BlueLab ph soil pen

The Bluelab Soil pH Pen is an accurate way to measure soil pH and temperature directly in the root zone of your plants. If necessary, the soil pH pen can be used in nutrient solutions .

Simply poke a hole in the soil with the storage cap and insert the probe to get constant pH and temperature measurements.

pH 0.1 ±; Temperature: ± 1 ° C ± 2 ° F
- Calibration: Two points (pH 7.0 and pH 4.0 or pH 10.0)
- Automatic temperature compensation: Yes
- Operating environment: 0-50°C, 32-122°F
- Power source: 1 x AAA alkaline batteries
- Certificates: CE; FCC; WEEE

How to use:
**Important : You must calibrate your pH pen before first use .

• Use the storage cap to make a hole in the soil. Place as deep as the roots of your plant.
• Carefully remove the storage cap by first unscrewing the cap and gently pulling to remove the probe. The cap contains KCl solution , so be careful not to spill the liquid. The formation of a salt crust around the probe is normal.
• Turn on the pen and insert the probe into the opening. Make sure the tip of the probe is in contact with the soil at the end of the hole. The display will stabilize and give you pH and temperature readings.
• Rinse after use to remove nutrient or dirt build-up and replace cap for storage

How to calibrate:
**Calibrate after each cleaning and at least once a month.

• Turn on the pH pen.
• Calibrate to pH 7 by placing the probe tip in a pH 7 solution . Wait for the reading to stabilize between pH 6.6 - pH 7.5 .
• Long press the Cal button until CAL is displayed. Release the button. The calibration sequence will begin flashing "0" on the display in sequence. Once “0000” stops flashing, the sequence is complete. Rinse the probe tip in fresh tap water.
• Repeat with pH 4 solution.
• A checkmark will confirm successful calibration.

Hydrate
** Keep the probe hydrated with Bluelab KCl solution. Without proper hydration, readings may be inaccurate and the probe may break.

1. Add enough KCl storage solution to submerge the tip of the probe in a plastic cup and allow to soak for 24 hours.
2. Make sure there are a few drops of KCl solution in the storage cap
