Hydrocork Hydroponics & Wine Making Supplies

Gardeners can conveniently test their moisture, light, and pH levels with the handy ActiveAir 3-Way Meter. Moisture readings register on a scale of 0 (dry) to 10 (moist), light readings range from 0 (low light) to 2000 (very strong light), and pH readings between pH 0 (acidic) and pH 10 (basic) are represented. The durable, easy-to-read tester is suitable for indoors or out and needs no batteries to operate.

Delivers easy and accurate readings of your water temperature. The gauge floats and has a pressure sensitive backing for easy mounting. It features readings in both Celsius and Fahrenheit, as well as clear markings that delineate ideal nutrient temperature.

OAKTON's new EcoTestr is economical and easy to use. With its crystal clear, ergonomically designed display, you can easily view measurements at a glance.
Each rugged tester has waterproof and dustproof housing for use in dirty and damp field conditions. Simply dip and read-the orientation of the display means there's no need to turn your head or tilt the tester
Single-junction electrode is well-suited for general purpose applications. Recessed bulb with bulb guard protects against breakage
One point calibration with auto-buffer recognition for quick calibrations. Hold function locks in measured value. Auto-off function preserves batteries.

The Nutradip pH meter will continuously measure the acidity or alkalinity level of your nutrient solution, a critical factor in successful hydroponic growing. The maintenance of proper pH levels in soilless gardening is critical to plant health and yield. An imbalanced pH level in the nutrient solution can "lock out" nutrients and cause plant deficiencies when the pH is too low (more acidic). Alternately, nutrient will become trapped and over-fertilize the plant(s) when the alkalinity is too high.

The Nutradip Nutrient (TDS) meter will continuously measure the concentration of the Total Dissolved Solids (TDS) or nutrient levels in the growing solution being provided to the plants. It will assist in ensuring optimum growth in your hydroponic operation. The critical TDS measurement of your nutrient solution can be presented as parts per million (TDS meter) or as the electrical conductivity (EC meter) of the nutrient solution.

The Nutradip Tri-Meter combines the technology of the pH and TDS meters and addresses an additional key factor in hydroponic growing, the temperature. Temperature in a nutrient solution is often wrongly overlooked. The temperature variance in a growing operation can significantly restrict the growth and yield of the plant(s).
With no effort at all, reliable, continuous reading of TDS, pH, and temperature can simultaneously be monitored and correct levels can easily and reliably be maintained.
