Stopped working after couple of usage
We bought this equipment to check conductivity of water. After using it for couple of times, the instrument stopped working. If you are buying it, be aware that this will not serve you for a long time. Note: REMOVE BATTERIES AFTER USAGE. BATTERIES THAT COME WITH THIS INSTRUMENT LEAKED THE SAME DAY, EVEN WHEN THE INSTRUMENT WAS SWITCHED OFF.

Possibly USED product.
Everything else came seal packed but why is there crystallisation around the plastic cover/cap? Why are there water droplets and water near the sensor and inside the plastic cover/cap? It seems like this product has been used or tested prior to shipping. There are fingerprints all over the instrument.

¡El Medidor de pH PH20 de Apera Instruments es la herramienta secreta que todo cervecero casero debería tener en su arsenal! 🍺✨ Si alguna vez pensaste que tu cerveza no era buena, pero no sabías por qué, probablemente te faltaba el control perfecto del pH. Con este medidor, tu cerveza no solo será deliciosa, ¡será una obra maestra científica! 🧪 Primero, la precisión de ± 0,1 pH es algo que no se encuentra todos los días, ¡es como tener a un químico personal en tu cocina! Y no hablo de cualquier químico, sino uno que está obsesionado con la perfección y el equilibrio de tu brebaje. Desde el primer uso, me sentí como un mago del pH, asegurándome de que mis mostos fueran perfectos para que la fermentación fuera un éxito rotundo. 🎩✨ Lo mejor es su rango de medición pH 0-14, lo que significa que, si decides medir otras cosas además de tu cerveza, puedes hacerlo sin problemas. No solo sirve para tu cerveza, ¡también podrías usarlo para medir el pH del agua, de tu piscina o incluso de la planta de tu abuela (aunque no lo recomiendo, ¡tu abuela podría no estar tan contenta)! 🌊🌱 El medidor es resistente al agua, lo que es un plus enorme cuando estás rodeado de líquidos en tu laboratorio cervecero (es decir, la cocina). No tienes que preocuparte por derrames accidentales, y si el medidor se moja, ¡se puede secar y sigue funcionando como si nada! 🙌 Y, por supuesto, incluye soluciones de calibración, lo que hace que el proceso sea aún más sencillo. No hay necesidad de complicarse con líquidos raros o procedimientos confusos. ¡Solo calibras y listo, a medir tu pH con total confianza! En resumen, si eres un cervecero que quiere elevar el nivel de sus creaciones, el Medidor de pH PH20 de Apera Instruments es tu nuevo mejor amigo. Con él, tu cerveza no solo será sabrosa, sino científicamente impecable. ¡Salud! 🍻
