Introduction: HR-2 gray melt tester gray cone observation mode is CCD high-definition industrial camera, large screen 10 inch 4:3 digital LCD monitor display graphics, integrated structure, the left side to send samples, convenient and fast, single-chip automatic control Heating rate, the heating process of ash melting point determination is automatically completed according to the national standard, and the control parameters can be selected and modified within a certain range. Another optional heating program is used for other heating and thermostatic processes, which is the determination of coal ash fusion in the laboratory. Intelligent laboratory instrument. Technical Parameters: 1. Control mode: With the single chip as the core, the temperature and current are automatically corrected, and the automatic phase shift triggers the thyristor closed-loop control heating current. The heating process of ash melting point determination is automatically completed according to the national standard, and various fault prompting functions are performed; 2, Temperature range: 0-1600 °C, resolution 1 °C, with S-value thermocouple. 3, time range: 0-999 minutes, resolution 1 minute (1 second less than 10 minutes). 4, heating rate: 900 °C before, 15-20 °C / min. After 900 °C, 5 ± 1 °C / min. 5, temperature measurement error: ± 3 °C 6, timing error: less than 1 second / hour 7, the power supply voltage: 220V ± 10% 50Hz 8, control current: up to 30 amps 9, instrument power consumption: 4KW 10, the use of the environment: temperature 0 - 40 °C, relative humidity is not more than 80%. 11, working mode: continuous. 12, the alarm prompt: every 900 minutes after 900 °C alarm once, to remind the laboratory technician to observe the gray cone shape recording temperature. 13. Dimensions: 860mm × 380mm × 470mm
