Smelting Sensors · Since 1989
Full range of 602 / 604 / HR / OR probe heads with S / R / B / W calibration options — success rate >98%, response in 2-5 seconds, compatible with all temperature lances.
Wireless · No Compensation Wire
Temperature data transmitted wirelessly to furnace-side displays and office systems — 300 m or more in open areas, completely free from cables for flexible layout.
Cast Iron Thermal Analysis
Automatically measures C%, Si% and CEL within 1-2 minutes of pouring — industrial PC with 15-inch LCD, fast, simple and accurate.
Furnace-side Display
3½-digit 5-inch high-brightness red LED, S / R / D / B calibration for rapid measurement, 200-test history, centralized multi-station monitoring.
Product System
From furnace-side probes and samplers to workshop displays, from portable checks to molten iron composition analysis — the full chain of smelting measurement.
Fast thermocouples, fast samplers, thermal analysis cups and industrial thermocouples — accurate data within seconds of immersion.
Large-screen pyrometers, portable melting thermometers, wireless lances and molten iron thermal analyzers — every heat's temperature and composition, clearly visible and traceable.
Featured Products
Field-proven products refined over three decades, 100% inspected before shipment.
XQY-RQC Series
Round cup (XQY-RQC): measures carbon equivalent, carbon and silicon content in about 60 s with a thermal analyzer; supports undercooling, nodularity and more for foundry furnace-front control.
Series 602 / 604 / OR / HR
Consumable lance probe for furnace-side temperature. All calibration types S/R/B/C/D, configurable tip, precision and paper tube length for BOF, EAF and LF refining.
