Engler Viscometer

Introduction

An Engler viscometer is used to measure viscosity of petroleum products based on flow time comparison with water. It is widely used in oil testing laboratories. The system provides standardized viscosity measurement for quality control and industrial applications.

Standards

ISO 3219:1993-Plastics-Determination of viscosity using a rotational viscometer with defined shear rate

ASTM D2196-20-Standard Test Methods for Rheological Properties of Non-Newtonian Materials by Rotational Viscometer

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

Features

1. Engler viscometer for measuring the viscosity of liquid petroleum products.

2. Standard design following the Engler method for kinematic viscosity determination.

3. Temperature-controlled bath maintains the required test temperature.

4. Clear graduated receiver and timer for reproducible viscosity measurements.

5. Suitable for lubricating oils, fuel oils and other petroleum derivatives.

FAQ

Q1: What is the Engler viscometer mainly used for?

A: It is used in petroleum testing laboratories to measure the viscosity of lubricating oils, fuel oils and related products using the Engler method. Viscosity data supports product quality control, blending and specification compliance in the petroleum industry.

Q2: What standards does the viscometer comply with?

A: The instrument follows the Engler viscosity test method and relevant GB/T and ISO standards for petroleum product testing. Test procedures should follow the applicable standard method. Compliance documentation can be provided on request.

Q3: What is the warranty period for the viscometer and key components?

A: The complete unit carries a 12-month warranty covering the bath, controller and instrument body. Glassware, thermometers and accessories are excluded. Damage from improper handling or unauthorised repair is not covered.

Q4: Is the viscometer difficult to operate?

A: Operation requires basic training in viscosity testing procedures and temperature control. The manual explains sample loading, timing and calculation, and remote guidance is available. Careful cleaning between samples is important for accuracy.

Q5: What is the typical lead time for order delivery?

A: 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.

Q6: Does the viscometer require calibration or verification?

A: The instrument and bath thermometer should be verified periodically against calibrated references, typically every 6 to 12 months. The unit is factory tested before delivery. Optional calibration service can be arranged.

Q7: Are consumables or spare parts universal?

A: Glass receivers, thermometers and standard spare parts are available through our channel. No proprietary consumables are required. Provide the model and serial number when ordering.

Q8: Can the viscometer be customised?

A: Yes, options include different temperature ranges, digital timing, 220V or 110V supply and data recording. We confirm each option before order confirmation.

Q9: Is installation and commissioning included?

A: The unit is commissioned by following the manual, including bath filling, electrical checks and a test run. Remote guidance is available during commissioning. On-site installation can be arranged separately.

Q10: What samples should not be tested in this viscometer?

A: Corrosive or highly volatile samples may damage glassware or affect safety. Samples must be compatible with the test temperature and clean before measurement. Follow laboratory safety regulations.
