5 Things You need to consider when choosing the ph pen in 2021

There are some things you should consider when buying a ph pen. We spent 22 hours researching the most important things you should consider when buying a ph pen. So should we start with the list of things you should consider?

1. Budget and price matching

Make a list of the things you want in your ph pen and the price you are willing to pay for it. So try to look for a product in that price range and choose the one that appeals to you the most. One tip we would like to give you is: don’t settle for a cheaper product if it doesn’t even have a function you need.

Most ph pens fall within the price range of $ 49.75 to $ 131.99. Therefore, if budget is not a problem and you want the best product for your needs, we advise you to choose the APERA INSTRUMENTS AI209 Value Series PH20 Waterproof pH Tester Kit, ±0.1 pH Accuracy.

If you want something medium range, choose VIVOSUN PH Meter Digital PH Tester Pen for Water. If you have a very low budget, you can choose the one that is the Bluelab METCOM Combo Meter for pH, Temperature, Conductivity (Nutrient) in Water with Easy Calibration, Digital TDS Tester for Hydroponic System and Indoor Plant Grow, Pack of 1

2. Does it have all the features you need?

Most importantly, the ph pen you are purchasing should have all the features you are looking for. In case you don’t even have one, don’t buy! We are saying this because you will not be able to use it for that purpose. If you are a person without budget problems, I would suggest you to choose the best model which is Bluelab METCOM Combo Meter for pH, Temperature, Conductivity (Nutrient) in Water with Easy Calibration, Digital TDS Tester for Hydroponic System and Indoor Plant Grow, Pack of 1

3. The brand

Buying the ph pen from a reputable brand can actually make sense. Not only will it be better than others in terms of “build quality”, but it will also have some extra features, better customer support. Famous brands have multiple service centers across the country, so if you have any problems you can simply take your ph pen to one of their service centers.

4. Warranty Matters!

When you buy a ph pen from a well-known brand, you will get a guarantee. Low-cost products also come with warranties, but the claim process could be tougher. That’s why I always suggest you buy the product from a reputed brand and the one that comes under warranty. It will save you from repair costs in the future. On average, around 21% of people end up paying 40% of the product price for the service! You can save on service costs if the product is under warranty!
