YexSensor YEX-TDS-100 Pen TDS Meter: Portable Total Dissolved Solids Testing for Water Quality Checks

In drinking water inspection, process water control and laboratory sample screening, TDS is a fast reference indicator for dissolved substances in water. YexSensor YEX-TDS-100 Pen TDS Meter provides a portable way to check total dissolved solids and temperature at the sampling point, helping users confirm water quality condition without waiting for fixed instruments.

Core Technical Advantages: Wide Range, Temperature Compensation and Field-Friendly Operation

Wide Measuring Range

The 0-9999 mg/L measuring range covers common field and laboratory TDS screening needs, from low-concentration water checks to higher dissolved solids reference measurements.

Simultaneous TDS and Temperature Display

The LCD displays TDS value and current sample temperature together. This helps users judge whether a reading is taken under reasonable temperature conditions.

Automatic Temperature Compensation

Automatic temperature compensation from 0 to 50 deg C helps improve data consistency when measurements are taken in different water temperatures.

Simple Lock and Calibration Functions

The HOLD function locks current data for easy reading and recording. One-point automatic correction supports routine calibration after long-term use.

Operation and Maintenance Guide

Measurement Preparation

Pull out the electrode protection cover without twisting it. Press ON/OFF, immerse the electrode sensing area in the sample, stir gently and wait for the reading to stabilize.

Calibration and Electrode Activation

The TDS meter is calibrated before shipment. If the electrode is dry after storage, soak the electrode part in clean water for 5-10 minutes before measurement. Use a proper standard solution when calibration is required.

Storage and Maintenance

Keep the electrode clean and cover it after use. Store the meter in a cool and ventilated place. Replace batteries when the low-voltage symbol or dim display appears.
