IEC 61010-2-020 Thermometer Centrifuge for Glass Clinical Thermometers
The IEC 61010-2-020 Thermometer Centrifuge uses centrifugal action to return the retained liquid column of maximum-indicating glass clinical thermometers to a lower starting position before reuse or verification.
- Primary Purpose: This Thermometer Centrifuge supports batch liquid-column resetting before repeated m easurement or verification.
- Suitable Samples: Liquid-in-glass clinical thermometers with a maximum-indicating structure.
- Typical Users: Metrology laboratories, thermometer manufacturers, inspection facilities and medical departments.
- Workflow Position: Sample preparation before calibration, indication-error verification or quality inspection.
- Equipment Boundary: The glass thermometer shaker resets the retained column but does not generate a reference temperature or measure thermometer error.
Thermometer Centrifuge Product Overview
IEC 61010-2-020 Thermometer Centrifuge for Glass Thermometer Resetting
Maximum-indicating liquid-in-glass clinical thermometers retain the highest measured temperature because a restriction between the capillary and sensing bulb prevents the liquid column from returning automatically after cooling.
Before the next measurement or verification cycle, the retained column must be returned to a suitable starting position. Manual shaking is repetitive and operator-dependent, particularly when a laboratory or manufacturer processes large batches.
The KR-3C is presented as an IEC 61010-2-020 Thermometer Centrifuge for motor-driven batch resetting of up to 60 thermometers. This dedicated Glass Clinical Thermometer Centrifuge, also described as a Clinical Thermometer Shake-Down Centrifuge, supports verification preparation, production inspection and repeated measurement workflows.

Application Scope and Limitations
The IEC 61010-2-020 Thermometer Centrifuge is intended for maximum-indicating liquid-in-glass clinical thermometers that retain their reading after removal from the measurement environment.
Suitable Applications
Equipment Limitations
Centrifugal Column Reset Principle
When a maximum-indicating clinical thermometer is heated, the thermometric liquid expands through the capillary restriction. After cooling, the restriction prevents the indicated maximum from returning freely to the sensing bulb.
The IEC 61010-2-020 Thermometer Centrifuge applies centrifugal force in the direction required to move the retained liquid back through the restriction. As a motor-driven Clinical Thermometer Shake-Down Centrifuge, the KR-3C replaces repetitive hand shaking with a defined rotational process.
Typical Operating Procedure
Before operating the IEC 61010-2-020 Thermometer Centrifuge, inspect the thermometers and arrange the samples according to the approved loading procedure.

Reference Standards and Verification Context
IEC 61010-2-020:2016
IEC 61010-2-020:2016 specifies particular safety requirements for electrically powered laboratory centrifuges and is intended to be read together with IEC 61010-1:2010.
The IEC 61010-2-020 Thermometer Centrifuge is used for a specialized laboratory centrifuging task: returning retained liquid columns in compatible glass clinical thermometers.
Any claim of full conformity or certification should be supported by the applicable product design review, safety test report and supplied compliance documentation.
JJG 111-2019 Clinical Thermometers
JJG 111-2019 applies to liquid-in-glass clinical thermometers with a maximum-indicating structure and a measuring range of 30.0°C to 43.0°C.
The IEC 61010-2-020 Thermometer Centrifuge supports column resetting and sample preparation within verification workflows based on JJG 111-2019.
The KR-3C is supporting equipment rather than a complete thermometer verification system. It neither generates a reference temperature nor determines indication error.
Typical Supporting Equipment
Typical Laboratory and Production Applications
Legal Metrology Laboratories
The IEC 61010-2-020 Thermometer Centrifuge prepares batches before verification, repeated immersion and indication-error testing.
Thermometer Manufacturers
An IEC 61010-2-020 Thermometer Centrifuge supports production inspection, sampling, final quality control and repeated performance testing.
Calibration and Inspection Facilities
The IEC 61010-2-020 Thermometer Centrifuge can work alongside a calibration bath, reference thermometer, holder and reading station.
Hospitals and Medical Departments
Where reusable glass thermometers remain permitted, the IEC 61010-2-020 Thermometer Centrifuge reduces repetitive manual shake-down work.
Operational and Procurement Value
For laboratories and manufacturers, the IEC 61010-2-020 Thermometer Centrifuge provides a dedicated solution for one clearly defined stage of the glass clinical thermometer workflow.
Batch Processing
The IEC 61010-2-020 Thermometer Centrifuge processes up to 60 compatible thermometers per batch.
Reduced Manual Handling
Motor-driven resetting reduces repetitive hand shaking during multi-sample preparation.
Controlled Preparation
A defined rotational process helps reduce operator-to-operator variation in preparation.
Dedicated System Role
The Glass Clinical Thermometer Centrifuge can serve as a stand-alone Clinical Thermometer Shake-Down Centrifuge or support a larger verification setup.
Configuration and Selection Notes
Before ordering the IEC 61010-2-020 Thermometer Centrifuge, confirm the thermometer construction, filling liquid, sample dimensions, applicable procedure and local electrical supply.
Thermometer Filling Liquid
Specify whether the samples contain mercury, a gallium-based metallic liquid or another thermometric liquid.
Sample Dimensions
Provide overall length, maximum diameter, bulb dimensions and thermometer construction.
Loading Arrangement
Confirm holder compatibility, cushioning needs and balanced-loading requirements for the intended batch.
Applicable Procedure
Identify IEC 61010-2-020, JJG 111-2019, EN 12470-1 or the relevant internal procedure so the IEC 61010-2-020 Thermometer Centrifuge can be reviewed within the complete workflow and the applicable standard boundary can be confirmed.
Power Supply

- Wait for all rotating components to stop before handling samples.
- Follow local mercury-control procedures where applicable.
Routine Inspection
- Check thermometer holders and cushioning materials.
- Inspect rotating components and electrical controls.

- Keep loading containers clean.
- Verify rotational speed according to the laboratory quality procedure.
Compliance & Regulatory Assurance
The KR-3C clinical thermometer shaker supports the liquid-column resetting and sample-preparation stages of verification procedures for maximum-indicating glass clinical thermometers. It can be used in workflows related to JJG 111-2019 and EN 12470-1, depending on the thermometer type, filling liquid, applicable test method and laboratory requirements.
Final compliance depends on the complete verification arrangement, including the calibration bath, reference thermometer, sample holders, reading equipment, operating procedure and applicable edition of the standard. The KR-3C is supporting preparation equipment and should not be represented as an independently certified verification or calibration system. Equipment documentation, speed records and traceability information can be confirmed according to project requirements.
