Arduino temperature datalogger with 4 channels

We desire to build a compact temperature datalogger for open-field works.
We are looking for the components project and material list; the assembly manual; and the programming.

Our prototype must have:
Temperature channels: 4 temperature probes (1m cable for each probe);
Temperature scale: Celsius (main scale) and Fahrenheit;
Temperature range: -200°C until 300°C;
Temperature step: 0,1 °C;
Accuracy: ±0,3 °C;
Sampling: Adjustable between 1s til 3600s (1h);
Storage: SD card;
Power: AA battery (enough to carry a 6h data sampling);
Display: With a size that we could see the temperature of each channel;
Weight: Under 700g
