Reference electrode refill solutions, as well as several types of gels are available.

pH Buffers

NEW Sensorex pH BUFFER POWDER SACHET PILLOWS are now available to prepare on-site 100mL samples. Sachets are available for pH 4, pH 7 pH 10 buffers and as 90mV and 250mV ORP standards,

Sensorex buffers are accurate to within ± 0.01 pH units @ 25°C and remain stable over long periods of time. Standard packaging is shown below. Buffers are available in pint (473 ml) or gallon (3.784 Liter) sizes.

As with all buffers, these solutions are temperature sensitive. For accurate calibration, heat or cool your buffer solution to 25 degrees C before using. If this is not convenient, compensate for For the thermal errors associated with these buffers.
