Overview

The Chemtrac UVP1000 Portable Organics Monitor is a compact and rugged device designed for quick and accurate field testing of UV 254nm. It provides measurements in both UV transmittance (UVT) and UV absorbance (UVA) within minutes, making it ideal for water analysis in various environments. The monitor features a 254nm wavelength UV light source and requires no reagents, significantly reducing operational costs compared to other UV254 analyzers.

Key features of the UVP1000 include a simple one-minute warm-up time, a user-friendly interface, and easy calibration with the push of a button. The device is equipped with a low-pressure germicidal UV lamp and a 10 mm x 10 mm quartz cuvette sample cell, ensuring high accuracy and reliability. It displays results on a 32-character backlit LCD screen, which provides clear instructions and system messages.

The UVP1000 is highly versatile, suitable for applications in water treatment, distribution system monitoring, and wastewater treatment. It can detect changes in coagulant demand, monitor organics removal, and identify potential disinfection byproducts (DBPs). The monitor is housed in a watertight and dust-proof enclosure, weighing just 4 lbs, and can operate in temperatures ranging from 32°F to 122°F (0°C to 50°C).
