The Meascom Hydroponics Test Kit allows growers to quickly measure these important water quality parameters:

• pH – to maintain the slightly acidic conditions required for optimum nutrient availability.
• Electrical Conductivity (EC) – to monitor dissolved nutrient concentration and ensure plants receive the correct nutrient strength.
• TDS means total dissolved solids and is used by many growers as an equivalent to EC.
• Salinity to avoid excessive salt build up
• Temperature affects nutrient uptake and root health

Monitoring these parameters regularly helps maintain consistent growing conditions, improve crop performance and reduce the risk of nutrient deficiencies or lockout.

The Kit Includes

• Professional 5-in-1 pH & EC Meter
• pH 4.01 Calibration Buffer Solution
• pH 6.86 Calibration Buffer Solution
• EC 1413 µS/cm Calibration Solution
• 3M KCl Storage Solution
• Calibration Cups for pH and EC Solutions
• Operating Instructions
• Australian Engineering Support

Ideal For

• Commercial hydroponic growers
• Indoor farming systems
• NFT and DWC hydroponic systems
• Greenhouse vegetable production
• Educational and research facilities
• Serious home growers

Hydroponic growers commonly refer to EC as the nutrient strength or nutrient concentration of the solution. While an EC meter measures electrical conductivity rather than individual nutrient ions, it provides the practical measurement growers use every day to manage nutrient levels and maintain healthy plant growth.

What Does This Meter Measure?

Professional hydroponic growers monitor more than just pH. This verified 5-in-1 meter measures the key water quality parameters that influence nutrient availability and plant growth.

pH

The pH level determines how readily plants can absorb nutrients. Most hydroponic systems perform best between pH 5.5 and 6.5. Regular monitoring helps prevent nutrient lockout and poor plant growth.

EC (Electrical Conductivity)

EC measures the total concentration of dissolved fertiliser salts in your nutrient solution. It is the preferred measurement used by many commercial growers for adjusting nutrient strength.

TDS (Total Dissolved Solids)

TDS is a calculated value based on the EC reading and provides an alternative way of expressing nutrient concentration. Some nutrient charts are published using TDS rather than EC, and this meter displays both.

Many home growers are familiar with TDS meters, while commercial growers often use EC meters. Both measurements indicate nutrient concentration. This professional meter displays both EC and TDS, allowing you to follow whichever nutrient chart or growing guide you prefer.

Salinity

Salinity is primarily useful when testing brackish or saline water, aquaculture systems and certain specialised growing applications. It can also help identify unwanted salt build-up.

Temperature

Water temperature affects oxygen levels, nutrient uptake and root health. Monitoring temperature alongside pH and EC provides a more complete picture of your hydroponic system.

Frequently Asked Questions

How often should I test my hydroponic nutrient solution?

Most commercial growers check pH and EC daily, while smaller systems should be tested at least several times each week.

Why is pH important?

Even when nutrients are present, incorrect pH can prevent plants from absorbing them efficiently.

Why measure EC?

EC provides a quick indication of dissolved nutrient concentration, helping you maintain the correct nutrient strength for healthy plant growth.

Is an EC meter the same as a nutrient tester?

In hydroponics, yes—many growers use the terms interchangeably. An EC meter measures the electrical conductivity of the nutrient solution, which is widely used as an indicator of nutrient strength. While it does not directly measure individual nutrients such as nitrogen or potassium, it is the standard method used to monitor and adjust nutrient concentrations in hydroponic systems

Can I use this kit for all hydroponic crops?

Yes. The kit is suitable for vegetables, herbs, leafy greens, fruiting crops and most commercial or hobby hydroponic systems.
