Why You’ll Love It

Featuring a large LCD, auto-calibration with included pH buffers, and ATC (Automatic Temperature Compensation), this hygger meter ensures reliable and precise water measurements, providing accurate readings of TDS, EC, pH, salinity, and temperature. It is compact, portable, and ideal for maintaining a healthy aquatic environment with minimal effort.

Key Features

Complete 5-in-1 Testing

Instantly measures TDS, EC, pH, salinity, and temperature to monitor water quality with precision. The one-button lock reading function helps lock reading even if the TDS Meter is taken out of the sample. Turn on the switch, put the probe into the water, stir (make the small glass ball fully contact the liquid), and the value can be read.

Reliable & Quick Readings

Built to provide consistent results with ATC, a waterproof sensor, and battery-powered convenience. The water meter is equipped with 4 high-sensitivity probes, which can measure PH, TDS, EC, SALT, and TEMP. with high precision at the same time. Shows real-time readings for all parameters simultaneously, with easy-to-read values.

Memory Function

Retains settings between measurements for convenience.

Measurement Ranges & Accuracy

TDS: 0–9999 ppm, 1 ppm resolution, ±2% accuracy;
EC: 0–9999 μS/cm, 1 μS/cm resolution, ±2% accuracy;
pH: 0–00, 0.01 resolution, ±0.05 pH accuracy;
Salinity: 0–9999 ppm;
Temperature: 0.1–60°C / 32–140°F, ATC included.

Widely Application

This hygger 239 pH/TDS meter can help you find out the quality of water. It can be used to test drinking water, swimming pools, aquariums, pH balance, RO system, SPA, or hydroponics.
Basically, all the environments that need to test the pH value can use this WATER tester to get an accurate value. Lightweight design (95±8g) makes it convenient for home or professional use.

Easy Automatic Calibration

Comes with three pH buffer powders (4.00, 6.86, 9.18) for effortless calibration.
Equipped with Automatic Temperature Compensation (ATC) that ensures accurate measurements across a wide range of temperatures (0.1-60°C/32.1-140°F). You can calibrate effortlessly to ensure the accuracy of the measurements. TDS EC is calibrated before leaving the factory and can be used out of the box.

Usage Tips

1. Calibration: Use the included pH buffers for auto-calibration. Immerse the electrode in the solution, press and hold the “CAL” button, and wait for the LED to flash 3 times to confirm calibration.
2. Measurement: Immerse the probe in water (without exceeding the max level), wait for readings to stabilize, and press “HOLD” to lock and read the value only when the reading has stabilized.
3. Before use: Soak the probe in water for two to five minutes to activate the probe before use or calibration.
4. After Use: Rinse the probe with distilled water, dry, and replace the cap.
5. Battery Replacement: Replace the 4×5V LR44 batteries when the display dims or readings become inconsistent.
6. Safe Placement: Keep the meter’s control buttons and battery compartment away from water; only the probe is water-resistant.

Regular Checks: Test water frequently to ensure stable aquarium conditions and optimal plant or fish health.
