Aqua Master Tools H600 Pro Handheld Substrate Meter - pH, EC, TDS, PPM & Temp - 9V Battery Included

Five Readings in One Handheld Meter - 8.27 x 4.72 x 2.36 in

Checking a root zone or nutrient solution with separate tools takes time and invites mistakes. The H600 Pro covers pH, EC, TDS, PPM and temperature in one handheld unit, and it compensates for temperature automatically. A calibration indicator shows when the meter has been calibrated recently, so you know whether to trust a reading.

As a single unit, it suits home gardeners who want one dependable tool for hydroponic systems and soft, moist substrates. It also works as a spare or scouting meter for commercial growers with several rooms to check.

Key Features & Benefits

• Five measurements — read pH, EC, TDS, PPM and temperature without switching instruments.
• Automatic temperature compensation — readings adjust across 0°C to 50°C (32°F to 122°F).
• Calibration indicator — it appears after a successful calibration and disappears after 30 days, which prompts you to recalibrate.
• Battery indicator and auto power-off — the meter shuts off after 8 minutes to conserve its 9V battery, which is included.
• Carrying case included — it protects the meter and makes it easy to move between rooms.

Who Should Use Aqua Master Tools H600 Pro

Growers who monitor nutrient strength and acidity in hydroponic systems or soft, moist substrate will find it useful. It suits both newcomers and experienced operators who want one handheld unit for routine checks.

Frequently Asked Questions

Q: What does the H600 Pro measure?
A: It measures pH, EC, TDS, PPM and temperature. It works in soft, moist substrate or in liquid.

Q: How do I calibrate it?
A: pH uses 2-point automatic calibration at 4.0 and 7.0 pH. EC uses 1-point automatic calibration with standards of 1.4, 3.0 or 12.88 EC.

Q: How will I know when to recalibrate?
A: A calibration indicator appears after a successful calibration and disappears after 30 days. When it is gone, recalibrate before relying on readings.

Q: What does F.S. mean in the accuracy figures?
A: F.S. means full scale. An accuracy of ±2% F.S. is a percentage of the meter's full measuring range, not of each individual reading.

Q: Is it waterproof?
A: The housing is rated IP62 and the electrodes are rated IP67. Treat the housing as splash-resistant and do not submerge it.

Q: What power does it use?
A: It runs on one 9V battery, which is included. It switches off automatically after 8 minutes.
