Aqua Master Tools H600 Pro Handheld Meter - pH, EC, TDS, PPM & Temp

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

Checking nutrient solutions with separate testers costs time and invites inconsistent readings. The H600 Pro covers pH, EC, TDS, PPM and temperature in one handheld unit. Automatic temperature compensation adjusts readings across its 0-50°C compensation range, and a calibration indicator tells you when recalibration is due.

This single meter suits hobbyists and regular indoor growers who monitor reservoirs in hydroponic systems, and it works as a portable check tool for commercial teams moving between rooms. It is sold each, with a 9-volt battery and a carrying case included.

Key Features & Benefits

• Five measurements in one meter — check pH, EC, TDS, PPM and temperature without switching devices.
• 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, signalling when to recalibrate.
• Auto power-off and battery indicator — the meter shuts off after 8 minutes and shows battery status.
• Water-resistant build — the housing is rated IP62 and the electrodes IP67.

Who Should Use H600 Pro

Growers who manage nutrient solutions in hydroponic systems and want one portable meter for routine reservoir checks. It suits both newcomers and experienced operators.

About Aqua Master Tools H600 Pro

The Aqua Master Tools H600 Pro is a handheld meter for liquids. It measures pH from 0.0 to 14.0, EC from 0.0 to 19.9 mS/cm, TDS from 0.0 to 19.99 PPT, PPM from 0 to 1999 and temperature from 0°C to 50°C. It uses a 700 PPM scale, measures 8.27 x 4.72 x 2.36 in and ships at 1.229 lb.

Frequently Asked Questions

Q: What does the H600 Pro measure?
A: It measures pH, EC, TDS, PPM and temperature in liquids. You switch between parameters on the same handheld unit.

Q: How accurate is it?
A: pH accuracy is ± 0.1 pH. EC, TDS and PPM are ± 2% of full scale, and temperature is ± 0.5°C.

Q: How do I calibrate it?
A: pH uses 2-point auto calibration at 4.0 and 7.0 pH. EC uses 1-point auto calibration with standards of 1.4, 3.0 or 12.88 EC. A calibration indicator shows after a successful calibration and disappears after 30 days.

Q: What does PPM scale 700 mean?
A: It is the conversion factor the meter uses to turn an EC reading into a PPM value. Check that your nutrient guidance uses the same scale before comparing numbers.

Q: What power does it use and what is included?
A: It runs on one 9-volt battery, which is included. A carrying case is also included.

Q: Is it waterproof?
A: The housing is rated IP62 and the electrodes IP67. Keep the housing out of submersion and rinse the electrodes after use.
