TP655 Petroleum Density Tester with Touch Screen and Temperature
Control
Product Overview
TP655 Petroleum Density Tester is a professional laboratory
instrument designed for measuring the density of crude oil,
petroleum products, and petroleum/non-petroleum mixtures with Reid
vapor pressure not exceeding 180 kPa. The instrument can accurately
measure the density of transparent, low-viscosity liquids and is
also suitable for viscous liquids. It is widely used in petroleum,
chemical, and electric power industries, research institutes, and
laboratory testing departments.
Based on GB/T 1884-2000 standard testing conditions, the instrument
uses a constant-temperature water bath system to maintain the
sample at the required temperature, ensuring accurate density
measurement results.
Product Description
The TP655 Petroleum Density Tester is designed for laboratory
determination of petroleum product density using a hydrometer
method under controlled temperature conditions. During operation,
the sample is placed into a density measuring cylinder and heated
in a water bath to the specified temperature. After thermal
equilibrium is reached, the petroleum density meter is inserted
into the sample. The density value is obtained by reading the
hydrometer scale together with the sample temperature.
The instrument adopts microcomputer control technology, integrated
temperature control, automatic stirring system, and illumination
design, providing stable temperature conditions, convenient
operation, and reliable test results.
Key Features
- 5 Inch Touch Screen Operation: Equipped with a 5-inch color touch LCD display with Chinese
human-machine interface for easy operation and parameter setting
- Precise Temperature Control: PI temperature control technology with high temperature accuracy,
short heating time, and temperature control accuracy of ±0.1℃
- Automatic Stirring System: Built-in microcomputer control system with automatic stirring
paddle operation to ensure uniform sample temperature
- Clear Sample Observation: Built-in LED lighting system providing soft and stable
illumination for improved sample visibility during testing
- Wide Temperature Range: Temperature range from 0-100℃, suitable for density measurement
below or above ambient temperature with optional cooling device
available for testing below 20℃
- Safe and User-Friendly Design: Reasonable structure design with simple operation and reliable
laboratory performance
Working Principle
The TP655 Petroleum Density Tester works according to the
hydrometer measurement method specified in GB/T 1884-2000. The
petroleum sample is placed into the density cylinder and heated in
a controlled water bath until reaching the required test
temperature (normally 20℃ under atmospheric pressure of 101.325
kPa). After the sample temperature becomes stable, a suitable
petroleum hydrometer is placed into the sample. When the hydrometer
floats freely and reaches equilibrium, the density value is
obtained by reading the hydrometer scale and recording the sample
temperature.
Applications
TP655 Petroleum Density Tester is widely applied in:
- Petroleum Industry: Crude oil density testing, petroleum product quality inspection,
fuel oil laboratory analysis
- Chemical Industry: Chemical liquid density measurement, raw material inspection
- Power Industry: Oil quality analysis, transformer oil related testing applications
- Research Institutions: Laboratory research, scientific experiments, quality control
