Field Supplies: Calibration Solutions
EQUIPCO NIST Traceable Standards
EQUIPCO calibration solutions are accurate, NIST traceable, and comparable to the instrument manufacturer's solutions in every way except for the cost.
EQUIPCO calibration solutions are identical to instrument manufacturer’s standards, accurate, NIST certifiable, and priced economically. We offer our calibration solutions in both convienent 500 ml bottles and 20 L boxes.
Our pH buffers are color coded (pH 4 red, pH 7 yellow, and pH 10 blue), formulated for a long shelf life, and are resitant to bacteria or mold growth. They are accurate to within 0.01 pH at 25°C, exceeding the capabilities of all field pH meters. they are available in individual 500 ml bottles, 20 L boxes, or as a pH meter calibration kit including 2 bottles of each buffer solution.
Our conductivity buffers are available in either 1000 µS for freshwater or 58,700 µS for saltwater. They are accurate to within 1% at 25°C and can be purchased in 500 ml bottles or 20 L boxes.
We also offer standard zobell solution in a 500 ml bottle for calibrating ORP probes. An ecomonical method for creating Turbidity standards is to mix the NTU value desired using our Formazin solution. Formazin comes in 125 ml bottles and is enough to mix a large amount of turbidity solution.
Traceablity certificates can be provided on request. EQUIPCO calibration solutions work with any of the instruments we offer, cost less, and are always available to ship immediately.
