Chroma thermal/multi-function data loggers measure temperatures, voltages, and currents
with high accuracy and resolutions. For example, they support 8 types of thermal couples measurement with ITS-90 defined temperature range at 0.5˚C accuracy and 0.01˚C resolution*, while most data loggers in the market are at 1˚C accuracy and 0.1˚C resolution*. Chroma loggers are with 1000VDC channel to channel isolation, which means they can attach thermal couples to objects with high electricity, such as batteries,
solar cells, working PCB, etc., and still get correct data. Many competitors are just

The 17020E test system is specifically designed to meet the diversified requirements for testing secondary battery packs with high safety and stability.

Chroma 11210 battery cell insulation tester is an instrument used for accurately measuring leakage current (LC) and insulation resistance (IR) of battery jelly-roll/dry-cell as well as various insulation materials. In addition to standard LC/IR measurement, the 11210 has a unique function that detects partial discharge (PD) or flashover that may have occurred inside the insulation material during the high voltage insulation testing process. With PD detection of the battery's internal status before electrolyte filling, defective products can be filtered out before entering the next stage of production preventing the potential hazards that may occur in the field. In contrast to traditional methods of insulation test, Chroma 11210 provides an entirely new concept for inspection and evaluation of battery quality.
