The ROLA-CHEM ORP Heavy Duty Probes 550136 and 550209 have some differences. They may be made from different materials, which affects their durability and compatibility with chemicals. Each probe can measure ORP levels differently, so one might suit your needs better. They also have different maximum temperatures they can handle. One may respond faster to changes, which is important for certain uses. Lastly, they might require different levels of maintenance. Checking the manufacturer's info can help you decide which is best for you!
