Product information

Overview

The U9601 Series is an ultra-compact, high-performance optical refrigerant leak detection sensor developed by Unitense. Based on Non-Dispersive Infrared (NDIR) technology, it is specifically engineered for OEM integration into modern HVAC&R systems, heat pumps, and chillers operating with next-generation low-GWP and natural refrigerants.

Key Features & Technical Advantages

  • Broad Gas Detection: Pre-calibrated for mildly flammable A2L refrigerants (R32, R454A, R454B, R454C) and flammable natural refrigerants (R290 Propane).

    • Outstanding Accuracy & Stability: Standard measurement range of 0–50% LFL (customizable to 100% LFL) with ±3% LFL accuracy, long-term stability within ≤2% LFL, and fast response time (<30 seconds).
