Product Introduction:

The microcomputer controlled low-temperature constant temperature bath adopts single-chip microprocessor control, self-tuning PID regulation, high-precision platinum resistance (Pt100) temperature measurement, high temperature control accuracy, and small fluctuation; Compressors using high-quality fully enclosed technology (below -40 ℃ or 30 liter series using fully dual compressor cascade refrigeration technology and heat exchange system) have high refrigeration efficiency and low noise. The instrument works stably and reliably, with convenient and safe operation.

user-friendly designThe foldable handles on both sides facilitate the transportation of instruments. The 20L and above series and low-temperature constant temperature baths below -40 ℃ use heavy-duty self-locking casters for easy movement. The low-temperature constant temperature bath adopts integral foaming technology, which has good insulation performance and effectively reduces the loss of cooling capacity.

Professional circulating mixing design:This ensures that the liquid in the tank is evenly and smoothly dispersed in the internal circulation, and the heat exchange is smooth. The flow rate of the low-temperature constant temperature bath stirring pump with a volume of over 20L is 10L/min, and the remaining 8L/min. The temperature fluctuation is ± 0.05 ℃, and the display resolution is 0.1 ℃.

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.

Environmental requirements for constant temperature bath:

1. The constant temperature bath should be placed on a sturdy workbench;
2. No vibration, no harmful gases;
3. The room temperature should be relatively stable and not fluctuate rapidly, otherwise it will affect the temperature control accuracy; The room temperature should be around 25 ℃, especially for constant temperature baths at -40 ℃, -65 ℃, and -80 ℃. Excessive room temperature can affect compressor heat dissipation, reduce refrigeration efficiency, and easily cause malfunctions;
4. The constant temperature bath should be regularly maintained, especially if the cooling rate slows down after working for a period of time. The plastic mesh plate of the constant temperature bath should be removed to remove dust from the compressor and heat dissipation plate.

New optional constant temperature bath with internal/external temperature control function description

This oneThe sink has internal and external circulation functions (optional with an external extended PT100 temperature sensor), which can conduct constant temperature experiments inside the sink and also establish a closed second temperature field externally. When used as a second temperature field, the temperature of the second temperature field can be accurately measured and controlled through internal and external temperature sensors on the back of the machine.

usage method:

When only conducting a constant temperature test in the sink, turn the temperature switch to the internal temperature.

When it is necessary to establish a second temperature field for use, connect the external temperature sensor equipped on this machine to the machine, first turn the temperature switch to the internal temperature, set the temperature of the water tank to the desired temperature, wait for the instrument to display a stable temperature for 10-20 minutes, then turn the temperature reduction switch to the external temperature. At this time, the constant temperature bath can accurately control the temperature of the second temperature field through the internal PID temperature control instrument.

Attention: Do not directly turn the temperature setting switch to the external temperature, in order to avoid accidents caused by the slow rise of the external temperature and the high temperature inside the constant temperature bath.
