Product Description
The AquaPro Digital TDS & EC Meter with Hold Function is a portable pen-style water tester designed for quick water-quality checks. It provides a digital reading that can be locked on the screen, making it easier to remove the meter from the sample and record the result.
The matching official AquaPro TDS Meter Pen listing measures total dissolved solids from 0 to 9999 ppm. TDS is commonly estimated from the electrical conductivity of the water, but the public product page does not confirm a separate direct EC display range for this exact pen.
Before publishing a direct EC specification, confirm the model and display modes of the supplied unit with Inaya Scientific. The meter is suitable for routine checks of drinking water, reverse-osmosis systems, aquariums, hydroponic solutions and other non-regulatory water applications.

Product Overview
Total dissolved solids are the combined dissolved substances represented as a concentration in ppm or mg/L. Portable TDS meters generally use the electrical conductivity of the sample and a conversion factor to estimate the displayed TDS value.
The AquaPro pen is intended for fast comparative monitoring rather than a full chemical analysis. It can help users compare tap water, filtered water, RO output, aquarium water or nutrient solutions and identify meaningful changes over time.

Key Benefits
Fast Digital Reading
The LCD provides a direct numerical result without requiring colour comparison or manual titration. This is useful for frequent routine checks.
Hold Function
The HOLD button locks the displayed value. The meter can then be removed from the sample so the user can read or record the result more conveniently.
Portable Pen Design
The slim body is easy to carry between testing locations. It is suitable for home, field, aquarium, hydroponic and water-filter service use.
Wide TDS Range
The matching AquaPro listing covers TDS readings from 0 to 9999 ppm. This range supports comparative testing across different types of water and nutrient solutions.
Simple Routine Operation
The meter uses straightforward ON/OFF and HOLD controls. Users should still follow the supplied manual for immersion depth, calibration and maintenance.
Who Should Buy This Product?
- Households checking tap, filtered or RO water
- RO and water-purifier technicians
- Aquarium and fish-keeping users
- Hydroponic growers
- Water-treatment service providers
- Schools, colleges and training laboratories
- Field technicians requiring a portable screening meter
- Retail, commercial and institutional procurement teams
Usage and Handling Summary
Follow the instructions supplied with the exact model. The general procedure below is suitable for common pen-style TDS and conductivity testers.
- Remove the protective cap and inspect the sensor area for contamination.
- Rinse the sensor with clean or deionized water before testing.
- Collect the water sample in a clean container when direct immersion in the source is not practical.
- Switch on the meter.
- Immerse only the sensor section and keep the water below the maximum immersion line.
- Move the meter gently in the sample to release trapped air bubbles.
- Wait for the displayed value to stabilise.
- Press HOLD to lock the reading when required.
- Remove the meter and record the value.
- Rinse the sensor after testing and replace the protective cap.
Handling Precautions
- Do not immerse the complete meter body unless the supplied model is confirmed as fully waterproof.
- Keep water below the marked immersion line.
- Do not touch or scratch the sensor electrodes.
- Rinse the sensor between different samples to reduce cross-contamination.
- Avoid testing very hot liquids unless the supplied manual confirms the permitted temperature range.
- Replace weak batteries when the display becomes faint or unstable.
- Use the correct calibration solution and procedure if calibration is supported.
- Keep the meter away from strong impact, direct heat and prolonged moisture exposure.
Limitations and Important Considerations
- A TDS meter does not identify which individual salts, minerals or contaminants are present.
- TDS is generally estimated from electrical conductivity using a conversion factor, so different meters can show different TDS results for the same sample.
- The matching official AquaPro pen page verifies TDS measurement but does not publish a separate direct EC display range.
- Confirm the exact model before advertising the meter as a direct TDS and EC dual-display instrument.
- The meter does not confirm microbiological safety, pathogens, arsenic, lead, pesticide residues or other specific contaminants.
- TDS alone cannot determine whether water is safe to drink.
- Temperature, calibration condition, contaminated electrodes and sample movement can affect the reading.
- Formal regulatory, laboratory or compliance decisions may require an appropriate calibrated instrument and accredited testing.
- Accuracy, resolution, calibration method, warranty and country of origin should be confirmed for the supplied unit.

The HOLD function locks the current value on the LCD. This lets the user remove the meter from the sample and read or record the result without the number changing.
Can the AquaPro meter test drinking water?
Yes, it can be used to check and compare TDS in tap, filtered and RO water. A TDS reading alone does not prove that water is microbiologically or chemically safe to drink.
Can this meter be used for an aquarium?
Yes, it is suitable for routine aquarium and fish-tank water checks. Aquarium care may also require pH, ammonia, nitrite, nitrate, hardness and dissolved-oxygen testing.
Is the AquaPro meter suitable for hydroponics?
Yes, portable TDS and conductivity meters are commonly used to monitor hydroponic nutrient solutions. Growers should follow the EC or TDS target recommended for the specific crop and nutrient system.
What is the TDS measurement range?
The matching official AquaPro TDS Meter Pen listing states a range of 0-9999 ppm. Confirm the range printed on the supplied unit before publishing the final specification.
Does this AquaPro meter show EC directly?
The public AquaPro TDS-1-C listing does not verify a separate direct EC display range. Contact Inaya Scientific to confirm whether the supplied unit has a mode button for direct EC readings.
How should I clean the meter after use?
Rinse the sensor section with clean or deionized water and shake off excess water gently. Do not scratch the electrodes, and replace the protective cap after cleaning.
Does the AquaPro TDS meter require calibration?
Calibration requirements depend on the exact model. Contact Inaya Scientific for the manual, supported calibration solution and procedure before attempting adjustment.
