How to order

When ordering, suffix the lead-wire cable code to the model number with a space in between.

E.g.
KH-5-350-G4-11 with a glass-coated Ni-plated 3-wire copper cable 5 m long pre-attached
→ KH-5-350-G4-11 D5M3

If no lead-wire cable code is suffixed, the gage is delivered with an advance cable only (25 mm long).
