High Precision Low Temperature Constant Temperature Water Tank, 30L, -20~100℃, SHANGHAI HENGPING INSTRUMENT (CAT#: STEM-GLE-0913-YJL)

High Precision Low Temperature Constant Temperature Water Tank, 30L, -20~100℃, model DC-2030A is manufactured by Shanghai HengPing Instrument and meter Co.,Ltd. DC-A/B series high-precision low temperature thermostatic bath adopts single-chip microprocessor temperature control, self-tuning PID adjustment, adopts PT100 platinum resistance temperature measurement, and the temperature control accuracy can reach 0.01 degrees. The fluctuation is small, and some models use high-quality compressor units, which have high cooling efficiency and low noise. Provide users with a high-precision, controlled and uniform temperature constant temperature field source, the instrument is stable and reliable, and the operation is safe and convenient.
DC-A/B series high-precision low-temperature constant temperature bath adopts single-chip micro-processing control, self-tuning PID adjustment, high-precision platinum resistance (Pt100) temperature measurement, high temperature control accuracy and small fluctuation. It adopts high-quality fully enclosed technology compressor (lower than -40℃ or 30L series adopts full double compressor cascade refrigeration technology and heat exchange system), which has high refrigeration efficiency and low noise. The instrument works stably and reliably, and the operation is convenient and safe.
Humanized design: The foldable handles on both sides are convenient for carrying the instrument, and the 20L and above series and the low temperature thermostat below -40℃ adopt heavy-duty self-locking casters, which are easy to move. The Low Temperature Constant temperature tank adopts the overall foaming process, which has good thermal insulation performance and effectively reduces the loss of cooling capacity.
Professional circulation stirring design: ensure that the liquid in the tank is evenly dispersed and smooth in the internal circulation, and the heat exchange is stable. The flow rate of the stirring pump in the Low Temperature Constant temperature tank with a volume of more than 20L is 10L/min, the remaining 8L/min, the temperature fluctuation degree is ±0.02°C, and the display resolution is 0.01°C.
Suitable for internal/external temperature control applications: the sample can be directly placed in an open bath for constant temperature, or an external measurement unit that requires constant temperature can be controlled externally.
