I enjoy making home made hot sauces but giving them a long, stable, unrefrigerated shelf life eluded me for some time, until I started testing each batch for its pH level and adding citric acid as needed. Too little and the dangerous bugs come back; too much and you've got yourself sour sauce, not hot.Cheap pH meters are easy to come by but they usually only include a few sachets of calibration powder, and even then you need to purchase extra distilled water and mix up batches yourself. Again, cheaper, but very inconvenient, and makes you less likely to do it regularly in the first place.No, at £26.99 these aren't cheap, but in terms of saved money from spoilage and in sheer convenience they are a huge boon to me. I can now regularly test the calibration of my two pH meters and give friends my sauces without worrying that in a few days my gift will go off.Very happy.

Für EUR 26,99 (Stand 27.04.2025) erhält man 3 x 250 ml Kalibrierlösungen, welche - ungeöffnet - 3 Jahre haltbar sind. Funktionieren tut das Ganze wie es auch die bisher gekauften Kalibrierlösungen taten, da ist jetzt wenig mit Superlativen um sich zu werfen. Erfüllt den Zweck zum fairen Preis, Punkt.Die Verschlüsse der Flaschen sind auch ok und dicht, insofern gebe ich hier in der Gesamtheit betrachtet 5 Sterne.

This is a review of the Gidigi brand pH Meter Calibration Buffer Solution Kit. Which was priced at £26.99 at the time of posting this review.I use a pH meter to test the water in my aquarium and garden pond. Keeping the meter calibrated is important to ensure the health of my fish.I like these Gidigi solution as I trust the brand. I like that the bottles have a scale on the label to show the effect of temperature on any pH reading which can show higher or lower depending on the temperature of the buffer solution.These are nice large 250ml bottles which will last a long time.

Este kit de soluciones de calibración es específicamente ideal para phmetros de punta de lanza para alimentación, pues el que yo he elegido solo trae soluciones de calibración de pH 4.00 y ph 7.00.Son botellas de 250 ml, por lo que son perfectas para hacer calibraciones con la debida asiduidad. El kit incluye también una botella de 30 ml de solución de mantenimiento de sondas, para poder mantener siempre hidratadas las esponjas de las tapas de los phmetros. Trae a mayores dos vasitos medidores de plástico de 50 ml con pico vertedor.En conclusión este kit es un imprescindible para mantener bien calibrada y cuidada tu sonda, de muy buena calidad y de una marca fiable. Muy recomendable 👌
