Arbin HPS with Integrated Chamber Option
The HPS is Arbin's flagship laboratory battery tester, delivering 10 ppm voltage measurement precision and 20 ppm current measurement precision via a 24-bit DAC/ADC architecture across six current ranges per channel. Built-in EIS (10 mHz – 1 kHz), DCIM, self-discharge current measurement, and PT100 temperature sensing make it ideal for high-confidence Coulombic efficiency studies. The integrated thermal chamber version adds per-channel temperature-controlled cell fixtures, while the standalone chassis allows flexible external chamber pairing. Both configurations support rack mounting up to six channels
