The DigiStick replaces the EC Dipstick as the new flagship PPM meter from Control Wizard Products. The lighted display is large and easy to read. There are no mistakes when the temperature compensating microchip quickly senses the electro conductivity of the nutrient solution or water sample and automatically freezes the displayed reading. PPM, EC and CF scales are easily accessed by easy to read buttons. Cutting edge electronic circuitry keeps the meter in calibration for extended periods of time. The DigiStick is waterproof from the electrode up to the display, water resistant from the display to the battery cap. Uses a common 9-volt alkaline battery for power. Use 1382 ppm (500 ppm – 1 EC) calibration buffer. Affordable quality for long-term customer satisfaction.

The Checker supplies you with fast and accurate readings from 0.00 to 14.00 pH with a resolution of 0.01 pH.

This compact tester features a large easy-to-read LCD and a simple to perform 2-point calibration.

The Checker is fast, accurate, lightweight and with 3000 hours of battery life, you don’t have to worry about frequent battery replacement.

The Primo pocket TDS meter gives a direct digital readout in mg/L (1mg/L is the same as 1ppm), on a clear LCD display and is ideal for water testing.

The meter has a single button located on the top of the meter, which is pressed once to switch on and ready for use. Battery life is an impressive 200 hours, which is further enhanced by the automatic switch-off after 5 minutes of inactivity.

To calibrate the meter, simply press and hold the button for a few seconds and the Primo will automatically enter calibration mode. Simply place the Primo sensor in the calibration solution and within seconds the meter will automatically recognize the value of the solution and self-calibrate – no further pressing of buttons required. Primo uses calibration solution with a value of 1382ppm/mg per L which is Hanna part number HI-70032P.

Stainless steel probes deliver fast and accurate readings with ten times better resolution.

Comes with protective case and calibration solution.

Microprocessor based waterproof pH tester with 1500 hour battery life, very accurate manual calibration and protective case with calibration solution.

The Nutradip Tri-Meter combines the technology of the pH
#8200;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.

Same as pH1 but has temperature compensation. The temperature of the water will not throw off the reading.

Optimize nutrient strength during growth, flowering, and fruiting.

Same reliable waterproof dustproof housing as pHTestr.

Ideal for Student, Hydroponics, and Hobbyist use!

Economical, pocket sized meter is perfect for less demanding applications.

Easy to use; push-button calibration with auto buffer recognition.

Includes transparent electrode cover/sample cup, Push-button calibration, HOLD function, and error messages.

Fill a test-tube halfway with nutrient, add a few drops of pH Test Indicator, and observe the coloration of the liquid in the test vial. Use 3 drops per 5mL of solution.

Gardeners can think deep thoughts about their soil thanks to Control Wizard Soil pH Moist Meters! They just push the electrode probe into an area of soil they’d like to test, and it automatically displays its pH. If moisture levels are a concern, they’re a mere button-push away. This helpful tool doesn’t need batteries or calibration.
