River ecosystems are integral to sustainable environmental development, playing a crucial role in understanding suspended solid matter (SSM) transport dynamics and soil conservation. Accurate monitoring of SSM concentrations watersheds is foundational for these studies. This research introduces evaluates novel HHSW·NUG-1 photoelectric sand meter, specifically designed measurement. Its reliability was validated at three hydrological stations, including Xiaolangdi. The instrument, based on light scattering principles, optimized environments with high loads rapid flow rates. Laboratory tests indicate measuring range 0 730 kg/m3, field trials show effective operation within 375 meeting the needs stations. Through comparative analysis measurement data, we established conversion relationships various concentration ranges, confirming that instrument’s system error less than 1%. meter adheres standards outlined “Guidelines Test Rivers”, demonstrating stability reliability, calibration methods, observation accuracy, real-time monitoring, data storage, continuous operation. For optimal use, adherence relevant instrument recommended, particularly stations requiring analysis. Standard sampling coefficients should be conducted, proper sensor installation avoid interference from conditions. In conclusion, optoelectronic exhibits stable reliable performance practical applications, broad potential deployment other river
