DI-158 Data Acquisition Starter Kit
This data logger is manufactured in the United States of America


DI-158 products break new ground in price and performance, offering advanced features and options usually reserved for more expensive instruments. A channel scan list, high sample throughput rates, and an advanced computer interface are just some of the features combined to produce a robust instrument that can be applied to nearly any data acquisition situation where low and high level signals need to be acquired to a PC.

The high level gain/high full scale range option provides gain ranges of 1, 2, 4, 8, 16, 32, 64, 128, 256, and 512 with a full scale range of ±64 volts. The standard model provides gain ranges per channel of 1, 2, 4, and 8 with a full scale range of ±10 volts. Units are powered through the USB interface so no external power is required.
