YINMIK YK-E03 EC/PPM/CF/Temp Meter 35cm Wand 12 Pack

Hydroponic Nutrient Meter 12 Pack

The YINMIK YK-E03 pack supplies twelve truncheon-style meters for growers who manage multiple reservoirs. Each unit measures EC, PPM 500, PPM 700, CF and temperature in a single wand. The 35 cm probe reaches deep tanks while the LED indicator shows whether the solution sits in the target range. A one-button hold function locks the reading for easy recording.

Wand Design and Daily Use

The 14.2 inch wand lets you stir AB nutrient blends and test conductivity at the same time without switching tools. Calibration uses the included 1413 µS/cm reference solution, and the display resolves to 0.01 mS/cm or 1 ppm. Before mixing, the meter checks base water to confirm it sits below 80 ppm, helping prevent nutrient lock-out. The package includes a manual for quick setup.

Measurement Ranges and Operation

EC spans 0.00 to 9.90 mS/cm, while PPM 500 covers 0 to 4990 ppm and PPM 700 covers 0 to 6990 ppm. CF reads 0.0 to 99.0 and temperature reports 32.0 to 122.0 °F (0.0 to 50.0 °C). The device draws minimal power during normal spot checks, runs silently and produces no heat that could affect the reservoir. It is not suited for continuous inline monitoring or automated dosing systems.
