Who This Is For
- You are moving to digital testing because liquid drop kits are too subjective to read accurately under grow lights.
- You are switching to a waterproof meter because your last unit shorted out after a single drop into the reservoir.
What We Found
- The waterproof housing is a lifesaver for anyone who has ever fished a dead meter out of the bottom of a deep tank.
- We find the auto-off function saves a lot of money on AAA batteries since everyone forgets to click it off eventually.
- Digital calibration is much faster than the old screwdriver style where you spend minutes chasing the right number.
What Users Say
- Users who switched from cheap yellow pens say they stopped double-checking every reading to see if it was actually right.
- People running large reservoirs report that the lanyard keeps the meter from getting lost in the mix during busy days.

FAQs
How often should I calibrate the PH-200?
For best results, we recommend calibrating your meter at least once a month or if you notice inconsistent readings. If you use it daily, weekly calibration is ideal.
Is the pH sensor replaceable?
Yes, the PH-200 features a replaceable glass sensor. This allows you to keep the meter for years by simply swapping out the electrode when it reaches the end of its lifespan.
Can I use this for both soil and water?
This meter is designed for liquid testing. To test soil pH, you should create a slurry of soil and distilled water to get an accurate reading.
Does this meter measure TDS or EC?
No, the PH-200 is dedicated to pH and temperature. For TDS and EC, we recommend the HM Digital Pro COM-100.
Is the unit completely waterproof?
Yes, it features an IP-67 waterproof rating, meaning it is fully submersible and will float if dropped into a reservoir or pool.
