HANNA INSTRUMENTS PH METER, 2PH - 16PH, 0.01PH, -0.05PH HI-98128 By

I use this product everyday for my job as a chemical representative, and it is ideal for accuracy and convenience! Great product!

excellent

With my ph 8.00 tap water this ph meter makes adjusting nutrient solutions for gardening in containers possible. Consistently matched a reference ph meter after an easy calibration process. Waterproof, hardy, and consistently accurate.

Does exactly what you need it to do.

Me funcionó bien para para muestras de laboratorio, de aproximadamente 4.5 de pH. Llevo un año con el y se descompuso el electrodo pero, tiene la ventaja que puedes conseguir el electrodo y reemplazarlo sin tener que comprar el equipo completo . Ya se compró e instaló y funciona excelente. Fue una buena compra.

A+

I have been using the Hanna pH/Temperature tester for two months now. It gives relatively accurate readings, and is easy to use, and calibrate (using the calibration solutions...sold separately). I keep mine submerged in a balanced salt solution. It is critical to keep the electrode hydrated at all times. If it should dry out, the life of the electrode will lose its accuracy, and may have to be replaced. I use mine to gauge the acidity of cheeses that I am making from milk products. The reason I only gave it a 4/5 is because you must recalibrate it after4 each usage. You must also purchase the standardizing solutions separately....an expensive proposition in the long run. But, I would purchase this model again.
