The DPM‑111‑C2 is a highly sensitive digital picoammeter engineered for precision measurement of ultra-low DC currents, ranging from 10⁻⁹ A to 10⁻⁴ A across six decade ranges with 100% over-ranging capability Imimg+9Imimg+9Ses Instruments+9. It employs a low-noise AD549 FET-input electrometer amplifier, ensuring exceptionally low input bias current (~50 fA), minimal drift, and excellent linearity Ses Instruments+2Imimg+2Ses Instruments+2. This model includes a USB interface compatible with SES‑CAMM software (Windows‑based) for real-time data logging and PC control 4.imimg.com+1Ses Instruments+1. Readings are displayed on a 3½‑digit LED panel, with auto polarity detection and direct measurement of either current direction SVS Labs+8Imimg+8Ses Instruments+8. Ideal for applications involving photomultiplier tubes, leakage currents in semiconductors or FETs, high-resistance materials, piezoelectric sensors, and precision air conductivity measurements |
