Why this part number
Keep OPTIMACALKIT-ZERO on its own BOM line so windows, lamps, PCBs, glands and brackets can be replaced on their own cycle. Do not bury it under 2108N4000N, and do not fit XCD or XNX spares on Optima optics.
Spares and mates
OPTIMACALKIT-ZERO is Searchpoint Optima Plus Calibration. This SKU is a spare or accessory and needs an Optima Plus detector. Matrix: product-2698. Do not substitute Sensepoint XCD cartridges or XNX personalities.
Typical applications
Use OPTIMACALKIT-ZERO against installed Optima Plus points: dust barriers after deluge, flow housings on extractive loops, cups and cylinders at annual gas. Match the detector thread (M20 vs NPT) before the box ships.
