The SB989 is one device that can do these things but there many many others out there.
Although it is significantly more money I like some of the features like PC logging and the DC-DC regenerative discharge feature of the PowerLab 6 and 8 if you are going to be doing lots and lots of battery testing ... but if it is a rare thing once every year or two ... you probably won't need anything that expensive.
