The SM50 ozone sensor circuit provides ppb level ozone measurement in a flexible cost effective package. Each module is factory calibrated and ready to use with a multi-point calibration (NIST traceable).
Outputs include analog voltage, relay and status indicators with optional RS232 or RS485. Standard inputs include dipswitch settings for the relay and calibration buttons. Optional inputs include two analog voltages and two x GPIO which can be used to connect a temp/RH sensor.
Pre-loaded firmware gives access to proprietary algorithms developed by Aeroqual to optimise measurements and enhance data output. The firmware can be adjusted to trigger an alarm above or below a user selected setpoint, or to control output to stay within +/-10% of the setpoint.
For selected partners we can customise the SM50 ozone sensor circuit specifically to your requirements and can provide specialist design input on how to take the best possible measurements for any given application.
