How to Replace the PTU Module

The Orion Weather Station has a Pressure, Temperature, Humidity (PTU) module that can be replaced in the field with virtually no down-time. Electronic measurement equipment can drift in accuracy over time.

For many applications, this minimal drift is acceptable. But for some regulatory-compliant or very sensitive applications, customers can ensure factory-calibrated accuracy by replacing the PTU module per the manufacturer’s recommendation every two years. Each replacement PTU module comes with a factory calibration certificate.

Examples of customers who replace their PTU module regularly include energy companies like Alliant and Dominion, Los Angeles County Sanitation Districts wastewater treatment facilities, and Ford Motor Company Proving Grounds.

Watch this quick new video tutorial that demonstrates how to easily replace the module.
