Thermometer & Temperature Data Logger
Measures temperature (thermometer) or records it over time (data logger). Used to check water baths, ovens, incubators, fridges, stability chambers and sample temperatures, and to map storage areas.

Viva questions
Think of your answer first, then open it to compare.
1. Describe a comparison calibration of a data logger.
Place the logger sensor and a calibrated reference thermometer side by side in a stable stirred bath or dry block at each test point. When stable, record both readings, apply the reference correction, calculate the logger error at each point and compare with the SOP limit.
2. A logger in a stability chamber shows a gap in its data. What do you do?
Investigate the cause (battery, memory, start settings), check other monitoring records for the gap period, assess impact on the stored samples, record a deviation as required and correct the cause, for example by replacing the battery and reviewing the logger schedule.
Keep every Thermometer / logger in control: usage logs, calibration and maintenance schedules, and automatic blocking of overdue instruments.
