Spider Farmer 5-in-1 Hydroponic pH Meter Kit - pH/EC/TDS/Temp/Salinity

One meter to keep on top of your nutrient solution. The Spider Farmer 5-in-1 Hydroponic pH Meter Kit reads pH, EC, TDS, temperature and salinity from a single probe, so you can check where your reservoir is sitting and adjust before your plants feel it.

Why growers choose the Spider Farmer 5-in-1 pH Meter

• Five readings, one tool: measures pH, EC, TDS, temperature and salinity, covering the numbers that matter for nutrient uptake in a single device.
• pH and TDS together: both values show on the one screen, so you can read your solution at a glance rather than switching modes.
• Accurate, stable readings: a high-sensitivity electrode holds to ±0.05 pH, helping you recognise drift before it causes lock-out or wasted nutrient.
• Built for wet work: IP67 waterproof and dustproof sealing stands up to spills and reservoir dunking.
• Rechargeable and ready: the built-in 600mAh lithium battery charges over USB Type-C, lasts around 300 charge cycles and holds up to six months on standby.
