Curing tank calibration procedures
Instrument qualification (DQ · IQ · OQ · PQ)
- 01
DQ — Design qualification
Specifies capacity, set point and tolerance (e.g. 27 ± 2 °C), heating and cooling capacity, circulation and data logging.
- 02
IQ — Installation qualification
Confirms the tank is installed on a suitable floor with drainage and safe electrical supply, and records equipment IDs.
- 03
OQ — Operational qualification
Maps water temperature at several points across the tank, empty and loaded, and checks controller accuracy and alarms.
- 04
PQ — Performance qualification
Trends daily temperature records and shows the tank stays within tolerance in routine use across seasons.
Keep every Curing tank in control: usage logs, calibration and maintenance schedules, and automatic blocking of overdue instruments.
