The drk8023 melting point meter uses PID (automatic temperature control) technology to control the temperature. It is a domestic leading and internationally advanced product of our company. The biggest feature of the instrument is the dual use of visual measurement and automatic measurement, that is, the combination of visual observation measurement and photoelectric detection automatic measurement in one instrument. In this way, both the photoelectric detection automatic measurement function is convenient for users to use; and the melting point of the substance can be measured visually to meet the needs of the melting point measurement of dark-colored samples. Therefore, the instrument measures a wide range of samples and is very convenient to use. The instrument can measure three samples at the same time, display and key in a large touch screen, and has an RS232 serial port and a USB interface. Melting point measurement range: room temperature to 320°C The minimum value of temperature digital display: 0.1℃ Linear heating rate: 0.2°C/min, 1°C/min, 1.5°C/min, 3°C/min, Standard capillary size: outer diameter Φ1.2mm inner diameter Φ1.0mm height 120mm Sample filling height: ≥3mm Power supply: AC220V±22V, 100W, 50Hz Indication error: when the ambient temperature is 23℃±5℃, the following requirements should be met: a) Within the range of less than 200 ℃: ±0.5 ℃ b) Within the range of 200 ℃ -320 ℃: ±0.8 ℃ Repeatability of indication: when the heating rate is 1.0℃/min, the uncertainty of the sample is 0.3℃ Linear heating rate error: not more than 10% of the nominal value Instrument size: 390mm×320mm×240mm Net weight of the instrument: 12kg
