DC 0-1V to 0-10V voltage amplifier
Not to be too judgmental, but that's a pretty crappy data logger (10 bits). 

A simple gain of 10 amplifier will do it. 10 bits with 1V input means that 1 bit is (input referred) 1mV so a single-supply op-amp with an offset voltage &lt;&lt; 1mV will not add significant error. I put a pretty good one in there, but even an LM324 won't typically be all that bad (maybe one bit). Similarly the resistors R1 and R2 should have a ratio that's within (say) 0.05% to not add much error, but using 0.1% parts won't add much error typically, or even 1% and adjust for the error digitally or with a trimmer. R3, R4 can be 1% or 5% and C1-C3 can be X7R ceramic.
