• Standard high-precision external PT1000 temperature probe immerses directly into reaction liquid to eliminate plate-solution temperature offset, capturing real internal sample liquid temperature to comply with traceable precision data standards for test reports and academic papers.
• Extended timer function from 1min to 99h59min enables timed automatic shutdown for unattended overnight & split-time workflows, eliminating manual supervision for long-duration constant-temperature reflux and batch digestion experiments.
• Flashing "HOT" residual heat warning at 50℃ after power off: if plate temperature exceeds 50℃ while power cable remains connected post shutdown, LCD continuously flashes "HOT" to alert operators against high-temperature scald injury.
• Built-in industrial RS232 data port connects to PC supporting software for remote setting of speed, temperature and timer duration, automatic full-process logging & export of complete experimental parameters (temperature, speed, time) for file archiving and traceability.
• Dual independent high-resolution LCD screens separately display real-time stirring speed and heating temperature for intuitive, clear monitoring of reaction status.
• Multi-layer integrated safety protection suite: global 420℃ overheat trigger automatically cuts all heating output, IP21 dust-proof housing and spark-free explosion-proof motor eliminate risks of dry heating, fire and vessel rupture for safe stable long-duration continuous operation.
• Wide range of optional supporting accessories including support stands, clamps, temperature probes and reflux assemblies enable fast assembly of complete constant-temperature reflux & distillation reaction systems for one-stop full synthesis setup demands.
