Safety  

 

Critical Operating Conditions 

-

 

Because the humidity sensor is exposed to moisture during shipping, the system must generally operate for a 

couple of days in a dry Nitrogen environment before the sensor dries out and delivers completely accurate 

readings.  

-

 

Never use this equipment with gases that are non-compatible with the materials of the construction. This may 

cause damage to equipment or injury to personnel.  

-

 

This instrument contains electronic components that are susceptible to damage by static electricity. Proper 

handling procedures must be observed during the removal, installation or other handling of internal circuit boards 

or devices.  

-

 

Do not release toxic or flammable gases in the vicinity of personnel. Be sure that venting and disposal methods 

are in accordance with Federal, State and local requirements.  

-

 

If toxic or flammable gases are used with this equipment, emergency equipment applicable to the gases in use 

should be available in the operating area.  

-

 

Sensors and controllers are factory calibrated to operate at the pressures specified with the order. Attempts to 

operate them under conditions different than ordered may result in less than desirable performance or may cause 

the unit to fail to function.  

-

 

The air must be completely turned off before any adjustments are made to the controller or else the readings will 

be inaccurate. 

-

 

The Nitro-Watch™ draws its power from the Dual Purge System and will not operate unless the Dual Purge 

System is plugged in and turned on.
