Redox (ORP) Calibration Fluid - 220mV Standard

GHL calibration fluids come in a handy 50 mL bottle, making regular probe calibration fast and easy. All GHL measurement electrodes are made of the highest laboratory grade materials. To ensure consistent performance and accuracy, pH probes should be calibrated regularly; we recommend re-calibration every 30-60 days. 

ORP probes are calibrated against a carefully calibrated standard. Regularly calibrating your Redox/ORP probe with the 220 mV calibration solution will ensure that your probe is delivering accurate and stable readings.
