Product Description

The SER8CH-HLF-1in is an 8 channel, 24 bit realtime continuous data acquisition system with a low power consumption of 10 milliamps. At only 1" wide x 3" long, it is well suited to many restricted space applications such as borehole monitoring.

The system is the ultimate in ease of use. Simply connect it to a RS232 port, provide power, and it is ready to communicate at 9600 baud. No device drivers or complicated software setup is required.

A full featured DVM acquisition and display program is included for GUI multimeter displays when desired. The software provided is supported under Windows 7/8/10 and Linux operating systems (32 + 64 bit).

Buffered full and half copies of the A/D reference voltage are available on the analog input header for ratiometric sensor applications and excitation. Samples at 1/2 Hz ( 2 second period ) from each channel with a full scale input voltage range of 0 to 5 volts.

The bundled "in the box" system comes with all the accessories you need to start acquiring data immediately. These include software, PDF User Manual, 9 VDC power supply, 6' RS232 serial cable, and header cables for analog input and power/RS232.
