3. Available Electrochemical Sensors For ToxiRAE Pro
The following sensors are available for use in the ToxiRAE Pro.
Note:
When replacing a sensor (even with the same type), the sensor may require
conditioning before first use, in addition to typical warm-up time prior to normal
operation. This can take from a few minutes to 24 hours, depending on the type of sensor.
Refer to RAE Systems Technical Note TN-151 for information on electrochemical sensor
replacement and maintenance.
