What does the Aqua Master H600 Pro measure?
The H600 Pro measures pH, EC (conductivity), PPM (700 scale), TDS (in PPT), and temperature in liquid solutions. It gives direct EC readings and converts them into PPM or TDS for convenience. For consistent comparisons, EC is the most reliable reference.
What are the measurement ranges and accuracy of the H600 Pro?
The meter reads pH from 0.1–14.0 (±0.1), EC from 0.0–19.9 mS/cm (±2%), PPM from 0–1999 (700 scale), TDS from 0.0–19.99 PPT, and temperature from 0°C–50°C (±0.5°C). It includes automatic temperature compensation for accurate EC readings in varying temps.
How do I calibrate the Aqua Master H600 Pro?
Calibrate pH with pH 7.0 first, then pH 4.0 using automatic 2-point calibration. EC is calibrated with a 1413 µS/cm solution. Always calibrate before first use and repeat monthly or more often if testing daily or using organics.
Can I reuse calibration solution or dip into the bottle?
No—always pour fresh solution into a clean cup to avoid contamination, and discard it after use. This keeps your calibration accurate and extends electrode life.
Are the electrodes on the Aqua Master H600 Pro replaceable?
Yes—the meter includes both pH and EC electrodes, and they are fully replaceable. Replace them if calibration consistently fails, readings drift, or probe response becomes slow despite cleaning.
How do I store and clean the Aqua Master H600 Pro electrodes?
Store the pH electrode wet in KCl storage solution using the protective cap. Never store it dry or in plain water. Rinse after every use, clean with proper electrode cleaner, and recalibrate when needed. EC probes only require rinsing and drying.
Can the Aqua Master H600 Pro be used in hydroponics, aquariums, or pools?
Yes—the H600 Pro is ideal for hydroponic mixing tanks, aquariums, water features, and similar applications. For pools/spas, it provides accurate readings but may not replace all standard test methods.
Why is my pH reading drifting or slow on the H600 Pro?
Likely causes include a dry or dirty pH probe, contaminated calibration solution, or big temperature differences. Try cleaning, rehydrating in KCl, and recalibrating. EC is less sensitive but can also be affected by salt buildup or bubbles.
What’s the correct way to use the H600 Pro for pH and EC testing?
Mix your nutrients first. Measure EC, adjust if needed, then measure and adjust pH. Rinse the probe before and after each test, and let readings stabilise before recording them. Avoid testing in concentrated solutions—use only mixed samples.
How waterproof is the Aqua Master H600 Pro?
The meter body is IP62 (dust and splash-resistant), while the electrodes are IP67 rated for wet environments and brief submersion. It’s suitable for grow-room conditions, but don’t leave it soaking in reservoirs full-time.
What kind of battery does the H600 Pro use?
The meter runs on a single 9V battery (included). It also has a battery indicator. If readings look unstable or the screen dims, replace the battery and recalibrate before assuming there’s a fault.
Does the Aqua Master H600 Pro remind me to calibrate?
Yes—it features a calibration reminder that activates after 30 days, helping ensure accuracy over time. Daily users or those in organic systems may benefit from calibrating more frequently.
Can I use the H600 Pro for field testing or just in the lab?
Absolutely—the rugged build and included carrying case make it perfect for both field use and bench setups. It’s a reliable tool for growers, techs, and hobbyists alike.
What’s the fastest way to get stable readings with the H600 Pro?
Use a clean, well-mixed sample. Rinse the electrode, swirl gently to release bubbles, and let the reading settle before recording. If readings lag, clean the probe and let temperature stabilize.
What’s the best practice routine for the Aqua Master H600 Pro?
Rinse → measure in a mixed sample → rinse again → store the pH probe in KCl solution → clean and calibrate on schedule. Don’t let the pH probe dry out, and never skip calibration before trusting results.
