Question

Where can I get calibration solutions for an ORP sensor?

Answer

Vernier does not sell calibrating solutions for the ORP Sensor.

ORP reference solutions can be purchased from Hach Company. The order code for a bottle of 500 mL of 200 mV reference solution is 25M2A1001-115. The order code for a bottle of 500 mL of 600 mV reference solution is 25M2A1002-115.

Cole Parmer also carries ORP standard solution, order code: EW-05730-55.

We strongly recommend that you purchase reference standards rather than prepare your own standards. However, the directions for preparing your own ORP reference standards are available upon request.
