MPA160SRS MPA160& MPA161 Digital Melting Point Apparatus for StudentsDigiMelt is a modern, low cost, digital melting point apparatus designed specifically for the student lab. Students learn the visual detection capillary method of melting point determination without the frustration of trying to control the oven temperature. DigiMelt rapidly heats the oven to the programmed start temperature, then ramps at the specified rate. The student carefully observes the samples and records the melting points with a touch of a button.Digital Temperature ReadoutDigiMelt incorporates a platinum resistance temperature detector (RTD) instead of the usual mercury thermometer. This means better accuracy on the readings, and no more mercury cleanup from broken thermometers. The RTD is encased inside the oven block making it virtually unbreakable.Microprocessor Temperature ControlSome student instruments use a large knob that simply throttles power to the oven without any sense of what the target temperature is. DigiMelt uses an RTD for feedback, so it "knows" the oven temperature. This means the students can enter a start temperature, a ramp rate, and a stop temperature and the microprocessor takes care of the rest. Furthermore, the microprocessor can deliver variable amounts of power to the oven, so it can quickly ramp to the starting temperature, then perform the ramp as slowly as 0.5 oC/min.High Quality OpticsRather than forcing the student to peer through a tiny lens with poor illumination, the DigiMelt uses a large magnifier that allows plenty of eye relief. The user can see all three capillaries easily at a comfortable distance from the instrument. White LEDs are used to provide high-contrast illumination.Tube TapperFor many students, the melting point lab is the first time they have touched a capillary. This can lead to lots of capillaries on the floor and many broken capillaries. DigiMelt employs an integral cell phone vibrator motor to let students pack their sample without tapping them on the bench or dropping them through a long glass tube. A molded guide in the chassis allows students to pack three samples at a time.Easy MaintenanceCleaning the lens is as simple as removing the lens retaining ring. If a student should break a capillary, the entire lens holder assembly slides out for easy clean up of the broken glass. Replacing thermometers is a thing of the past as the RTD will never break and cannot be removed from the instrument. Unlike conventional incandescent bulbs that must be periodically replaced in some student instruments, the white LEDs used in DigiMelt will last a lifetime.Safer for StudentsThe DigiMelt uses an internal RTD thermometer, which means students and TAs are never exposed to toxic mercury vapors. Some student instruments will reach 500 °C and stay at that temperature indefiniy - a severe burn hazard. The DigiMelt’s maximum temperature is 260 °C, which allows testing of virtually all organic compounds a student might examine. Inligently designed cowling protects students from touching the hot oven. Furthermore, the oven will automatically turn off after being idle for 30 minutes.8163a,8164a,81618a,81619a,81624b,81623a,81623b,81625a,81521b,81533b,81525a,8156a,81576a,81570a,81578a, n7744a,,86100A,86100C,86105A,86103A,83493A,83492A,83494A,81610A,81632B,81636BN5980A,86130A,86120B,86120C,86107A,86105C,86116CKEITHLEY ,2400,2420,6517b,2602a, 2612TEK DSA8200 80E04 80C08-CR4,80C02Anritsu 9710BYOKOGAWA 2201,2200-42186100C 安捷伦 Agilent 86100C 宽带示波器主机Tektronix DSA820086105C 安捷伦 Agilent 86105C 9 GHz光采样模块安捷伦 Agilent N9020A 信号分析仪R&S CMW500 无线通信综合测试仪keithley2400型通用性源表Keysight 是德3458A 数字多用表8156A 安捷伦 Agilent 8156A 光学衰减器81576A 安捷伦 Agilent 81576A 可变光衰减器模块81570A 安捷伦Agilent 81570A 可变光衰减器模块86100A 安捷伦 Agilent 86100A宽带示波器86105A 安捷伦 Agilent 86105A 模块86105D 安捷伦Agilent 86105D 模块Agilent 81578A-0628164A 安捷伦 Agilent 8164A 光波测量系统Keysight 是德N7744A 多端口光功率计Agilent 8349
