  • 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

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 Boundary

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

Resetting maximum-indicating liquid-in-glass clinical thermometers
Lowering the retained column before another measurement
Preparing samples before verification or calibration
Batch processing during production quality control
Preparing thermometers for repeated immersion tests
Routine handling of reusable glass thermometers where permitted

Equipment Limitations

Does not function as a general-purpose laboratory centrifuge

Operating Principle

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.

STEP 01
Reading Retained
The maximum-indicating structure holds the highest measured reading.
STEP 02
Centrifugal Force Applied
The equipment rotates the correctly loaded thermometers at the rated speed.
STEP 03
Column Returned
The thermometer is prepared for the next measurement or verification cycle.
Reset performance can vary with filling liquid, capillary design, retained reading, sample dimensions and loading arrangement. Inspect the liquid-column position after each cycle.

Thermometer Centrifuge FAQ

What is a clinical thermometer shaker used for?
A clinical thermometer shaker returns the retained liquid column of a maximum-indicating glass clinical thermometer to a suitable starting position. The KR-3C automates this preparation step before repeated measurements, verification, calibration or production inspection, reducing the repetitive manual shaking required when laboratories or manufacturers process multiple thermometers.
Which thermometer types are compatible with the KR-3C?
The KR-3C is intended for maximum-indicating liquid-in-glass clinical thermometers. It is not designed for digital, electronic, infrared or phase-change thermometers. Before ordering, customers should confirm the thermometer’s filling liquid, overall length, maximum diameter, bulb dimensions and construction so holder and loading compatibility can be reviewed.
Which standards are relevant to this clinical thermometer shaker?
The equipment can support sample preparation in workflows related to JJG 111-2019 and EN 12470-1:2000+A1:2009. JJG 111-2019 covers clinical thermometers within a 30.0°C–43.0°C measuring range, while EN 12470-1 addresses metallic liquid-in-glass clinical thermometers with a maximum-indicating device.
Does the KR-3C perform thermometer calibration or verification?
No. The clinical thermometer shaker only resets the retained liquid column and prepares samples for subsequent testing. It does not generate a reference temperature, measure indication error or provide pass/fail results. A complete verification arrangement normally also requires a calibration bath, reference thermometer, sample holder, reading device and documented test procedure.
How many thermometers can the KR-3C process per batch?
The specified maximum loading capacity is up to 60 thermometers per batch, with a rated rotational speed of 1,400 r/min. Actual loading suitability depends on thermometer dimensions, holder configuration and balanced-loading requirements. Customers should provide sample specifications before purchase rather than assuming every thermometer format can be loaded at the maximum capacity.
Can the glass thermometer shaker process mercury-free thermometers?
Potentially, but compatibility should be confirmed according to the filling liquid and thermometer construction. EN 12470-1 applies specifically to thermometers filled with metallic liquid, while national restrictions may affect mercury-containing products. Customers using gallium-based or other mercury-free glass thermometers should provide samples or detailed drawings for technical evaluation.
How does the thermometer shake-down machine reset the liquid column?
The thermometer shake-down machine rotates correctly positioned thermometers to generate centrifugal force. This force moves the retained thermometric liquid back through the capillary restriction toward the sensing bulb. Reset performance can vary with filling liquid, capillary design, retained reading, sample dimensions and loading arrangement, so the column position should be inspected after each cycle.
How is the KR-3C used in a verification laboratory?
The clinical thermometer shaker is normally used before immersion or indication-error testing. After inspecting and loading the thermometers evenly, the operator performs the reset cycle and verifies the resulting column position. The prepared thermometers can then be transferred to the calibration bath and evaluated against the applicable laboratory or legal-metrology procedure.
What information is required before ordering the KR-3C?
Customers should provide the thermometer type, filling liquid, overall dimensions, bulb dimensions, expected batch quantity and applicable standard or internal procedure. The destination power supply should also be confirmed. The standard electrical specification is AC 220 V ±22 V, 50 Hz ±1 Hz; alternative electrical requirements require confirmation before quotation.
What safety and maintenance checks are recommended?
Inspect thermometers for cracks, damaged bulbs or separated liquid columns before loading. Samples should be distributed evenly, and operators must wait until all rotating components stop before removal. Holders, cushioning materials, electrical controls and the power cable should be checked regularly. Unusual vibration or noise should be investigated before further operation.
