THe 3300T sereies is a range of percent of Trace and Percent Oxygen Analyzers from Teledyne that offers two field configurable ranges and a calibration range, as well as two fully programmable low or high concentration alarms. The series has two ranges that measure at a standard 0-100 and 0-1000 ppm. It has a 0-25% calibration range, and displays its values on a 4-digit LED.
The 3300TA panel mount or 3300TB wall mount has quick and long lasting, fuel cell that can operate in various background gases such as hydrocarbons. It has a 0-10 VDC output that delivers range identification while the oxygen concentration is produced at 4-20 mADC and 0-10 VDC negative ground signals.
