FAQ

What is the Dean & Stark Water Content Tester mainly used for?

The Dean & Stark Water Content Tester is used for a defined laboratory measurement, preparation or processing task. It supports analytical, quality-control, research, clinical or industrial work where consistent, repeatable results are required.

Which standards and regulations apply to the Dean & Stark Water Content Tester?

The instrument is designed with reference to IEC 61010 electrical safety, the applicable international standard for the measurement or process and relevant GB/T standards. Procedures should 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.

How easy is the Dean & Stark Water Content Tester to use?

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.

How long does delivery usually take?

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 Dean & Stark Water Content Tester be calibrated?

The unit is calibrated and tested before delivery. For ongoing accuracy, verify it against traceable reference standards every 6 to 12 months, or according to the laboratory quality schedule. We can arrange calibration service and certificates where required.

Are the consumables universal or proprietary?

The instrument uses standard, widely available consumables rather than special locked items. Replacement parts, accessories and consumables can be ordered from us against the model number. We keep common service parts in stock for prompt supply.

Can the Dean & Stark Water Content Tester be customised?

A range of options is available to match the application, such as alternative settings, fittings, data outputs or power supply. We confirm each option and its effect on price and schedule up front. Larger custom builds can be discussed.

How is the Dean & Stark Water Content Tester commissioned?

Benchtop and standard units typically require only placement and connection before use, while larger systems may need professional commissioning. We confirm the installation requirements at order stage. On-site service and training can be provided if needed.

What maintenance and safety points matter?

Do not use the instrument outside its rated range or intended samples, skip calibration or ignore safety and maintenance instructions. Follow the operating manual and laboratory safety rules.
