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.

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.

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.

Review: Super easy to use and calibrate - I started using the cheap ph and EC pens, and the worked okay, but I was having regular issues, and the calibration was very convoluted. In contrast, these BlueLab pens are awesome! The initial calibration was a breeze, and they have needed very little to no care other than keeping them clean. My only quibble is that the backlight on the pens times out a little on the quick side. Not a big issue, but it would be nice if there was a light button so the backlight could be turned back on. My advice to anyone getting into hydroponics or just in need of a ph and EC meeter, gust get BlueLab. Anything else is a waste of money, time, and ultimately frustration. Review: Great beginner Kit everything you need to get started. - Packaging wasen't the greatest, It got shipped with some PH adjust that I ordered and the kit it comes in was thrown in a bigger box with the the bottles and had minimal packaging around it. Dont order with anything else to assure it arrives safe. So far ive had it for a month and done 50 samples maybe. Its told me to calibrate it (with a check mark display)only a few times after i got it. It was weird that i calibrated it with PH7 then PH 4 as directed, but after calibrating with PH4 it would display the checkmark again so i would have to calibrate it with PH7 to get the check mark to go away. Im happy, this is a great kit for a beginner like me. come with a small book about hydroponics in general and what PH is all about. Manuals are very informative and instructions are very clear. One thing i dont like is the lanyard for the cap on the PH meter, its kinda awkward to hold the cap and the meter while stirring your solution mix but ive kinda figured it out, using my index finger run thru the loop at the top and the cap in my palm. Manuals make it Very Clear about letting the bulb dry out , throw it out, this is a great kit. individual testers would be double this amount, i got this kit for $147. after much shopping. ## Features - Comprehensive Monitoring Kit: The Bluelab pH and Conductivity Starter Pack is a complete solution designed specifically for growers who value precision and convenience. Whether you're a novice or a professional, this pack provides the tools you need to monitor and manage nutrient solutions with ease and accuracy. It's a comprehensive kit that simplifies the growing process, making it more efficient and effective. - User-Friendly Design: The pack includes two pens, each featuring a user-friendly interface and the ability to measure temperature in both Celsius and Fahrenheit.

Their compact and convenient design makes them perfect for on-the-go measurements, providing flexibility and convenience. - Ready-to-Use Conductivity Pen: The Conductivity Pen is ready for use straight out of the box, offering measurements in EC, CF, TDS (500 ppm), and 700 ppm scales. It comes factory calibrated, eliminating the need for any initial setup. This pen provides immediate, accurate readings, making it a reliable tool for managing nutrient solutions. - Accurate pH Pen: The pH Pen, accurate to 0.1 pH, requires a quick two-point calibration process (reference sachets included) to ensure accurate nutrient delivery to plants. It measures pH and temperature using a double-junction probe and a simple, two-point pH calibration with a 30-day reminder. This pen is designed to provide precise, reliable measurements, ensuring optimal plant health. - Reliable and Durable: These pens are specifically designed for nutrient reservoirs, making them waterproof and able to float in any solution. This makes them a reliable tool in any growing environment.

I figured that it wasn't too serious, since sometimes these things happen and it should have a warranty. In the meantime, I decided I'd order a new EC pen since I have to make sure to feed my plants properly -- they're very picky. The new pen arrived within days and after thoroughly cleaning and rinsing, as instructed to before calibration, I attempted to calibrate the new EC pen. No dice. Tried cleaning and rinsing again -- nothing. I contacted Amazon and got a replacement sent (props to Dash for getting me taken care of quickly and painlessly), and tried to clean and calibrate the NEW EC pen...to absolutely no avail. Still getting "Er" code on the display. So it seems that no matter what I do, bluelab products are simply not worth the effort to try and use and DEFINITELY not worth the cost. It's a shame, really, because I feel like I remember their products actually working when I first started using them 3 years ago or so. I will be looking for a new manufacturer for my plant feed analysis products and highly recommend that anyone reading this review does the same! Edit: I managed to get in touch with customer service and they were not happy to hear about my dissatisfaction. The representative went out of her way to set me up with new solutions to calibrate pH and EC. Sent express directly to me from the manufacturer instead of an Amazon warehouse, so they actually worked. She also called me to follow up a few days later and asked if the solutions worked or if they needed to send a new pen. The level of dedication totally changed my mind about bluelab. ## Frequently Bought Together - Bluelab PENSTP pH and Conductivity Starter Pack - Precision Nutrient Solution Management Kit with Temperature Measurement, Waterproof Pens, and Probe Care Kit - Bluelab pH 4.0 & 7.0 Calibration Solution Kit - pH Meter & pH Pen Calibration for Balanced Nutrient Solution NIST Traceable | Hydroponics, Gardening & Growing Tents (500 ml/ 16.9 Fl Oz Each) - Bluelab STSOL120 KCL Storage Solution 120ml pH Probe and Pen, Maintain Meters Used for Water, Soil, and Hydroponic System or Indoor Plant Grow White --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.nz/products/557789675-penstp-ph-and-conductivity-starter-pack-precision-nutrient-solution-management](https://www.desertcart.nz/products/557789675-penstp-ph-and-conductivity-starter-pack-precision-nutrient-solution-management) --- *Product available on Desertcart New Zealand* *Store origin: NZ* *Last updated: 2026-06-01*
