Hi and thank you for your post.
There a number of options really, we have 2 loggers that can do this range:
The USB TC08, this is an 8 channel Thermocouple data logger
Also we have the PT104, a serial ported device that can take up to 4 Platinum resistance thermometers.
These units can also act as voltage loggers, USBTC08 can measure +/-70mV and the PT104 can measure 0 - 2.5V.
We also have other voltage logging devices like the ADC11, which has 11 channels and measures 0-2.5V.
What kind of voltages are you trying to measure?
