TRANS INSTRUMENT Eco pH+ Pen (Test pH)
Eco pH+ (Aquaria, Aquaculture) Pre-Calibration
The ECO pH+ is specially designed for use in aquaria and aquaculture environments. It enables users to perform accurate pH tests on aquarium water with ease, providing digital readings without the need for color comparison or liquid test kits. This eliminates the risk of overdosing when adjusting water pH, which can introduce harmful chemicals into the water. The device allows for multiple daily tests using small, precise dosages, minimizing stress on fish and reducing the chance of water shock or fatalities. Compared to traditional liquid test kits, the ECO pH+ offers greater convenience, accuracy, and safety for daily water maintenance.

I’ve been using the Eco pH+ for two months now and it’s a game-changer for my freshwater tank. I no longer have to worry about overdosing or matching colors. The digital read is fast and accurate. My fish seem more stable, and I can adjust pH daily without stress.
Natalie Payne –
The device works well for regular pH checks. It’s much easier than the old liquid kits. I still need to check the calibration occasionally, but overall it’s reliable and saves time.
