What is the difference between LS3 & LS3i ?
The LS3i features a few minor refinements, such as:
- solid reverse side (no more inserted plate)
- slightly larger front label (but same OLED)
- less torsion and bending sensitivity
- less temperature sensitivity (almost perfect temp. compensation)
- 10kN higher true breaking strength (15 instead of 14 tons)
- better IP rating (IP68-0.1m instead of IP67)
It must be noted that the electronics (PCB) are 100% identical.
The shape of D-connector has changed slightly. It’s 2mm smaller for LS3i because the ring strength has increased by 1mm, therefore the foam for tough-cases has also changed. NOTE: The LS3i will NOT fit in the “old” cases for the LS3!
The polycarbonate display cover screen and label are slightly larger for LS3i to offer more sealing area, and the LS3i label is glossy, as opposed to satined for the LS3.
