Why We Test Every Module — Not Just Look at It
In the surplus market, "tested" is a word that gets stretched. We define it clearly for the ICS Triplex T3431-IM: power-up on a live ICS Triplex rack, all channels exercised with calibrated sources, communication ports verified, 48 hours of continuous operation at 55°C. A printed test report with serial number, test date, and measured values accompanies every shipment. This is what real testing looks like — not a visual inspection, not a "light comes on" check.
Factory-sealed. Genuine ICS Triplex with full traceability. 12-month warranty. Ships within 24 hours from Shenzhen via DHL, FedEx, or UPS.
Compatible Parts — Same System
These modules share the same system family as the T3431-IM. Commonly ordered together for complete rack builds or spare parts kits.
