*Accurate measurement of LPG non‑volatile residues per SY/T 7509*
Liquefied Petroleum Gas (LPG) may leave residues after evaporation, which can affect combustion efficiency, clog valves, and damage downstream equipment. The LPG Residue Tester is designed and manufactured in strict accordance with the SY/T 7509 test method. It is specifically used to determine the residue content of liquefied petroleum gas after volatilization at 37.8 °C – a critical quality parameter for LPG producers, inspectors, and end‑users.
| Parameter | Value |
|---|---|
| Power supply | AC220V ±10%, 50Hz |
| Input power | 2 kW |
| Temperature control range | +50 °C ~ –60 °C |
| Temperature control accuracy | ±0.1 °C |
The tester integrates four functional modules:
Cold bath – for low‑temperature residue separation
Water bath – for precise temperature control during the test
Test tube rack – holds sample tubes securely
Stirring device – ensures uniform temperature distribution
Key Features & Advantages✔ Precise temperature control from +50 °C down to –60 °C
With an accuracy of ±0.1 °C, the instrument provides stable, repeatable conditions required by the SY/T 7509 method. The wide range allows both residue evaporation and cooling steps to be performed.
✔ High‑performance refrigeration system
The cold bath utilizes imported compressors and cascade refrigeration technology, delivering fast cooling, stable operation, and extended service life – ideal for labs running frequent LPG residue tests.
✔ Digital temperature controller – intuitive and easy to use
The water bath is controlled by a digital temperature controller with a clear display, allowing operators to set and read temperatures effortlessly.
✔ Compact, robust, and aesthetically designed
The unit features a compact structure, attractive appearance, and user‑friendly layout, saving bench space while ensuring ease of operation.
✔ Designed for SY/T 7509 compliance
Fully compliant with the industry standard for LPG residue determination, ensuring your test results are consistent, reliable, and widely accepted.
