Amtra Digital Conductivity & TDS Tester
The Amtra Digital Conductivity & TDS Tester ATC is a compact and accurate electronic meter for quickly measuring the conductivity (EC in µS) and TDS (ppm) of aquarium water. Its practical pen design makes it easy to take with you and use anywhere.
Accurate measurement with ATC
The tester is equipped with automatic temperature compensation (ATC), which automatically corrects measurements based on water temperature. This ensures reliable and stable results in both freshwater and seawater.
Measuring range
- EC: 0 – 9990 µS
- TDS: 0 – 9990 ppm
- Temperature: 0.1 – 80.0 °C / 32.0 – 176.0 °F
Key Features
- Fast and precise measurement of EC and TDS
- Automatic Temperature Compensation (ATC)
- Automatic switch-off after 5 minutes
- Hold function for easy reading
- Display in °C or °F
- Suitable for beginners and advanced aquarists
Usage
- Remove the protective cap from the electrode.
- Press ON/OFF and place the electrode in the water to be measured.
- Wait until the value is stable and press HOLD.
- Remove the tester from the water and read the value.
- Preferably rinse the electrode with osmosis water after use.
The SHIFT button allows you to switch between EC and TDS displays and between °C and °F.
Calibration
The tester can be easily calibrated automatically using a standard buffer solution, for example, 1413 µS. Regular calibration is recommended for intensive use or when high measurement accuracy is required.
A practical and reliable solution for monitoring water quality in any aquarium.
