P160 Pro Combo Pen – 5-in-1 Digital Meter for pH, EC, TDS, PPM & Temp

The P160 Pro Combo Pen is the definitive tool for the grower who refuses to leave their harvest to chance, offering five essential measurements in a single, robust device. It instantly analyzes pH, EC, TDS, PPM, and temperature, giving you total control over your nutrient solution to guarantee explosive growth and problem-free flowering.

Are you feeding your plants blindly?

You probably invest a lot of money in top-tier nutrients and genetics, but if you pour them into water with the wrong pH or excessive conductivity, you are wasting your resources. Many growers rely on intuition or cheap, uncalibrated tools, not realizing that a simple imbalance is blocking the roots from absorbing food.

There is nothing more frustrating than seeing your plants turn yellow, develop burnt tips, or stop growing despite your best efforts. This "nutrient lockout" is the silent killer of yields. Plus, juggling three different meters or messing around with color-changing drops is a hassle that wastes your valuable time and leaves you with stained hands and uncertain results.

The P160 Pro Combo Pen eliminates this uncertainty immediately. By simply dipping the probe, you get a complete X-ray of your water quality, allowing you to adjust the parameters with surgical precision so your plants can absorb 100% of the cannabis fertilizers you provide.

Why this product improves what you already have

If you are still using reactive drops or basic analog meters, the leap to the P160 Pro is like switching from a map to a GPS. The main difference is the integration and speed. You no longer need to dip one pen for pH, clean it, and grab another for EC. This device gives you all the data on one screen, automatically compensating for temperature (ATC), which is often the cause of false readings in cheaper devices.

Furthermore, its robust and waterproof design (IP67) is built for the reality of a grow room. It doesn't matter if it accidentally falls into the tank; it floats and keeps working. It offers the professional reliability required for high-performance Hydroponic and Aeroponic Systems, where precision is the difference between a record harvest and a total loss.

Key features you’ll notice from the very first use

• 5-in-1 Versatility: Measures pH, Electrical Conductivity (EC), TDS, PPM, and Temperature simultaneously.
• Digital Precision: Forget about interpreting colors; get exact numbers to fine-tune your nutrient mix.
• Waterproof (IP67): Designed to survive splashes and accidental drops in the reservoir.
• Automatic Calibration: Digital calibration makes maintenance easier and ensures your data is always real.
• Replaceable Electrode: Extends the life of the device; if the probe wears out, you don't have to buy a whole new pen.
• Auto-off function: Saves battery life so it's ready when you need it most.

Who this product is especially interesting for

The P160 Pro is a must-have for any grower who takes their hobby or profession seriously, but it is specifically designed for:

• Hydroponic Growers: In hydro, water is everything. You need constant and precise monitoring of EC and pH to prevent root rot and pH fluctuations.
• Coco and Soil Growers: Perfect for measuring the "runoff" water and understanding if salts are building up in the substrate.
• Tech-Savvy Growers: If you love data and control, this tool gives you the professional metrics you crave.

How to integrate it into your routine without overcomplicating things

Using it is as simple as dipping and reading. When preparing your nutrient mix, add your fertilizers, stir, and then use the P160 Pro to check the EC. Once the strength is right, check the pH and adjust it up or down. That's it.

To keep it precise, simply rinse the probe with tap water after each use and put a few drops of storage solution (KCL) in the cap. This small gesture ensures that your measuring instruments remain accurate for years.

Frequently Asked Questions

Does it come calibrated from the factory?

Yes, the P160 Pro comes factory calibrated and ready to use. However, we recommend recalibrating it periodically (once a month or before a critical measurement) to maintain maximum precision.

Is it difficult to change the batteries?

Not at all. It uses standard batteries that are easy to find and replace. Plus, the auto-off indicator helps extend their life significantly.

Can I measure the temperature of the water with this?

Yes, and it is a crucial feature. The temperature of the water affects the amount of oxygen available to the roots. This pen tells you if your water is too hot (risk of fungi) or too cold (shock to the roots).

Personal Experience of Pevgrow’s CEO (Alan)

I remember when I started growing, I had a drawer full of different meters—one for pH, a separate stick for EC, and a thermometer floating in the tank. It was a mess, and half the time one of them was out of batteries. Switching to a combo pen like the P160 Pro changed my workflow completely. The peace of mind of knowing that the reading is temperature-compensated is priceless. If you are serious about getting dense, heavy buds, you need to stop guessing what's in your water. This tool is one of those investments that pays for itself with the first harvest you save from a pH imbalance.
