## Description

pH Pen Meter and Probe Care Kit pH with Calibration Supplies, Storage Solution & Brush, Reliable Digital Tester for pH, Temperature in Growing Solutions, Optimal Plant Health and Yield

## Features

- Reliable & Easy-to-Use: The Bluelab pH Pen is waterproof, features a backlit LCD for easy reading in any light, and automatically adjusts for temperature changes. Accurately measures pH in nutrient solution (acid or alkaline) for precise up and down adjustment with a lab-quality glass probe. The pen's double junction electrode has a longer lifespan compared to standard probes due to less contamination. It's more accurate and reliable than comparable pens, test strips, drops, and more. *Note: readings in tap, reverse osmosis (RO) or distilled water may be slow and/or unstable due to insufficient dissolved Ions (salts).
- Temperature Consistent & Durable: This hydroponics tester features ATC, providing consistent readings regardless of any temperature fluctuations. It also reminds you when calibration is due. Boasting a durable design, it's built for repeated use & is fully waterproof, even floating in solutions. With an auto-off feature and a low battery indicator, this pH pen extends battery life and alerts you when it's time for a battery replacement. The pen comes ready-to-use with a AAA battery included.
- Comprehensive Care Kit: The Bluelab Probe Care Kit pH includes everything you need to maintain your pH pen, including probe care instructions, 18 ml single-use Bluelab Solution Sachets for calibration (two each of pH 7.0, pH 4.0, KCl solutions), and three plastic cups for mixing solutions.
- Maintains Probe Integrity: The kit includes a pH Probe Cleaner and a specially designed toothbrush for cleaning the delicate pH probe, ensuring accurate readings and preventing residue build-up.
- Optimize Plant Health: The Bluelab pH Pen and Care Kit offer a complete solution for pH testing and management, helping you create the best conditions for your indoor plants or hydroponics, leading to improved plant health and greater yields. Ideal for various uses, including growing tents, swimming pools, drinking water, aquariums, fish tanks, and brewing

## Questions & Answers

**Q: Why should I choose the Bluelab pH pen over others?**
A: 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).

**Q: Other pens come with a hard carry case & calibration solutions in plastic bottles.  Yours does not.  Why is that?**
A: 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.

**Q: How does Bluelab make calibration super easy?**
A: 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.

**Q: I sometimes see a white crust built up on the end of the pen. What is this?**
A: 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.

**Q: There's a lot here about growing plants. Can I use the Bluelab pH pen for other applications?**
A: Absolutely! Our pen is a critical tool for anyone who is seeking precision and consistency in the pH of their liquid solution. Our pen is used by leading brewers, vintners, wastewater technicians, and scientists in the field, just to name a few.
