Calibration
Annual recalibration of the SF82 is recommended to maintain the performance. Calibration
services traceable to the UK National Physical Laboratory (NPL) and the US National Institute of
Standards and Technology (NIST) are provided by Michell Instruments.
Michell Instruments offers a variety of re-calibration and exchange sensor schemes to suit specific
needs. A Michell representative can provide detailed, custom advice (for Michell Instruments’
contact information go to www.michell.com).
Sensor Guard Replacement
The sensor is supplied with a white HMWPE guard (standard) or a stainless steel guard (if
specified at time or order).
The sensor guard should be replaced if the surface shows any damage or signs of discolouration.
When replacing a guard, make sure to wear clean disposable gloves, and handle by the threaded
base section only.
Replacement HMWPE or stainless steel guards can be ordered from your Michell Instruments
representative.
Bonded Seal
If the supplied bonded seal is damaged or lost, a pack of 5 replacement bonded seals can be
obtained by contacting your Michell Instruments representative.
O-ring Seal
