This document describes the features and characteristics of RAE Systems 7NO-250 sensor, including detection range, maximum detection concentration, sensitivity, baseline current, baseline drift, resolution, response time, linearity, and long-term stability.
The 7 NO-250 is a nitric oxide (NO) sensor produced by RAE Systems. It is designed for detecting NO concentrations in air and reports values in parts per million (ppm). The manual includes key performance data, environmental limits, and contact information for the manufacturer.
The document lists the sensor's measurement range, temperature and humidity limits, pressure range, detection limit, and typical output signal. It also presents baseline drift and temperature‑dependence graphs to help users understand sensor behavior under varying conditions.
