Portable water testers (Handheld)

4-in-1 Meter (TDS, pH, EC, and Temperature)

4-in-1 water quality meter is a multifunctional digital device designed to quickly and accurately measure:

• TDS (Total Dissolved Solids) – indicates the concentration of dissolved substances in water (measured in ppm or mg/L)
• pH – measures how acidic or alkaline the water is (scale from 0 to 14)
• EC (Electrical Conductivity) – shows the water’s ability to conduct electricity (measured in µS/cm or mS/cm)
• Temperature – affects all other readings and is measured in °C or °F

Features

1. Multifunctional 4-in-1 Design

• Eliminates the need for separate instruments.
• Ideal for fast and efficient testing in field and lab environments.

2. Digital LCD Display

• Large backlit screen for easy reading in any light.
• Displays multiple parameters simultaneously (model dependent).

3. High-Precision Probes

• Reliable and accurate sensor tips for each function.
• Detachable or built-in probes depending on model.

4. Automatic Temperature Compensation (ATC)

• Adjusts readings based on sample temperature.
• Ensures consistent accuracy across various conditions.

5. One-Touch Calibration

• Easy calibration with standard buffer and TDS/EC solutions.
• Often supports auto or manual 3-point pH calibration.

6. Portable and Durable

• Lightweight, handheld design with protective case.
• Often waterproof or water-resistant for outdoor use.

7. Power Supply

• Usually powered by AAA batteries or built-in rechargeable battery.

Applications

• Drinking water testing
• Aquaculture and hydroponics
• Swimming pools and spas
• Laboratory experiments
• Industrial wastewater monitoring
• Agriculture and irrigation water testing
