PAT-Tester-x-8
Fully featured potentiostat / galvanostat / impedance analyzer with up to 8 channels for small-scale and special-purpose testing.
The individual test solution
The PAT-Tester-x-8 is the perfect choice for small scale and special purpose testing. It brings the same battery tester hardware and software as the PAT-Tester-i-16. However the test channels are separated into individual devices, the so-called PAT-Channel-1. Each PAT-Channel-1 features a fully equipped galvanostat / potentiostat / impedance analyzer. Up to 8 PAT-Channels may connect to one single PAT-Controller-8 which serves as the control unit for storing all measurement data and enabling communication with the EL-Software server. That way each channel of the PAT-Tester-x-8 can be controlled from any client PC in the same network via the EL-Software.
The individual PAT-Channels can be placed where they are needed: on the bench, in a climate chamber, or inside the glove box. While tailored for PAT-Cells, each PAT-Channel-1 can also connect to almost any other test cell including the ECD dilatometer, optical ECC in-situ cells and all other small format cell (e.g. coin cells, pouch cells, T-cells).

EL-Software
EL-Software is the software platform to control all EL-CELL battery testers, be it single-channel or multi-channel systems. EL-Software is covering all test cases from strain measurements with the ECD dilatometer through simple cycle tests on a single button cell to high throughput material testing with the PAT system.
