Description
Whether in laboratories, workshops or on-site, the model CTB9350-165 micro calibration bath can meet any calibration requirement. This micro calibration bath can be used in the range -30 ... +165 °C [-22 ... +329 °F], not only covering the conventional functions.
In dry-well temperature calibrators, as a result of their low insertion depth and the resulting heat conduction errors, short probes lead to a significant increase in measurement uncertainty. Even when comparing the test items with an external reference thermometer, they cannot be too short. If the stem length is very short, a micro calibration bath is definitely preferable to a temperature dry-well calibrator.
If several probes are to be calibrated at the same time, the micro calibration bath has additional advantages: Thermometers with differing stem diameters can be calibrated together, without the need to provide exactly the correct inserts.

This approach is particularly useful for on-site calibration, when there is a wide variety of test items and their stem diameters are either varied or unknown.
The CTB9350-165 can be fitted with an integrated measuring instrument. This enables the measurement of resistances, thermoelectric voltages and also current signals of thermometers with a 0/4 ... 20 mA transmitter and their direct display in the selected unit.
It is operated via a large colour touchscreen. Test tasks can be created and automated via the user interface, saving the user a lot of time. Operation is intuitive and fast.
Special features
- Easy operation via intuitive, user-friendly menus
- Large, easy-to-read touchscreen
- Short response times due to optimised control
- Multi-function instrument with four controller parameter sets
- Creation of calibration tasks incl. preparation of a certificate

| probe basket for tank Angled probes, large-diameter probes or probes with special designs cannot be calibrated with a dry-well calibrator. For these applications, micro calibration baths have a great advantage. They feature a liquid tank.The liquid in the tank is circulated using a magnetic stirrer, and thus provides very good temperature distribution within the bath.The insert for liquids enables easy replacement and cleaning of the instrument.The liquids used are selected depending upon the desired calibration temperature. | Insert for liquids and |
