R-Tek Professional TDS & EC Meters

A. Product Overview

R-Tek TDS-1396 TDS Meter

The R-Tek TDS-1396 is a handheld digital instrument designed for measuring total dissolved solids in water and liquid solutions. It features a 4 digit LCD display, a temperature range of 0°C to 50°C, and compact dimensions of approximately 188 × 35 × 35 mm.

It is intended for applications where users need convenient monitoring of dissolved solids concentration along with temperature indication.

R-Tek EC-1387 EC Meter

The R-Tek EC-1387 is a digital electrical conductivity meter designed for conductivity measurement in water and liquid solutions. It provides an EC measuring range of 0 to 19990 µS/cm, making it suitable for monitoring solutions across a relatively wide conductivity range.

The listed temperature specifications include:

Temperature Accuracy: ±1°C
Temperature Resolution: 0.1°C

Together, these meters provide dedicated solutions for users who need professional TDS and EC water quality measurements.

B. Working Principle

How a TDS Meter Works

A TDS meter is used to estimate the concentration of total dissolved solids present in water or another compatible liquid sample.

In general, portable digital TDS meters determine dissolved solids by sensing the electrical characteristics of the solution and converting the measurement into a TDS value. The R-Tek TDS-1396 displays the measured result digitally and also supports temperature measurement from 0°C to 50°C. The exact internal conversion method is not specified on the IndustryBuying listing.

How an EC Meter Works

An EC meter measures the electrical conductivity of a liquid. Dissolved ionic substances allow electrical current to pass through a solution, so conductivity can be used as an important parameter when evaluating water and solution characteristics.

The R-Tek EC-1387 measures conductivity from 0 to 19990 µS/cm and provides the measured value through a digital testing instrument.

C. Why It Is Used

R-Tek Professional TDS and EC Meters are used when users need to monitor dissolved solids or electrical conductivity in water and liquid solutions.

The TDS-1396 is useful for checking total dissolved solids and monitoring changes in water quality. The EC-1387 is useful when electrical conductivity needs to be measured directly.

Typical applications mentioned for these product types include:

• Water quality testing
• Laboratory testing
• Hydroponics
• Aquariums
• Aquaculture
• Routine conductivity measurement
• Dissolved solids monitoring
• Liquid solution testing

IndustryBuying specifically lists laboratory, water testing, aquariums and hydroponics among applications for the TDS-1396, and laboratories, water analysis, hydroponics and aquaculture for the EC-1387.
