ASTM D1401 Automatic Water Separability Of Petroleum Oils And Synthetic Fluids

KN-1401Z Automatic Water Separability Tester

Overview

  KN-1401Z Automatic Water Separability Tester conforms to ASTM D1401 Standard Test Method for Water Separability of Petroleum Oils and Synthetic Fluids. This apparatus provides a guide for determining the water separation characteristics of oils subject to water contamination and turbulence. It is used for specification of new oils and monitoring of in-service oils. And it covers measurement of the ability of petroleum oils or synthetic fluids to separate from water. Although developed specifically for steam-turbine oils having viscosities of 28.8–90 mm2/s at 40°C, this test method may be used to test oils of other types having various viscosities and synthetic fluids at other test temperatures. It is recommended, however, that the test temperature be raised to 82 ± 1°C when testing products more viscous than 90 mm2/s at 40°C.

Features

1. 7-inch HD color touchscreen for clear interface display and user-friendly operation.

2. Equipped with four sets of stirring paddles and four automatic lifting mechanisms, enabling simultaneous processing of four samples. This parallel sample handling capability significantly enhances test efficiency, making one instrument equivalent to using four separate instruments.

3. Utilizes PID temperature control technology with high precision down to ± 0.1℃

4. Automatic lifting of stirring assemblies; linear-guide rail mechanical transmission ensures noise-free, stable, and reliable operation.

5. Imported PT100 temperature sensors for high-precision temperature measurement.

6. Allows setting of parameters such as temperature setpoints and fine-tuning values, which can be saved upon completion.

7. High-torque stirrers use high-power motors and self-locking chucks, capable of stirring viscosities up to 100,000 mPa·s

8. Four independent LCD digital-control stirrers with stepless speed adjustment ranging from 100 to 2000 rpm.

9. Square stainless steel liquid bath with illuminated glass observation window, ensuring compact size, lightweight design, and refined aesthetics.
