| Kaye LTR-150 - Dry Block & Liquid Bath All-in-One Temperature Calibrator
Silicone Oil:
To achieve the best accuracy over the entire range -30° to 150°C it is recommend
using the Kaye 200 Silicone Fluid 10 CS or equivalent. (1 litre)
The calibration liquid (sold separately) is poured directly into the micro bath tub insert.
IMPORTANT NOTICE!
Only use clean calibration liquid. Over time repeated use of the oil can lead to a contamination of the
calibration liquid. This contamination can lead to smeary gel effect on the bottom of the tank due to
the rotation of the magnetic stirrers.
Clean the tub before calibrating sensors.
Exchange the worn magnet stirrer.
Exchange dirty, smeary calibration fluid.
Filling the Micro Bath
CAUTION! Risk of incorrect measurement or material damage!
Do not exceed the maximum fill level during operation!
• Above the maximum fill level, the heat dissipation is too great, preventing compliance with the
specified tolerances.
• Overflow of the calibration liquid causes contamination and can damage the calibrator.
Ensure that the maximum fill level is not exceeded during operation.
The fill level in the tub insert rises because of the following factors:
•
Thermal expansion:
Calibration liquids expand to varying degrees because of heating. The
increase in fill level depends the reference temperature setting.
•
Displacement by sensors:
The volume displaced by the sensors
being calibrated must be considered in the filling amount.
•
Rise due to stirring:
The rotation of the magnetic stirrer forms a
whirlpool in the liquid. This raises the fill level at the wall.
The maximum fill level with the tub insert is below the fixture for the insert
exchange tool.
The maximum fill level is ~0.32 litres.
