Description

This handheld conductivity tester operates on the principle of measuring the electrical conductivity of a water sample to estimate its Total Dissolved Solids (TDS) content. It uses a fixed conversion factor to calculate TDS from the measured EC value, providing a practical estimation for non-laboratory applications. The integrated temperature sensor enables Automatic Temperature Compensation (ATC), adjusting readings to a standard reference temperature (typically 25°C) for improved accuracy across its 0°C to 80°C operating range.

Designed for portability and ease of use, the meter features a simple one-button interface to toggle between TDS and EC display modes. Its sealed, pen-style housing is intended for direct immersion in liquids. While suitable for comparative quality checks in field applications, its accuracy is intended for estimation purposes rather than precise scientific analysis.

Key Features

  • Dual-function sensor for simultaneous TDS and EC measurement with a resolution of 1 ppm/1 µS
  • Automatic Temperature Compensation (ATC) corrects for water temperature variations from 0°C to 80°C
  • High-contrast LCD display clearly shows measurement values and active mode
  • Energy-efficient design with auto shut-off after a period of inactivity to extend battery life
  • Robust, waterproof pen-style probe construction suitable for direct immersion testing
  • Factory pre-calibrated with a standard NaCl solution for immediate out-of-box use
  • Simple one-button operation for power-on, mode switching, and holding readings

Applications

  • Monitoring dissolved solids in reverse osmosis (RO) filtered drinking water systems
  • Testing nutrient solution conductivity in hydroponic and aquaponic growing setups
  • Checking water quality parameters in freshwater and saltwater aquarium maintenance
  • Basic water quality assessment for pools, spas, and general water treatment processes
  • Educational demonstrations of water conductivity and impurity concentration

Frequently Asked Questions

Is the battery included with this TDS/EC meter?

No, the meter requires a single 3V CR2032 coin cell battery for operation, which is not included in the package. You will need to provide your own battery. The device features an auto power-off function to help conserve battery life during periods of inactivity.

How accurate is this meter, and does it require calibration?

The meter has a stated accuracy of ±2% for its TDS and EC measurements across the 0-9999 ppm/µS/cm range. It is factory calibrated using a standard NaCl solution and is ready for immediate use. For optimal accuracy over time, periodic recalibration with an appropriate standard solution is recommended, especially if used frequently or for critical measurements.

What is Automatic Temperature Compensation (ATC) and why is it important?

Automatic Temperature Compensation (ATC) is a feature that adjusts the conductivity reading based on the measured water temperature, providing a value corrected to a standard reference temperature (typically 25°C). Since water conductivity changes with temperature, ATC ensures more consistent and comparable readings across different testing conditions, which is crucial for accurate TDS estimation.

Can this meter be used for testing seawater or other high-conductivity liquids?

This meter's maximum measurement range is 9999 µS/cm, which is suitable for freshwater, drinking water, hydroponic solutions, and aquariums. Seawater and many industrial brines have conductivity levels significantly higher than this range (often >50,000 µS/cm), which would exceed the meter's capability and could potentially damage the sensor or provide inaccurate readings.
