6-in-1 Precision Engineering & Rapid Readings

The Hydroponic Meter PRO is a powerful instrument that measures six vital parameters: pH (acidity), EC (electrical conductivity), TDS (total dissolved solids), salinity (salt content), alkalinity, and temperature. The highly reactive sensor probe with a **lithium-glass membrane** delivers near-instant pH results with pinpoint ±0.01 accuracy. This allows you to fine-tune your nutrient water to the smallest detail for maximum yield.

Rugged Build & IP-67 Protection

This PRO meter is built for heavy-duty use in humid grow rooms and greenhouses. Featuring an IP-67 certification, the device is fully waterproof, dustproof, and sand-resistant, and can withstand high temperatures. A standout feature of this model is the interchangeable sensor probe; instead of purchasing an entirely new meter, simply install a replacement probe to significantly extend the service life of your device without sacrificing accuracy.

Complete Lab-Standard Calibration Kit

The kit comes as a complete laboratory package. The set includes 4.00 pH, 7.00 pH, 12.88 mS, and 1413 µS calibration solutions to ensure consistent precision for all your readings. Additionally, the **3M KCL solution** is included to provide ideal storage conditions for the sensor. This prevents the probe from drying out and guarantees a lightning-fast response time for every measurement.
