Product Overview

The A1290 Ash Content Tester is a laboratory testing instrument designed to determine the ash content of petroleum products.

Ash content is an important quality parameter for petroleum products because inorganic residues and non-combustible materials can affect product quality, equipment cleanliness and subsequent processing performance. The A1290 provides a controlled high-temperature environment for the determination of ash in petroleum samples.

The instrument is widely used in petrochemical laboratories, petroleum testing laboratories, coal laboratories, building material laboratories, metallurgical laboratories, scientific research institutions and university laboratories.

The A1290 adopts a three-sided heating furnace structure, with heating elements located on both sides and the top of the furnace chamber. This design helps improve temperature distribution and provide a stable heating environment for ash determination.

The furnace chamber uses high-quality vacuum fiber insulation material, which provides good thermal insulation, fast heating and improved energy efficiency.

Main Features

1. Three-Sided Heating Design

The furnace chamber is heated from both sides and the top, creating a three-sided heating structure.

This configuration helps improve heat distribution inside the furnace and provides a more uniform temperature environment for laboratory testing.

2. Stable Double-Layer Furnace Housing

The A1290 uses a double-layer furnace housing structure, which improves structural stability and helps reduce heat transfer to the external housing.

3. Durable Steel Housing

The outer cabinet is manufactured from high-quality steel plate using stamping and welding processes.

The robust construction is designed for long-term laboratory use.

4. Vacuum Fiber Furnace Chamber

The furnace chamber uses high-quality vacuum fiber insulation material.

Its low thermal mass helps the instrument achieve:

• Fast temperature rise
• Good heat insulation
• Lower heat loss
• Improved energy efficiency
• Stable high-temperature operation

5. High-Temperature Testing Capability

The instrument provides a temperature range from ambient temperature to 1000°C, while the specified temperature control condition is 775±25°C.

This makes the A1290 suitable for high-temperature ash determination applications

A1290 Ash Determination Working Principle

The basic principle of petroleum product ash determination is to heat a prepared petroleum sample under specified conditions until combustible components are removed.

The remaining inorganic residue is then treated as the ash content of the sample.

The general testing process includes:

Sample Preparation → High-Temperature Heating → Combustion → Residue Formation → Cooling → Weighing → Ash Content Calculation

The exact sample preparation, heating procedure and calculation method should follow the applicable testing standard, such as GB/T 508, GB/T 2433 or SH/T 0067.
