Reviews: Fluke i2000 Flex AC Current Clamp

Rated 4 out of 5 by from Accurate This flex CT does work well and I have had mine for many years when they first came out. The ability to wrap around several different conductors makes this a required product for the field. The problem with this product is that the inner flex is a spring that if it is stretched it is permanently damaged and must be replaced. The second problem with this product is that it cannot be calibrated so you need to check for accuracy on a regular basis to make sure you are good to go. These are the only two items where I have seen the weakness and I do recommend the product however one must take care of the equipment.

Rated 5 out of 5 by from Excellent product with Fluke 233 and wireless screen The i2000 flex probe make it possible to measure amps in a panel with very little space to work. Most clamp on meters needs space for the meter itself and in most cases you cannot reach the cores, especially if more than one core is installed. The i2000 is flexible, needs very little space and very easy to fit around cores.
