UltraTrace 3000 FAQ

We have four units of the UT3000 ppb O2 analyzers and these require instrument air (50-60 psig) to activate the valves. Based on previous conversations with TAI we can use a Nitrogen in cylinder to activate the valve. If this is the case, what is the consumption Nitrogen in cylinder per month?

We decided to use manual calibration without the solenoid/pneumatic valves, with manual valves installed outside the analyzer for calibration, what would be the procedure on the wiring to de-activate the autocal function for this purpose?

For additional questions, please contact Technical Support​​.


Q: ​We have four units of the UT3000 ppb O2 analyzers and these require instrument air (50-60 psig) to activate the valves. Based on previous conversations with TAI we can use a Nitrogen in cylinder to activate the valve. If this is the case, what is the consumption Nitrogen in cylinder per month? 

A: These valves are activated by the pressure. The gas does not flow. In other words, if everything is leak tight, it will not consume gas out of your cylinder. Nothing is perfect of course and eventually you will need to replace the cylinder. But one cylinder should last for many months. The pressure stated is too low though. You would need between 70 and 120 psi. ​

Q: ​We decided to use manua​l calib​ration without the solenoid/pneumatic valves, with manual valves installed outside the analyzer for calibration, what would be the procedure on the wiring to de-activate the autocal function for this purpose? 

A: This analyzer had the calibration box side by side with the pneumatic valves. All you need to do is feed straight to the analyzer and not through the calibration box. 

There will be no complications if you just feed the gas straight to the analyzer and not the cal box. Just make sure the right gas is fed to the analyzer during calibration. ​
