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 substance, so as to determine the purity of the
substance. 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 interface. 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) |
