Factory Calibration and Service
In-House Factory Calibration
Factory calibration of In-Situ instruments should be performed every 12 to 18 months, or at any point when the data appears
to drift significantly. Factory calibration includes a thorough cleaning, all operational checks, necessary firmware upgrades,
O-ring replacement, and full range calibrations of the pressure sensor, temperature sensor, and conductivity sensor (when
applicable).
Return Materials Authorization (RMA) Form
To obtain a factory calibration, fill out and return the online Return Materials Authorization (RMA) form located at www.in-
situ.com/ .
Obtaining Repair Service
If you suspect your system is malfunctioning and repair is needed, you can help assure efficient servicing by following these

the malfunction.
3. If Technical Support determines that service is needed, they will ask your company to fill out the RMA form and
pre-approve a specified monetary amount for repair charges. When the form and pre-approval is received,
Technical Support will assign an RMA (Return Material Authorization) number.

Technical Support states otherwise.
