3 in 1 Digital TDS EC Temp Conductivity Meter

3-in-1 Digital TDS EC Temperature Meter

The 3-in-1 Digital TDS EC Temperature Meter is a portable water testing device designed to measure Total Dissolved Solids (TDS), electrical conductivity (EC), and water temperature. It can be used to check water quality, monitor water filter performance, and measure dissolved solids in water. The compact design and included carrying case make it convenient for home and everyday water testing.

Key Features

• 3-in-1 measurement of TDS, EC, and temperature

• TDS measurement range of 0–9990 ppm (mg/L)

• Built-in digital thermometer

• Automatic Temperature Compensation (ATC) from 1–50°C

• Hold function for convenient reading

• Auto-off function after 10 minutes

• Factory calibrated with a 342 ppm NaCl solution

• Can be recalibrated using a mini screwdriver

• Includes carrying case with belt clip

• Compact and lightweight design

• Includes 2 × 1.5V button cell batteries

Benefits

• Helps monitor the dissolved solids level in water

• Useful for checking water filter performance

• Provides convenient EC and temperature measurements

• Portable design makes it easy to carry and use

• Hold function makes readings easier to record

• Automatic temperature compensation supports more consistent measurements

How to Use

1. Remove the protective cap and switch on the meter.

2. Place the testing probe into the water sample.

3. Wait for the reading to stabilize.

4. Use the mode or display information to check the required measurement.

5. Use the Hold function if you want to retain the reading.

6. Remove the meter, rinse the probe with clean water, and dry it before storage.

7. Store the meter safely in its carrying case.

Cautions

• Rinse the probe after each use to help maintain measurement performance.

• Do not immerse the meter beyond the recommended level.

• Keep the electronic components dry.

• Store in the provided case when not in use.

• TDS and EC readings indicate dissolved substances and conductivity; they do not by themselves confirm that water is safe for drinking.
