Note: Comes complete with 0.75 to 1 m (2½ to 3 ft) cable and Electrode Care Instruction Sheet.
Cables may be supplied slightly longer with a maximum length of 1 m (3 ft)

For non-standard cable lengths, add a suffix with the desired length in feet; add $2 per foot to price. (Additional cost of $2 per foot applies to the entire cable length)

Combination electrodes available with detachable cable connector.

BNC connector is standard, for a US connector, add suffix "-U" to model number; consult To Order guide above for pricing.
