HLC-3020SM High And Low Temperature Thermostat, -30 To 150 C (CAT#: STEM-AL-0466-ZJF)

The HLC-3020SM is a vertical high and low temperature thermostat with LED display and membrane keypad control. It provides a uniform hot and cold liquid field for laboratory testing and production workflows. The 20 L tank supports medium-volume constant-temperature applications. Internal and external circulation support direct bath use and connected equipment temperature control. A pressure and suction pump circulates bath liquid to improve uniformity. The system can be used as a direct heating or refrigeration source. Liquid-contact materials include stainless steel and high-performance plastics. Low level and high-temperature protection support routine safety.
