There is a hole in the bottom of the DRB 200 well. Is this a manufacturing defect?
Summary
Hole in the bottom of the DRB 200
Answer
No, the Hach DRB-200 reactor blocks (P/N LTV082.XX.XXXXX AND DRB-XXX) may have tiny holes in the bottom of the block. This is normal because there is just one ground plate carrying all the different types of its wells. So, due to the bigger diameter of the 16mm block you can see this little hole. This has no influence to the function of the reactor. The plate on the bottom prevents any fluids from entering into the electronics. Troubleshooting guide image
