Product details

SM-500

The SM-500/RME-O3 is a new and improved Calibrated Digital Ozone Sensor Module in a compact form factor!

The SM-500 is a calibrated ozone sensor instrument that utilizes a state-of-the-art electrochemical (EC) ozone sensing element. The SM-500 can be paired seamlessly with Eco Sensors’ OS-4 & OS-6 ozone controllers or it can be configured as an independent digital ozone instrument via RS-232 or USB serial communication.

The SM-500 includes a user-replaceable calibrated sensor module (RME-O3) that enables users to easily maintain calibration requirements for their application.

This technology from Eco Sensors provides accurate ppb-level detection and resolution over a wide (0.03-20 ppm, or 1-50 ppm) concentration range. The sensor module is compensated for temperature and humidity effects, with little to no cross sensitivity to VOC’s.

Typical Applications:

  • Laundries using ozone
  • Large noisy factory environments
  • Casinos and other ozonated public areas
  • Agricultural/cold storage areas
  • Farms
  • Food processing plants

Features:

  • 30 ppb lower detection limit with 5 ppb resolution
  • Integrated re-zero button
  • Choice of two operating ranges (0-20 ppm or 1-50 ppm)
  • Electrochemical Sensor
  • Wide detection range
  • Wide power supply range: 5-30 VDC (< 100 mA)
  • USB power and communication option included
  • RS-232 communication option included
  • Low Power
  • Low Maintenance
  • Small enough to mount almost anywhere
