Replacement & Compatibility FAQ
Q: Can I use CPM253-MR0105 with third-party pH sensors?
A: The CPM253 is optimized for Memosens digital sensors. Analog sensors require an adapter; contact us for compatibility assessment.
Q: Is CPM253-MR0105 a direct replacement for CM253?
A: Yes — CPM253 is the current product designation for the CM253 series. They are functionally identical.
Q: What is the difference between MR0105 and PR0105?
A: MR = field-mount (remote) enclosure; PR = panel-mount enclosure. Electronics and functionality are identical.
Q: Can this unit be configured via HART?
A: Yes, full HART 7 communication is supported for remote configuration and diagnostics.
Q: Do you provide installation and commissioning support?
A: We provide technical documentation and remote guidance. On-site support can be arranged upon request.
