II. Performance Features

The ZT-S08Z model fully automatic high-temperature high-shear tester is designed and manufactured according to the standard SH/T0703. It specifies a temperature of 150±0.1°C and an apparent shear rate of 1.4×10...⁶s^-1Under the given conditions, the high-temperature, high-shear (HTHS) apparent viscosity of the engine oil measured by a multi-capillary viscometer equipped with pressure, temperature, and timing devices.

1. Instrument Composition:

High-temperature, high-shear viscosity and apparent viscosity measuring instrument is mainly composed of the measuring unit, metal isothermal bath, and electrical control system.

Measurement Unit: Comprises capillaries, spherical pressure valves, copper tubes, and stainless steel tubes, among others.

Metal Constant-Temperature Bath: Includes metal bath, heating system, and temperature sensor.

Electrical Control System: Includes systems for temperature control, pressure control, pressure display, and timing tests.

At 150±0.1°C, with an apparent shear rate of 1.4×10⁶s^-1Under specified conditions, the system automatically adjusts the set pressure value, maintains stable pressure, releases pressure automatically, times automatically, and converts test requirements to approximate pressure values. The entire operating system is stable in performance and easy to operate.

2. Instrument Accuracy:

(1) Temperature Measurement Function: Utilizes imported thermosensitive elements, offering high precision on the instrument display, ensuring more accurate temperature control, and minimizing experimental errors.

(2) Correction Feature: Bath temperature can be adjusted.

(3) Inspection Methods: Dual detection with pressure and sound control to ensure reliable data.

(4) Circuit Control: Utilizes industrial PLC control system, with a simple peripheral circuit, stable and reliable operation, modular design for consistent performance, and low failure rate.

3. Instrument Automation:

The instrument features a 7-inch color LCD touch screen, full Chinese menu, and easy operation.

(2) Utilizes a metal bath for quick and efficient heating.

(3) Real-time tracking of bath temperature changes with high test accuracy.

(4) Full-process automatic detection, judgment, storage, and printing.

(5) The instrument can cyclically store 10,000 test results.

(6) Utilizes a thermal printer, featuring fast printing speed and noiseless operation.

4. Instrument Safety:

(1) The instrument uses a metal bath, ensuring no pollution, offering both safety and energy conservation.

(2) The instrument features a well-designed thermal insulation system, which saves energy and prevents operators from being scalded.

(3) The instrument is equipped with an overheating protection device, which automatically shuts off the heating system for instruments that exceed temperature limits, enhancing the instrument's safety.
