WRS-1B Digital Melting Point Apparatus WRS-2A Digital Melting Point Apparatus
WRS-2 Micro-computer Melting Point Apparatus
Intended use:
The apparatus is used for measuring the melting point of crystalline substan, so as to determine the purity of the substan. It is mainly used for measuring the melting point of crystalline compounds, like drug, dye, and flavor, etc. With photoelectric test, digital keyboard input, and large-screen backlit LCD display, the apparatus may show the melting curve directly. There is a RS232J interfa. WRS-2A may measure three samples at the same time, and may calculate the average value of initial and final melting points automatically.
Characteristics:
◆ Range for the melting point measurement: at room temperature :about 300℃
◆ Minimum indication for temperature display: 0.1℃
◆ Rate of linear temperature increase : 0.2℃/min, 0.5℃/min, 1℃/min, 1.5℃/min,
2℃/min, 3℃/min, 4℃/min, 5℃/min, with 8 channels
◆ Accuracy rate for the measurement: <200℃; ±0.5℃; ≥200℃; ±0.8℃
◆ Weight of the apparatus: 11kg
◆ Dimensions of the apparatus: 398 * 280 * 170 (mm)
