Bluelab PENSTP pH and Conductivity Starter Pack - Precision Nutrient Solution Management Kit with Temperature Measurement, Waterproof Pens, and Probe Care Kit

Bluelab PENSTP pH and Conductivity Starter Pack - Precision Nutrient Solution Management Kit with Temperature Measurement, Waterproof Pens, and Probe Care Kit

Q: What is included in the Bluelab pH & Conductivity Starter Pack?

The pack includes a Bluelab pH Pen, a Bluelab Conductivity Pen, and everything needed to calibrate, clean & maintain them both. This includes KCl Storage Solution, pH Calibration Solutions, 2.77EC Standard Solution, probe cleaners & probe brushes.

Q: Why should I choose Bluelab as opposed to other pH & conductivity measuring companies?

Simply put, the quality of our probes. They are highly accurate & are fast to a stable reading. They are very robust & durable. And, as growers ourselves who use these tools every day, we've built them with a handful of thoughtful design touches.

Q: Can you give me some examples of those design touches you mentioned?

The ring at the top of each device (makes it so much easier to hold while taking readings). The storage cap on the pH Pen, deliberately designed to keep the probe well hydrated. The backlit screen. The ease in changing units. Just to name a few.

Q: I sometimes see a white crust built up on the end of the pH 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 a white crust on your probe. Simply rinse this away under water.

Q: There's a lot here about growing plants. Can I use Bluelab meters for other applications?

Absolutely! Our pens are critical tools for anyone who is seeking precision and consistency in the pH of their liquid solution. Our pens are used by leading brewers, vintners, wastewater technicians, and scientists in the field, just to name a few.

Reviews

T**N

Best on the market for exotic plants and also for my aquarium.

Bought for my Venus fly trap and other carnivorous plants as well as cactus plants. Very very accurate and nice backlight displays. Temperature measurements are spot on. Calibration is so easy. Make sure to store the ph probe in the right type of solution.
