【English Version】SIR-800 Infrared Thermometer Introduction
The SIR-800 Infrared Thermometer is a non-contact temperature measurement device developed with advanced sensing technology, designed for multi-scenario temperature monitoring requirements. By capturing infrared radiation energy emitted from object surfaces, it enables fast and safe temperature data acquisition, suitable for industrial maintenance, equipment inspection, environmental monitoring, and daily health management.
Equipped with a high-sensitivity optical sensor, the device features adaptive adjustment within 0.3 to 1.0 emissivity range to ensure measurement accuracy across various material surfaces. With a broad measurement range from -50℃ to +800℃ and 0.1℃ resolution, it achieves ±1.5% accuracy under normal operating conditions. The integrated laser targeting system supports both single-point positioning and area scanning modes, enhancing target acquisition efficiency in complex environments.
User-centric design elements include a 3.5-inch LCD backlit display with digital/analog dual display modes, ensuring clear readability under strong light or dim conditions. The built-in data storage module records up to 50 recent measurements, complemented by a USB-C universal interface for convenient data export and analysis. An ergonomic grip with anti-slip texture provides comfortable handling during prolonged operation.
Safety features comply with IP54 protection standards, offering resistance to dust ingress and accidental water splashes. The intelligent sleep function automatically reduces power consumption during inactivity, working in tandem with replaceable lithium battery packs to deliver up to 8 hours of continuous operation per charge. A multi-stage temperature alert system activates audible-visual warnings when detected values exceed preset thresholds, delivering effective early warning for industrial safety and health monitoring scenarios.
