Aquamaster Combo Pen P160 Pro – pH, EC, TDS and Temperature Meter with Replaceable Electrode

Frequently asked questions

• What does the Combo Pen P160 Pro measure?

  In a single pocket device it measures pH, EC, TDS, PPM and the temperature of the nutrient solution. With those five parameters you cover all of your reservoir's daily monitoring. It also comes factory-calibrated, so you can start measuring right away.

• Why sell a model from the previous range?

  For a very practical reason: this meter does have a replacement electrode available, the Combo pH+EC+T electrode for the P160 Pro, which you'll find in our Aquamaster spare parts page. With the new Pro2 and Pro3 range there's no replacement available from our distributor, so once the electrode wears out you'd have to buy the whole meter again.

• How long does the electrode last?

  The electrode is the part that wears out in any pH meter, and it usually lasts between one and two years of normal use. Once it dies, the device stops working. The advantage of the P160 Pro is that at that point you only need to replace the electrode and you can keep measuring.

• What batteries does it use?

  It runs on three AG-13 button batteries, which are very easy to find and replace. Since it's a pocket meter, power consumption is minimal, so the batteries will last you a long time.

• Is this worth it more than the Pro2 Pocket Meter?

  If you're after the more modern generation, with a better screen and more precision in some ranges, take a look at the Pro2 Pocket Meter. If what you want is a device you can keep alive year after year by replacing the electrode, this P160 Pro is the one for you. Over the medium term, it usually pays off more.

• How long will it take to receive it?

  Our supplier handles this model on a made-to-order basis, so the delivery time can be longer. If you need an approximate date before buying, contact us Monday to Friday from 10:00 to 19:00 and we'll confirm it for you.
