Aqua Master Tools E50 Pro EC Temp Meter - 0.0-19.9 mS/cm - IP67 Waterproof

Check Solution Strength and Temperature in One Reading - 0.0-19.9 mS/cm

Guessing nutrient strength leads to uneven feeding, and temperature swings skew conductivity readings. The E50 Pro measures EC and temperature together and applies automatic temperature compensation. Its IP67 rating means splashes and brief submersion will not stop it working.

Sold as a single meter, the E50 Pro suits home growers setting up a first hydroponic system and small to mid-size indoor operations that need a handheld for routine reservoir checks. Commercial teams can add one per station or room.

Key Features & Benefits

• Dual EC and temperature readout — one tool covers both checks, with EC resolution of 0.1 mS/cm and temperature resolution of 0.1°C.
• 1-point auto calibration — calibrate against a 1.4 EC reference, with an indicator that confirms correct calibration.
• IP67 waterproof body — withstands wet grow-room conditions.
• Battery indicator and auto power-off — you see when power runs low, and the meter shuts off after 8 minutes.
• Batteries included — it runs on 3 AG-13 button cells supplied with the meter.

Who Should Use E50 Pro EC Temp Meter

Growers who mix nutrient solutions for hydroponic systems, from hobbyists to commercial rooms, and anyone who needs a quick handheld conductivity and temperature check.

About Aqua Master Tools E50 Pro EC Temp Meter

The Aqua Master Tools E50 Pro is a handheld pen meter. It reads EC from 0.0 to 19.9 mS/cm with ±2% F.S. accuracy and temperature from 0°C to 50°C (32°F to 122°F) with ±0.5°C accuracy. It measures about 10.2 x 2.8 x 1.2 in and ships at 0.291 lb.

Frequently Asked Questions

Q: What does the E50 Pro measure?
A: It measures electrical conductivity (EC) and temperature. EC shows how much dissolved nutrient is in a solution. Both readings come from the same probe.

Q: What does automatic temperature compensation mean?
A: Conductivity changes with solution temperature. The meter adjusts the reading across 0°C to 50°C so results stay comparable. You do not have to correct them by hand.

Q: How do I calibrate it?
A: It uses 1-point auto calibration with a 1.4 EC reference. An indicator shows when calibration is correct.

Q: Does it include batteries?
A: Yes. Three 1.5 V AG-13 button cells are included. A battery indicator shows when they run low.

Q: Can I use it in a wet grow room?
A: Yes. It carries an IP67 waterproof rating, so it handles splashes and brief immersion.
