Megger TDR900 TDR Cable Fault Locator, 3.7km

The Megger TDR 900 handheld time domain reflectometer/cable length meter has a measurement range that spans from 15ft (5m) to 10,000ft (3km) with a minimum resolution of 20in (50cm). This is an advanced instrument, capable of measuring cable lengths and finding the distance to an open or a short using time-domain reflectometry. It offers exceptional features and a range capability, normally associated with far more expensive instruments. This can be used for any cable consisting of at least two insulated metallic elements, one of which may be the sheath or shield of the cable. The meter has automatic internal matching networks to allow testing of 25, 50, 75, 100, 125, or 150 cables. (These correspond to power, telephony, CATV, and LAN cables).

Accurate to 20in (50cm) throughout the entire range
Extra-large backlit (ICON type 7 segment) LCD
Automatic output impedance control, auto-range, auto-zero, and auto-sensitivity allows for closely matching to a wide range of cables under test.
Only V. O. P (velocity of propagation) settings required
Displays cable length if the cable’s V. O. P (velocity of propagation) is known or displays V. O. P (velocity of propagation) if a cable’s length is known
Automatic output impedance control of 25ohm, 50ohm, 75ohm, 100ohm, 125ohm or 150ohm
20 internal memory locations store up to 20 custom cable
Internal library of 39 standard cables allow for quick and easy measurements for industry standard cable types
