Bluelab pH Pen - ± 0.1 pH Accurate - Durable Double Junction Probe
5 sold in last 24 hours
- Perfect pH control for various media - ph meter for water hydroponics can be used for growing tents, swimming pools, drinking water, aquariums, fish tanks, and brewing. Our pH meter provides a quick and handy way to manage the success of your crops. Helps you ensure that pH and temperature are always in the optimal range for maximum uptake of nutrients. *Note: readings in tap, reverse osmosis (RO) or distilled water may be slow and/or unstable due to insufficient dissolved Ions (salts).
- Easy calibration - Set up our digital pH meter with a two-point calibration process. Calibrate the handheld meter before first use. Each digital pH meter for soil and water comes with a 30-day calibration indicator that can be viewed on a backlit LCD display. The kit includes one 20-ml sachet of each pH7, pH4, and KCl for initial hydration and calibration.
- Get accurate readings with a double-junction probe. Unlike glass bulbs, the double-junction probe minimizes contamination. Hence, it helps in improving precise readings and has a longer lifespan. This pH pen has automatic temperature compensation for an accurate temperature. Our pH meter for water hydroponics will take measurements in increments of 0.1 pH.

Select a product to estimate shipping.Why should I choose the Bluelab pH pen over others?
The probe quality. Highly accurate, compensates for temp & is fast to a stable reading. It's a double junction probe, so it's durable. And it's full of thoughtful touches (the ring on top, the storage cap, the calibration indicator to name a few).
Other pens come with a hard carry case & calibration solutions in plastic bottles. Yours does not. Why is that?
Great question. We have made the deliberate choice to make our packaging as sustainable as possible. To that end, our packaging is all fully recyclable, with no hard plastics or styrofoam inserts.
How does Bluelab make calibration super easy?
Calibrating is an easy & fast process! Each pen includes calibration solutions & clear instructions. A check mark appears when the pen is calibrated. When the pen loses calibration, the check mark disappears, informing you it's time to recalibrate.
I sometimes see a white crust built up on the end of the pen. What is this?
This is very common in pH meters & is nothing to worry about. The storage solution used to hydrate your pen (and extend its longevity) is potassium salt, which sometimes dries as a white crust on your probe. Simply rinse this away under water.
Can I use the pH Pen to measure the pH of tap water, distilled water, or reverse-osmosis water?
No. For distilled & RO water there aren't enough dissolved ions (salts) for a stable pH reading. For tap water, w/o sufficient dissolved minerals, the answer is also no. Adding a few drops of KCL storage solution may work to enable a stable reading.
