Aqua Master Tools P50 Pro pH Temp Meter - pH 0.0-14.0 - Temp 0-50°C - IP67 Waterproof

Check pH and Temperature in One Pass - Waterproof Pen Meter

Nutrient solution that drifts out of range slows vegetative growth and flowering, and swapping between two tools wastes time. This handheld pen reads pH and temperature together, compensates for temperature automatically, and calibrates with a two-point auto routine. Its IP67 rating means splashes and dunking in the reservoir will not stop it.

As a single unit, it suits home gardeners, small indoor setups and commercial growers who want a spare or a dedicated meter for each room or hydroponic system.

Key Features & Benefits

• pH range 0.0 to 14.0, ±0.1 pH accuracy — covers the full scale for nutrient solutions and water checks.
• Temperature 0°C to 50°C (32°F to 122°F) — reads solution temperature alongside pH, with 0.1°C resolution.
• 2-point auto calibration — calibrates at pH 4.0 and 7.0, with an indicator showing correct calibration.
• IP67 waterproof — withstands wet environments around reservoirs and trays.
• Battery indicator and auto power-off — the meter shuts off after 8 minutes, and three AG-13 button cell batteries are included.

Who Should Use Aqua Master Tools P50 Pro pH Temp Meter

Growers who manage nutrient solutions in hydroponic systems or soil-free media, and anyone who needs quick, repeatable pH and temperature checks, will find this meter practical. It works for hobby and commercial cultivation alike.

Frequently Asked Questions

Q: How accurate is the P50 Pro?
A: pH accuracy is ±0.1 pH, and temperature accuracy is ±0.5°C. Temperature resolution is 0.1°C.

Q: How do I calibrate it?
A: The meter uses 2-point auto calibration with 4.0 and 7.0 pH solutions. An indicator confirms when calibration is correct.

Q: Is it waterproof?
A: Yes, it carries an IP67 rating, so it handles splashes and brief immersion. That makes it suitable for use around reservoirs.

Q: Are batteries included?
A: Yes. It runs on three 1.5 V AG-13 button cell batteries, which are included. A battery indicator shows when power is low.

Q: What does automatic temperature compensation mean?
A: pH readings shift with solution temperature. The meter adjusts for this across 0°C to 50°C so readings stay consistent.
