R-Tek Digital pH Meters

A. Product Overview

R-Tek Digital pH Meters are compact handheld instruments designed for quick and convenient pH measurement in liquids.

The range includes:

R-Tek PH-98081
A digital pH meter with a measurement range of 0.00 to 14.00 pH, 0.01 pH resolution, manual calibration and automatic temperature compensation from 0°C to 50°C.

R-Tek PH-035
A portable digital pH meter variant intended for routine pH testing and water quality applications.

R-Tek PH-010
A professional digital pH meter with a measurement range of 0.00 to 14.00 pH, 0.01 pH resolution, specified accuracy of ±0.1 pH and automatic temperature compensation.

These models provide users with portable options for checking pH levels in different water and liquid testing applications.

B. Working Principle

A digital pH meter determines whether a liquid is acidic, neutral or alkaline.

The sensing electrode is immersed into the liquid sample. The electrode responds to the hydrogen ion activity present in the solution and generates an electrical signal.

The meter processes this signal and converts it into a digital pH reading.

The pH scale normally ranges from:

Below pH 7: Acidic
pH 7: Neutral
Above pH 7: Alkaline

Models equipped with automatic temperature compensation adjust the measurement response according to the temperature of the liquid, helping improve consistency across different testing conditions.

C. Why It Is Used

R-Tek Digital pH Meters are used to quickly determine the acidity or alkalinity of water and liquid solutions.

They are useful for:

• Checking water pH
• Monitoring drinking water quality
• Testing aquarium water
