Rapitest Meditor Universal is a multifunctional meter that allows you to monitor soil pH, soil moisture and light intensity.

The pH of the soil affects how well plants use the common nutrients available in the soil. These nutrients are the building blocks the plant requires for healthy growth. Optimal growth can not be achieved with inadequate or incorrect amounts of light. And even if these two key cultivation conditions are ideal, your garden will not flourish if it is unspoiled or overcrowded.

INSTRUCTIONS FOR USE:

Strike the tester in the soil and slide the test selection switch.

Note: DO NOT use with liquids.

The Fertometer is an EC meter that measures the level of electrical conductivity in the soil, thus measuring the amount of salt in the substrate.

With this device, you can easily avoid mistakes such as pacing or shortage. The Fertometer works on the same principle as the plant. Like the plant's roots, it absorbs nutrients from the soil.
 
By measuring the quantity of the substances taken, it can be determined whether there is enough nutrients remaining in the substrate. These resorbable nutrients are called ions and consist mainly of nitrogen, the main nutrient for plants during vegetation.

BlueLab pH Soil Pen is the most convenient solution for measuring soil pH and temperature!

Bluelab pH soil pen provides pH and temperature reading of soils and growing medium to make sure that the right nutrients will be delivered to your plants.
 
In soils or growth media, the pH has a strong influence on the presence of microorganisms in the soil. With this tester you can carefully monitor and adjust the pH levels, thus optimizing plant health and productivity!
Besides soil and soil media, the tester can also measure nutrient solutions.
 

• - Direct pH and temperature measurements in soils / solutions
• - Illuminated LCD display
• - Continuous reading function
• - Built-in probe storage cap
• - Success Rate Calibration Indicator
• - Low battery indicator
• - Fully waterproof
• - Auto-off function
• - Selectable temperature units
• - Automatic temperature compensation
• - Included 1 x AAA alkaline batteries

ADWA AD 100 is an Electronic pH Tester

 
Remove the cap. If white crystals are formed, they will break down in the process. To improve the performance of the appliance, saturate the tester tip in pH 7 buffer solution for ten minutes.
 
Calibration: Calibrate this tester once a week or at any time if you suspect there is a reporting problem. The Adwa pH Testers can be calibrated at 4.7 and 10 pH values.
ALWAYS calibrate with pH 7 first!
 

• Put the tester tip in pH 7 buffer solution and press ON / OFF.
• Press CAL, 7.0 and then the pH will begin to blink on the screen. When the pH label stops blinking, the reading is stabilized.
• Press READ; 4.0 pH will blink on the screen.
• Rinse the tip of the tester with distilled or iodized water.
• Put the tip of the tester into pH 4 buffer solution (for acidic values) or pH 10 buffer, "10.0" and "4.0" will start to blink (for bases)
• When the pH stops flashing, the reading is stabilized.
• Press READ. Calibration is complete.

 
Work:
 
1) Remove the protective cover.
 
2) Press ON / OFF to turn on the appliance and place the tester tip in the sample to be measured. Mix the sample and record the value when the figures stabilize.
 
3) Press ON / OFF to turn off the tester.
 
ADWA TESTERS MAY BE LOADED TO LIGHT CRANIAL SCREEN
 
Support:
 
The sensor should always be wet. This is done by dropping a few drops of a pH 4 solution into the tester cap. Rinse the electrode with running water after each measurement.
 
WARNING: DO NOT USE STORED OR DISINFECTED STORAGE WATER
