pH Tester 6011 - Gondo

Gondo 6011 Electronic Pool pH Tester – Precise Measurement and Calibration Kit Included

Are you checking your pool or spa's pH with colored strips and struggling to distinguish the nuances between 7.2 and 7.6? The Gondo 6011 electronic pH tester puts an end to this guesswork. It displays the exact pH value on its LCD screen in a few seconds, with an accuracy of ± 0.1 pH — enough to properly adjust your treatment and avoid costly dosing errors in terms of products and swimming comfort.

Compact, waterproof, and supplied with its calibration solutions, it is the reference measuring tool for any pool owner who wants to move from approximate control to reliable and reproducible readings, without investing in expensive professional equipment.

Why pH is the Most Important Parameter for Your Pool

Pool water pH must be maintained between 7.2 and 7.6 to ensure three essential things: swimmer comfort, disinfectant efficacy, and equipment protection. Outside this range, the consequences are immediate.

A too low pH (acidic water) causes eye and skin irritation, corrodes the liner, seals, and metal parts, and prematurely degrades electrolyzer cells. A too high pH (basic water) drastically reduces chlorine efficiency — at pH 8, chlorine is only 20% active at its disinfecting capacity — and promotes the appearance of limescale deposits and cloudy water. Precisely measuring pH is not an option; it is the basis of all serious pool maintenance.

A Readable LCD Screen, Immediate Usability

The 21 × 18 mm LCD screen of the Gondo 6011 displays measurements clearly, even in direct sunlight. The measurement range covers the entire pH scale from 0 to 14, with a resolution of 0.1 pH — meaning you directly read 7.3 or 7.5, without interpreting a color on a comparison card.

Its pencil format of 33.5 × 170 mm and its weight of 85 g (batteries included) make it a tool that slips into a pocket or into the storage box supplied with the device. No complex touch screen, no menu to navigate: dip, read, act.

IP57 Waterproof: Designed for the Pool Environment

The IP57 certification guarantees that the tester resists temporary immersion up to 1 meter deep for 30 minutes. This is essential protection for a tool used near water, regularly splashed or handled with wet hands. Unlike entry-level non-waterproof testers that break down at the first drop in the pool, the Gondo 6011 is sized for daily outdoor use throughout the season.

Simple Calibration with Provided Solutions

A pH tester is only accurate if it is regularly calibrated. The Gondo 6011 is supplied with two calibration solutions (pH 4 and pH 7) and a calibration screw, allowing the device to be calibrated immediately upon receipt and to maintain its accuracy over time. Calibration takes less than two minutes: dip the probe into the pH 7 solution, adjust with the screw until 7.0 is displayed, and the device is ready.

It is recommended to calibrate the tester every 4 to 6 weeks during periods of active use, or systematically after prolonged storage. Compatible pH 4 and pH 7 calibration solutions are available separately for refills.

Ideal for Pools and Spas

The Gondo 6011 is perfectly suited for pH control in private pools, spas, and jacuzzis. Its 0–14 measurement range covers all scenarios encountered in these environments. It also makes an excellent verification tool for owners equipped with an automatic pH regulator: even with a Phileo or a Limpido CCEI, regular manual double-checking with an electronic tester remains good practice to detect a potential probe drift problem.
