TDS meter pen dipped in a glass of water showing a reading of 780 ppm — typical Cabo water. Clean, simple product shot.
Digital TDS/Temperature Meter
Medidor Digital de TDS/Temperatura
Know your water's mineral content in 3 seconds
Pen-style TDS meter that measures Total Dissolved Solids (mineral content) and temperature instantly. Essential for tracking hardness, comparing pipa sources, and verifying treatment system performance. Includes carrying case and calibration solution. Note: TDS measures minerals, not safety — for microbial testing, see our Water Testing Service.

What It Tells You (and What It Doesn’t)
A TDS meter measures the total mineral content of your water — primarily calcium and magnesium in Cabo. It’s the fastest way to check if your water is hard (it is), compare between pipa deliveries, and verify that your RO system is working.
What it does NOT measure: bacteria, viruses, or microbial safety. A reading of 50 ppm doesn’t mean the water is safe to drink — and a reading of 900 ppm doesn’t mean it’s dangerous. For safety testing, pair this with our Water Testing Service or a chlorine test kit.
