1、 Overview
The YG252D melting point meter is controlled by a microcomputer and is used to test the melting point of objects such as powder, polyester chips, and synthetic fibers (except for dark opaque objects). The instrument automatically determines the melting point by analyzing the changes in light transmission during heating, or can manually determine the melting point through visual inspection with a microscope (magnifying glass).
2、 Main technical parameters
1. Usage conditions
1.1 Environmental temperature of 15-30 ℃, relative humidity not exceeding 80%
1.2 Avoid direct sunlight on the photosensitive device

1.4 Power supply AC220 ± 10V
2. Main technical indicators
2.1 Melting point test range is 50-320 ℃, with an error of ≤± 0.5 ℃. This instrument provides standard powder (sulfamethoxazole) with a melting point of 198.5 ℃± 0.5 ℃
2.2 Heating rate 2, 3, 4, 5 degrees per minute (optional)
2.3 Melting mode (manual and automatic)
Automatic fusion reporting (only reporting full fusion)
Manual melting (microscopic visual inspection with button melting)
2.4 The printer can print each test data and automatically print the arithmetic mean
2.5 Rated power: 140W
