. It truly felt like a handy, trustworthy tool for monitoring water quality at home, and I would recommend it to anyone who cares about the safety of their drinking water or needs to test water for hobbies like aquariums or hydroponics.
