Brief introduction DT-ZRD-1 automatic melting point apparatus using photoelectric detection, digital temperature display technology, with initial melting. Final melting, automatic display function, the use of large screen liquid crystal display can directly display up to three melting curve, temperature system applied linear correction of platinum resistance as detection element, make the process more efficient, accurate, integrated circuit implementation fast onset temperature "set, eight stalls linear heating rate free choice. The instrument automatically shows the initial temperature, the final melting, and automatic recording of melting curve, automatically calculate the average value of the data, the entire process of unattended, automatic completion of all detection. The instrument uses the capillary tube as the sample tube. Technical parameter 1. Analysis ample quantity at the same time: 1 2 Melting point measurement range: room temperature to 320 DEG C 3. The rate of initial temperature: room temperature to 320 DEG C is not greater than 320 DEG 6min at room temperature is not greater than 7min 4Temperature display the minimum reading: 0.1 degrees 5 Linear heating rate: 0.2 degrees /min, 0.5 degrees /min, 1 degrees /min, 1.5 degrees /min, 2 degrees /min, 3 degrees /min, 4 degrees /min, 5 degrees /min eight 6 Temperature accuracy: + 0.4 C (<200 C) + 0.7 C (<300 C) 7 Repeatability: heating rate is 0.2 DEG /min and 0.2 DEG C 8 Standard size: 1.4mm diameter capillary inner diameter is 1.0mm 9 Power supply: 220V 22V + AC, 50HZ 10 Power: 100W 11 dimensions (length, width, height): 200mm * 312mm * 455mm 12 weight: 10Kg
