Aqua Master Tools E50 Pro2 – EC and Liquid Temperature Meter

Aqua Master Tools E50 Pro2 EC/Temp – IP67-rated waterproof EC and temperature meter

The Aqua Master Tools E50 Pro2 is a precision EC and temperature meter designed for quick testing of water and nutrient solutions. It allows you to monitor electrical conductivity (EC) and liquid temperature, making it ideal for hydroponics, gardening, irrigation systems, and other applications requiring regular monitoring of solution parameters.

The E50 Pro2 is an improved version of the E50 meter. It features an easy-to-read black display with white characters, is powered by standard AAA batteries, and includes a calibration indicator. Users can also choose to display EC results with a resolution of 0.01 or 0.1 mS/cm.

Built-in automatic temperature compensation (ATC) accounts for the effect of liquid temperature on conductivity measurements, making it easier to obtain stable and comparable results.

The housing has an IP67 protection rating, and the meter floats on the water’s surface. The replaceable electrode extends the device’s service life without requiring replacement of the entire meter.

What is the Aqua Master Tools E50 Pro2 EC meter used for?

The meter allows you to monitor the electrical conductivity (EC) of a solution, which is one of the basic parameters used in the preparation of nutrient solutions. The measurement enables you to assess the concentration of dissolved mineral salts and facilitates the precise preparation of a nutrient solution.

The E50 Pro2 can be used, among other things, in:

• hydroponics
• indoor cultivation
• gardening
• irrigation systems
• nutrient solution monitoring
• aquariums
• auxiliary laboratory applications
• daily monitoring of liquid parameters

Automatic Temperature Compensation (ATC)

The electrical conductivity of a liquid changes with its temperature. The Aqua Master Tools E50 Pro2 features automatic temperature compensation in the range of 0–50°C, allowing the device to automatically account for temperature effects when performing EC measurements.

Manual EC Calibration

The E50 Pro2 allows for manual EC calibration. The meter can be calibrated using an appropriate EC calibration solution, which facilitates regular checks and ensures accurate readings.

Replaceable Electrode and IP67 Water Resistance

One of the most important advantages of the E50 Pro2 is its replaceable electrode. When the electrode wears out, there is no need to replace the entire unit, which can significantly extend the meter’s service life.

The IP67-rated housing protects the device when operating in humid environments. An additional safety feature is the design that allows the meter to float on the water’s surface.

FAQ – Aqua Master Tools E50 Pro2

What does the Aqua Master Tools E50 Pro2 measure?

The E50 Pro2 measures electrical conductivity (EC) and liquid temperature. It can be used for water, nutrient solutions, and other solutions whose parameters fall within the device’s measurement range.

What is the EC measurement range of the E50 Pro2?

The measurement range is from 0.00 to 19.99 mS/cm, and the user can select a display resolution of 0.01 or 0.1 mS/cm.

What does ATC stand for in an EC meter?

ATC (Automatic Temperature Compensation) refers to automatic temperature compensation. This feature accounts for the effect of the solution’s temperature on its electrical conductivity.

Is the Aqua Master Tools E50 Pro2 waterproof?

Yes. The device has an IP67 rating. Additionally, the meter’s design allows it to float on the water’s surface.

Can the electrode in the E50 Pro2 be replaced?

Yes. The E50 Pro2 has a replaceable electrode, so when it wears out, you can replace just the measuring element instead of the entire meter.

Does the EC meter need to be calibrated?

Regular calibration helps maintain accurate measurements. The E50 Pro2 features manual EC calibration and a calibration reminder indicator.

What kind of batteries does the E50 Pro2 use?

The meter is powered by 2 AAA 1.5 V batteries, which are included in the package.

Is the E50 Pro2 suitable for hydroponics?

Yes. EC measurement is particularly useful in hydroponic cultivation and when preparing nutrient solutions, as it allows you to monitor the conductivity of the nutrient solution.

How does the Aqua Master Tools E50 Pro2 differ from the E50?

The E50 Pro2 is a newer version of the E50 model. New features include a black display with white characters, AAA battery power, a calibration indicator, and the ability to select the resolution of the displayed EC reading.
