Enviro Technology Services (ET) partnered with california Nikira Laboratories, to provide the UK and Irish markets with access to a range of next-generation, highly portable optical extinguishing analyzers that meet a wide range of visibility and aerosol monitoring applications.

Nikira OEA-532 merged open path cavity ring measurement with their unique and patented self-referencing system to create optical extinction / visibility in the air analyzer with unmatched precision, negligible sample handling and minimal or no drift. This analyzer has many applications and has been widely used in airports, roads, tunnels, air quality and pollution monitoring networks, forestry, aerosol research and for manufacturing and research into clean rooms and semiconductors.

The versatile and portable OAS-532 is lightweight (7.7 kg) and compact (49 x 33 x 18 cm) and housed in a strong, durable and water-resistant Pelican case. The low power consumption (35 watts) allows the OAS-532 to operate on battery power for long periods of time in places where mains power is inaccessible. This analyzer includes built-in data storage for up to 2 years of continuous use. The data can be accessed via a USB connection or remotely with a cellular modem. This single wavelength analyzer (532 nm) is available in two formats: a standard 1 Hz version or an ultra-fast 10 Hz version suitable for eddy covariance applications, model OEA-532EC.
