Dropping Point Tester

Introduction

Dropping Point Tester is a specialized laboratory instrument designed to determine the dropping point of lubricating greases. This crucial parameter signifies the temperature at which the grease undergoes a transition from a semi-solid to a liquid state. Operating on the principle of heating a sample and observing the point at which a standard cone penetrates the softened grease, the tester ensures precise measurement of dropping points. Widely used in industries like automotive and machinery, this tester provides essential information about the temperature range within which a grease can effectively lubricate moving parts.

Standards

ISO 2176:1995-Petroleum products-Lubricating grease-Determination of dropping point

ASTM D566-17-Standard Test Method for Dropping Point of Lubricating Grease

Complies with the above standards, but is not limited to them.

Features

1. Compact design and simple operation suit routine use.

2. Multiple sample positions allow simultaneous comparison.

3. Clear display or magnified view shows the melting transition.

4. Precise temperature ramp and detection give repeatable points.

5. Automatic detection reduces operator judgement.

FAQ

What is the Dropping Point Tester mainly used for?

The Dropping Point Tester is used to determine the melting, softening or dropping point of substances, supporting identity and purity checks. It is used in chemical, pharmaceutical, polymer, food and quality-control laboratories.

What standards does the Dropping Point Tester comply with?

The instrument is designed with reference to applicable pharmacopoeia, ISO, ASTM and GB/T methods for melting or softening point and IEC 61010 electrical safety. Procedures must follow the relevant method. Compliance documentation can be provided on request.

What does the warranty cover?

The system is covered for 12 months after shipment, including the main mechanism and electrical controls. Replaceable consumables and routine service items are not part of the warranty. Faults caused by improper installation outside the manual or unauthorised modification are not covered.

Will staff need special training?

Routine operation is straightforward and is covered in the user manual, including setup, daily use and basic maintenance. Staff with basic laboratory experience can run it after a short familiarisation. We provide remote guidance and can arrange on-site training where required.

What is the typical lead time for order delivery?

Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.

How often should the Dropping Point Tester be calibrated?

To protect result reliability, periodic verification should be performed, typically once or twice a year. The instrument arrives factory-calibrated, and self-check routines help spot drift. We offer traceable calibration service if the site needs it.

Are consumables and spare parts easy to obtain?

Filters, seals, probes and similar items are standard and can be supplied through our channel. Customers may also source equivalent items that meet the specification. Provide the model and serial number to confirm compatibility before ordering.

Are options or configurations available?

Yes, common options include different ranges, voltages, accessories, interfaces and capacity or size configurations. We confirm feasibility, specifications and any delivery impact before order confirmation. Custom requirements are reviewed case by case.

Do you provide on-site installation?

Most models can be commissioned by following the manual, including positioning, connections, checks and a first test run. Remote guidance is available during start-up. On-site installation, commissioning and training can be arranged separately where required.

What maintenance and safety points matter?

Do not use contaminated or overfilled capillaries, heat too quickly or skip temperature calibration. Prepare samples consistently. Follow the operating instructions.
