2B Tech’s original single channel EPA-certified Federal Equivalent Method (FEM) ozone monitor. The Model 202 was first manufactured in 2002 and features real-time ozone measurements produced every 10 seconds. Robust and versatile ozone monitor used for a variety of ambient ozone monitoring applications.

• 0-250 ppm with 1.5 ppb precision
• EPA-certified FEM (EQOA-0410-190)
• Highly portable, low power, benchtop ozone monitor

Overview

• FEM single beam (UV-based) ozone analyzer; accurate and precise ozone measurements
• Lightweight with low power consumption and a quiet, long-life internal air pump
• Applications include ambient monitoring in remote locations where power is limited; vertical atmospheric profiling; urban arrays of ground-based ozone monitors; personal exposure monitoring; laboratory studies

Features

• Ozone measured 0-250 ppm by UV absorption at 254 nm, single beam
• Quiet long-life internal air pump (now standard)
• Low power consumption (~7.2 watt)
• Internal data logger (EEPROM), logs 16,383 lines of data
• Real-time clock
• Both serial and user-scalable analog voltage outputs (4-20 mA current output optional)
• Flash card memory (SD card) for virtually unlimited, portable data storage
• Three 0-2.5 VDC analog inputs for logging other measurements, such as external temperature, pressure, and humidity
• Convenient user interface to microprocessor, including calibration parameters (gain and zero)
• Selectable measurement time of 10 s or data averaging times of 1 min, 5 min and 1 hr (custom averaging times available)
• DewLine™ for elimination of any water vapor interference, a unique feature of 2B Tech instruments
