Bluelab pH pen - compact, easy and convenient to use, the best solution for measuring pH.

The Bluelab pH Pen is a durable, compact and accurate pH and temperature pen for use in nutrient solution. Use the pH pen to quickly and accurately tell if your solution is too acidic or alkaline, or too hot or cold. Designed for everyday use, the Bluelab pH Pen helps you keep your plants in the optimal pH and temperature range so your plants can thrive.

Care Tips:

Clean and calibrate your probes monthly to maintain probe accuracy.
Always store the pH probe in the storage cap with enough KCl (potassium chloride) storage solution to cover the tip of the probe. The probe will be damaged if left dry. Read more about KCl Storage Solution.
The glass tube can be easily damaged. Be careful not to hit the glass.
Do not immerse in oils, proteins, or suspended solids, which will leave a coating on the glass flask.
Never store or soak the pH probe in RO, distilled or deionized water.

The Bluelab EC pen is the latest innovation in handheld EC meters and is the ultimate solution when it comes to EC measurement.

Measure pH, conductivity and temperature on the go. The Bluelab Combo Meter provides ultimate convenience by taking care of all three fundamentals of nutrient absorption simultaneously.

Not only that, but this multi-parameter meter and its probes feature a brilliantly simple design. The Bluelab pH probe is easy to use, clean and calibrate; when the time comes, it's also easy to replace. Similarly, the Bluelab Conductivity Probe has straightforward functionality that does not require additional calibration.
 

How to use the Bluelab EC pen:

• The conductivity pen comes with a battery and is ready to use out of the box.
• The pen is factory calibrated.
• Press the power button to turn on the Bluelab Conductivity Pen.
• To turn off the pen, press and hold the power button until OFF is displayed.
• The pen will automatically turn off after 4 minutes to conserve battery power.
• Place the probe tip into your nutrient solution and wait for the reading to stabilize.
• Rinse under running tap water after use.

The Bluelab Truncheon Meter is a robust and reliable everyday tool for measuring the concentration of nutrients in solution. With Truncheon, you'll ensure your plants get the nutrients they need for superior plant health.

Truncheon is factory calibrated with no moving parts or switches. Simply dip the probe into your feed tank and take the reading shown on the LED display.

Characteristics:

• Blue light display
• No calibration required
• EC, CF and ppm 500 and ppm 700 scales
• Fully waterproof
• Automatic on/off function

How to take your first measurement:

1. Remove the meter from the packaging.
2. Dip the probe head into your solution.
3. Wait about 10 seconds for the thermistor to reach the temperature of the solution.
4. Read the measurement indicated by the flashing LEDs. If the flashing lights alternate between two numbers, the measurement is the value between those two numbers. For example, if the lights alternate from 0.8EC and 1.0EC, the reading is 0.9EC.
5. Truncheon will turn off after about 10 seconds. If additional measurements are to be taken, remove the stick from the solution, wait a few seconds and reinsert it. It will turn on again.
6. We recommend that the probe be cleaned and accuracy checked in Bluelab 2.77 EC Solution once a month.

Note: For low or high temperatures, it may take 1-2 minutes for the probe to reach solution temperature. Try placing the probe in an area where there is strong movement of the solution, or stir the solution with the probe.

Tip: In addition to being used to measure nutrient levels, the Truncheon Meter can also be used to stir nutrients into your solution.

Bluelab soil pH 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.

Features:

• Selectable units for °C and °F
• Fully waterproof
• LCD display with backlight
• Read hold function
• Storage cap
• Automatic shut-off function

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 build-up or dirt 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 .
