The Apera Instruments AI1108 pH Calibration Buffer Solution Kit includes two 8oz bottles of pH buffer solutions (pH 4.00 & pH 7.00), and one 4oz bottle of 3M KCL storage solution for pH/ORP electrodes.

Features:

• High Accuracy (±0.01 pH): standardized against NIST certified pH references within 0.01 pH at 25°C (77°F). Ideal for the calibration of all kinds of pH meters
• Color-coded, Double-sealed, 2-Year shelf life
• The 3M KCL Storage Solution helps keep the sensitivity and accuracy of your pH probes
• Non-hazardous product.
• The color-coded buffer solutions are standardized against NIST certified pH references within 0.01 pH at 25°C (77°F).
• It's ideal for the calibration of all kinds of pH meters. Since pH level is affected by temperature, a temperature/pH reference chart is provided on the bottle label for reference.
• The 3M KCL Storage Solution helps keep the sensitivity and accuracy of your pH probes.
• All the solutions are double-sealed, not subject to the DOT shipping restrictions, and have a 2-year shelf life. The expiration date is printed on the bottle.
