Services include repair and NIST-traceable calibration of Evergreen Telemetry products. Only Wireless Sensing Modules are calibrated. The Wrist Reporter is a digital device optimized for display and storage, it has no role in measurement. However, it is advisable to submit the Wrist Reporter along with the Sensing Modules so its software can be updated.
Shortridge Instruments ADM’s and HDM's are calibrated for pressure, temperature, velocity, and airflow. Readings at setpoints are compared to NIST-traceable standards. No adjustments or repairs are performed.
The key calibration tool is the Setra 869, the most accurate low-pressure calibrator in the world. The Setra 869 boasts an accuracy of +/- 0.0002 in wc for its lowest range. For velocity and flow tests, our VFD-controlled fan serves three test stations through more than 60 feet of duct with flow straighteners and orifice plates. See the nearby table for nominal test points.
Additional test points may be added for a small fee.
Instruments will spend less than two business days at Evergreen Telemetry. For instance, if received on Monday, we will ship by Wednesday at the latest. If we miss that milestone, the calibration service fee will not be charged.
