AlphaLab USB-DL1 | USB Data Logger | 24-bit ADC, 10 µV Resolution
The AlphaLab USB-DL1 is a 24-bit analog-to-digital converter that logs voltage to a computer over USB. It can record the analog output of AlphaLab meters or act as a standalone logger for your own application, with unlimited data imported to spreadsheets and a live on-screen readout. It does not provide galvanic isolation, so readings are not accurate if the source shares a mains supply with the computer.
Key features
- 24-bit ADC with resolution down to 10 µV
- Optimised for precise DC signal collection; single-ended input accepts positive and negative signals
- Sample intervals from 250 ms to 30 s in 9 steps, plus PC-controlled single sample mode
- 1/8 in input connector; available with a cable for AlphaLab meters or with tinned leads
- Works with AlphaApp and C/C++ drivers; powered from the USB port
