Bluelab®
pH Pen
The Bluelab® Portable pH Pen is the latest innovation from Bluelab that will set the new standard for hand held pH meters and is the ultimate in convenience for measuring pH in nutrient solutions or any other liquid.
Hydroponic growing lets you give the best care possible to your plants. The quality of that care is in your control.
The Bluelab® pH Pen provides a compact, quick and handy way to manage the success of your crops to ensure maximum uptake of nutrients. Teamed with the Bluelab® ppm Pen, you have a handy, convenient and accurate system for ensuring optimum plant growth and health.
The Bluelab® pH Pen has been specifically developed as an affordable and effective option for hobby or small scale growers. Measuring pH is vital to the success of your crop because plants, like people, eat food.
Plants get their nutrition from minerals but the minerals they need are only available if certain conditions are right. A key factor that affects food uptake by plants is whether their nutrient solution is acid or alkaline. We measure this in pH.
The clever little Bluelab® pH Pen ensures you maintain the optimum pH reading that allows nutrients to be available to your plants.
Once you have measured the pH using the Bluelab® pH Pen and know your plants can get at the food, you then need to measure how much food is available. This is referred to as conductivity and is measured by using the Bluelab® ppm Pen, available here. |

Bluelab®
Portable pH Meter
The Bluelab® Portable pH Meter will give you the pH measurement of a solution. Suitable applications are in hydroponics, horticulture, agriculture, aquatics, waste water, swimming pool and spa...anywhere that a pH measurement is required! Simply place the removable pH probe into the solution and the pH reading will be displayed on the screen. |
|
|
|
|
|
|
Since the meter is portable and does not require an external power supply to operate, it can be used anywhere and anytime to help you manage your crops daily pH requirements.
The Bluelab® Portable pH Meter is super easy to calibrate simply by using the convenient push buttons on the face of the meter along with fresh Bluelab calibration solutions.
pH test strips are an old fashioned method of measuring pH and are inaccurate and inefficient.
In a swimming pool, the chemicals used can bleach the test strips and provide a less than perfect reading as a result!
In hydroponics, a pH reading is generally required after every addition of nutrient and once or twice a day. As the plants take up the nutrient, the pH level normally rises and thus needs adjusting. As the water evaporates the pH value of the nutrient solution will drop. These situations are controlled more effectively if you take regular pH readings of your nutrient solution. Using a Bluelab® Portable pH Meter is faster, easier, far less cumbersome and more cost effective than pH test strips!
As the Bluelab® Portable pH Meter is lightweight and portable and does not need a power supply to operate, it can be used anywhere and anytime.
To take a pH reading of your solution, simply place the pH probe tip into the solution, push any button to turn the unit on and after a few minutes a stablised reading will be displayed on the large 13mm (1/2 inch) tall digital display.
pH measuring instruments need to be calibrated to ensure the reading remains accurate. The Bluelab® Portable pH Meter is so easy to calibrate by using the push buttons on the meter and fresh pH 7.0 and pH 4.0 calibration solutions. Bluelab® has made it even easier for you by placing the calibration instructions directly on the back label of the meter! Handy!
It is powered by two (2) AAA alkaline batteries and has a low battery indicator to let you know when they will require replacing. The meter also turns itself off after a period of inactivity to save battery power.
The included premium quality pH probe connects to the Bluelab® Portable pH Meter by a BNC (bayonet Neill-Concelman) connector so the probe is easily removed for storage or when replacing.
The Bluelab® Portable pH Meter can accurately measure pH between the full range of 1 to 14 pH. Because the Bluelab® Portable pH Meter has such a large range, it is crucial that calibration be made between two points; pH 7.0 and pH 4.0.
Many cheap meters have a similar range but state that only one point calibration is required....be very skeptical as to the accuracy of these products!
Included with your Bluelab® Portable pH Meter is a premium commercial quality pH probe with a 2 meter (6 1/2 feet) cable length; pH 7.0 20ml single use calibration solution sachet; pH 4.0 20ml single use calibration solution sachet; two (2) AAA alkaline batteries; guarantee card (or you can register your guarantee on-line); instruction manual; and a maintenance record card.
The Bluelab® Portable pH Meter can also be used to test the pH of soil with the optional Soil pH Probe available below.
5 Year Bluelab® Guarantee on Bluelab® pH Meter
6 Month Bluelab® Guarantee on Bluelab® pH Probe
These meters have proven themselves in the horticultural market for years. The guarantee is Bluelab's badge of proof - reliability and accuracy! Any pH measuring instrument is only as accurate as the probe is clean! Be sure to also purchase a Bluelab® pH Cleaning & Calibration Kit below! Replacement Bluelab® pH Probe also available.

Soil pH Probe
This non-refillable soil pH probe is used to measure the pH levels of soil or media of cropping, pasture, containerized plants, home gardens, propagation culture...anywhere that the soils pH requires testing. |
|
|
|
|
|
|
This probe can be used for direct pH measurements in soils. The soil probe is supplied with a 'Dibber' - the green spear pictured above. The 'dibber' is inserted into the media/soil prior to inserting the pH probe to ensure no damage occurs to the probe tip from coarse soil particles, stones etc.
Soil pH can also be measured by taking soil solution samples. The instruction sheet supplied will provide guidance for taking both methods of soil pH measurements.
The Bluelab® Soil pH Probe Replacement is fully waterproof; features a quality BNC connection with a tough polypropylene barrel; heavy duty thick wall glass stem; and a non-refillable gel junction. Includes dibber / auger. Total probe length is 2 meters.
The Bluelab® Soil pH Probe can be attached to the Bluelab® pH Meter and Bluelab Combo Meter, or can be purchased as complete as a Bluelab Soil pH Meter. 6-month manufacturers warranty. |

Bluelab® pH
Cleaning & Calibration Kit
Any pH measuring instrument is only as accurate as the probe is clean!
The probe surface is where the instrument takes the reading of the solution. That information is then sent back to the electronic brain of the instrument. |
|
|
|
|
|
|
A calculation is then done by the micro computer and your reading is then displayed, accurately, one hopes. However, if the information sent back from the probe is inaccurate due to probe surface contamination then the reading will be inaccurate. Garbage in, garbage out.
Cleaning the probes is a very easy task and prolongs the life of the probes.
The Bluelab® Cleaning and Calibration Kit contains everything you need to keep your meter properly calibrated and your probe clean!
The Bluelab® pH Cleaning and Calibration Kit includes full color laminated directions; pH 4.0 standard reference solution (250ml); pH 7.0 standard reference solution (250ml); De-canter vessels; Probe cleaner; and Cleaning brush. |

Bluelab®
pH Calibration Solutions
Bluelab® pH Calibration Solutions are a very necessary part of a growers toolbox. They are required for the calibration and checking of Bluelab® meters, monitors, and controllers. Bluelab® Calibration Solutions are manufactured specific to the calibration process and referenced to high class laboratory standards. |
|
|
|
|
|
|
Bluelab® pH Calibration Solutions should be stored in a cool place out of direct sun and heat. Please keep out of reach of children. They should be stored with the lids securely tightened. Not replacing the lid after use will result in evaporation which causes the salt content in the solution to rise decreasing the validity of the solution.
Contamination between solutions can easily occur, which will affect the validity of the calibration. Bluelab® recommends that the solutions are de-cantered into a smaller vessel and the contents discarded when the calibration process has been completed.
Bluelab® pH Calibration Solutions are available in 4.0 and 7.0 calibration points in 250 milliliter (8.45 U.S. fluid ounce) and 500 milliliter (16.9 U.S. fluid ounce) bottles. Meter and decanter shown not included. |
