02 / Coverage
The whole line, on a single axis.
Each bar is one module's ranging envelope, drawn to a shared logarithmic scale from 1 m to 3,000 m. Teal marks the minimum working distance, crimson the published maximum.

05 / Evidence
How this catalogue is allowed to talk about numbers.
Four rules the site holds itself to. They are commitments about presentation, not claims about performance.
01
Every figure carries its condition
A maximum range means nothing without the target reflectivity and visibility it was measured at. Both are printed next to the number, on every model.
02
Unknown stays unknown
Where a parameter is not published for a model, the field is left empty. It is never filled with a family average or a plausible estimate.
03
One published price, no invented ladders
Each model shows its published entry-band unit price. Only LRF3000A1 has a published volume ladder; the rest say so, rather than inventing bands.
04
The datasheet is the authority
The specification table on this site is generated from the same source as the PDF. If the two ever disagree, the datasheet wins and the site is wrong.
06 / Manufacture
Machined, assembled and calibrated in-house.
ERDI reinvests more than 15% of annual revenue into R&D. Production stays vertically integrated in-house — CNC machining, clean-room assembly and automated, per-unit calibration — so every module leaving the factory is tested against its published specification before it ships.
Every ERDI module carries a 2-year warranty. Within the first 12 months, any verified manufacturing defect is replaced with a brand-new unit free of charge. A 30-day trial/return window applies from delivery. Technical support is available for the lifetime of the product.
