The Spider Farmer SF-PH-Meter 5-in-1 Hydroponic Meter Kit is a professional-grade digital testing tool designed to help growers accurately monitor and maintain optimal nutrient conditions in hydroponic systems, reservoirs, coco setups, and soil feeding programs.

This advanced 5-in-1 tester accurately measures:

• pH
• EC (Electrical Conductivity)
• TDS (Total Dissolved Solids)
• Temperature
• Salinity

Using a high-sensitivity electrode sensor with approximately ±0.05 pH accuracy, the meter provides fast and stable readings to help growers prevent nutrient lockout, overfeeding, and pH instability.

The large LCD display shows readings clearly and allows growers to monitor nutrient solution conditions quickly and efficiently. Designed specifically for hydroponics and indoor cultivation, the meter features an IP67 waterproof and dustproof design, making it suitable for humid grow room environments.

Powered by a rechargeable 600mAh lithium battery, the unit supports USB-C charging and offers long standby performance for convenient everyday use.

The included calibration powders help ensure long-term accuracy and reliable nutrient management.
