Why you need good quality digital pH meter
The differences are noticed in the field between two pH meters’ readings, even the two same digital pH meters. This can get many agriculturists bemused with the true value of the pH of the medium on which they are cultivating their plants. This article will help resolve the confusion of the readings.
The acidity or alkalinity of the land or solution, which is very crucial with farming plants, is calculated with a pH scale. The pH is a decisive element in the plant’s growth as it’s directly interrelated to the availability of the nutrients. A few cultivators observed that their pH readings normally fluctuate when tested with 2 different devices in the same nutritive solution. There are various reasons that can be attributed for this variation.
The first reason could be that both the devices are using different batteries in term of brand or voltage. The other reason could be that one device could be using older battery while other is having a new one. We all know that batteries provide the same power, yet it’s a fact that voltage from older battery is generally much weaker then the newer one, and that can be the cause of difference in pH.
Unobserved grunge or dirt on probes can as well impact the pH reading’s accuracy. Thus, you should clean your pH devices on a regular basis to forestall the assemblage of grunge and salt crystals.
It’s very important to find out what kind of pH meter you are using, analog or digital. If you have a choice always go for digital as it’s easier to handle and more promiscuous.
