The UV500 is an on‑line water analyzer with a high‑resolution 2048‑pixel UV‑visible spectrograph (180–750 nm) enabling simultaneous multi‑parameter monitoring (COD, BOD, TOC, NO₃, PO₄, colour, turbidity, Cr VI). Optional UV‑visible fluorescence for PAH detection, integrated nephelometric turbidity via laser diode, and a xenon flash lamp rated for &gt;10⁹ flashes with automatic acid‑based cleaning ensure reliable, low‑maintenance operation in wastewater treatment, river monitoring, and chemical process control applications.

The UV300 is a cost-effective online water analyzer focusing on one or two parameters. Based on stable UV-visible spectroscopy it measures organic matter, nitrate, colour, and PAH, with an optional colorimetric module for PO₄, Cl₂, NO₂, Fe, and Al and a laser‑diode turbidity sensor. External probes support pH, ORP, dissolved oxygen, and conductivity. An automatic acid‑cleaning system and long‑life xenon lamp minimize maintenance, and a web‑based interface enables remote control and troubleshooting.

HT-110 is an on-line total organic carbon (TOC) analyzer designed for pharmaceutical-grade water systems. It employs a continuous UV oxidation and conductivity detection method, requiring no reagents or carrier gases, and offers high repeatability (±2% F.S.) in low-concentration ranges (0–100 ppb). Built-in deaeration suppresses bubble-induced errors, while external contact input allows remote ON/OFF control. Extended UV lamp lifespan enables annual maintenance.

Field-Installation Ammonia Nitrogen Analyzer

The GX-100 is a modular water quality monitoring system tailored for drinking water regulation compliance. It measures seven essential parameters—turbidity, color, free residual chlorine, pH, conductivity, water pressure, and water temperature—using detachable sensor modules for rapid on-site maintenance and stable, continuous performance.

GX-100

The EL200 is a rugged, modular water quality controller capable of handling a wide range of probes for measuring key parameters such as pH, ORP, dissolved oxygen, conductivity, chlorine, turbidity, TSS, and temperature—all within a weather-resistant enclosure for field and process environments. It features intuitive touch-screen control, multi-channel flexibility, and both local and remote interface options.
