TSI recommends that the HM685 Hydronic Manometer receive an annual
calibration. TSI will verify calibration of the instrument and re-issue a
certificate of calibration with traceability to NIST.
This “annual checkup”
helps to ensure the specified accuracy of the instrument is maintained.
To calibrate the instrument, please ship TSI the complete package that
includes the meter and accessory temperature probe. Everything should be
packed carefully within the carrying case and then inside a shipping box.
The original shipping box and packaging (carton and foam) is preferred.
Before returning the Hydronic Manometer to TSI for service, visit our
