HM-GS300 Food Safety Detector

Product Introduction

The HM-GS300 is an integrated food safety rapid detection instrument developed by HM Instruments (恒美智造) for comprehensive multi-category food quality screening. Built around a 24-channel optical detection platform with a 4-wavelength cold light source (410 nm, 520 nm, 590 nm, and 630 nm), the instrument supports optical path switching across up to 64 equivalent wavelengths, enabling precise absorbance measurements for a diverse range of analytes. With over 200 pre-programmed test items spanning 14 detection categories — including food additives, pesticide residues, veterinary drug residues, heavy metals, mycotoxins, and spoiled meat indicators — the HM-GS300 serves as a centralized testing workstation for food safety laboratories, regulatory inspection agencies, and food production quality control departments.

Powered by an ARM Cortex-A7 RK3288 processor running at 1.88 GHz, the instrument delivers fast data processing and responsive touchscreen operation on its 10-inch display. The onboard memory stores up to 200,000 test records, supporting traceability and audit requirements. The dual power supply design — AC mains operation with a built-in 6 Ah lithium battery — provides flexibility for both benchtop laboratory use and mobile field inspection.
