YRH.350 Ex Industrial Thermal Imager

The YRH.350 is an intrinsically safe Ex-rated industrial thermal imager designed for harsh and hazardous environments.
It features a rugged 2 m drop-resistant design, advanced 160×120 infrared detection, a built-in 3.2 MP visible camera, and a bright 3.5” colour touchscreen.
With IP54 protection, coal-mine intrinsic safety certification Ibi T4 Gb, and extensive temperature measurement tools, it is ideal for electrical inspections, petrochemical sites, mines, mechanical diagnostics, and maintenance teams requiring safe operation in explosive atmospheres.

Key Features

  • 160 × 120 uncooled FPA detector
    (Product title section shows “384 × 288”, but the technical table confirms 160 × 120 as the actual sensor resolution.)

  • 3.2 MP visible camera with dual LED lights

  • 3.5” TFT LCD touchscreen (640×480)

  • 2 m drop resistance (IEC 60068-2-32)

  • Audible + visual temperature alarms

  • 60-second voice annotation

  • Various lens options

  • Free professional analysis report software

  • Intrinsically safe explosion-proof rating: Ibi T4 Gb

How It Works / Overview

The YRH.350 uses a high-sensitivity uncooled FPA detector operating in the 8–14 μm long-wave infrared band to measure and visualize temperature differences on electrical, mechanical, and industrial assets.
