Aim-TTi BS407 Ohmmeter, 2000 Ω Max, 1μΩ Resolution, 4 Wire

Portable instrument (98 x 219 x 240mm, 1.5kg) capable of measuring very low resistance to high accuracy. Unusually wide measuring range combined with features such as a 20mV clamp makes for wide range of applications.

Wide measurement range of 1mΩ to 20kΩ
Four terminal measurement using Kelvin lead set
High basic accuracy of 0.1%
Current reversal switch for thermal EMF detection
Current diversion switch for easy zero setting
Battery operation (Ni-MH) with built-in charger
Minimal warm-up time
Switchable 20mV clamp for 'dry circuit' testing

Kelvin test lead set, operating manual, mains lead.

The Aim-TTi ohmmeter has a wide measurement range between 1μohm and 20kohm. This ohmmeter is fully optimised for accurate measurement of low resistance with a resolution of 1μohm. This ohmmeter generates sufficient test voltage across the unknown resistance to combat noise and reduce thermal EMF effects to manageable levels. This instrument is protected against the back-EMF of its test current from any inductance. It is protected against external voltage sources, delivering up to 1amp. Protection against greater abuse is provided by non-flammable fusible resistors. This exceptionally wide range makes it suitable for a greater variety of applications than other micro-ohmmeters.
