The cryostat is controlled by a single microprocessor

Shanghai Xinzhuang Instrument microcomputer temperature control low temperature thermostat adopts single-chip microprocessor control, self-tuning PID adjustment, imported platinum resistance (Pt100) temperature measurement, high temperature control precision, small fluctuation; high quality Italian technology compressor (low It adopts fully imported compressor unit at -40 °C or 30 liter series), with high cooling efficiency and low noise. The instrument works stably and reliably, and the operation is convenient and safe. The product has the following advantages: 1. It adopts microcomputer temperature control PID adjustment and self-tuning control technology, high temperature control precision; 2. It has breakage protection function; 3. Lower limit over temperature alarm function; 4. Fully enclosed brand compressor, cooling 5, left and right sides have folding handles, easy to move; 6, lifting temperature is fast, stable and reliable; 7, set temperature and measuring temperature are displayed by two digital windows; 8, circulating pump can be used for constant temperature liquid Leading cycle; DC series cryostat is widely used in bioengineering, medicine, food, chemical, metallurgy, chemical analysis, petroleum and other fields to provide users with a high-precision, controlled, uniform temperature field source. The ideal thermostatic bath for institutions, universities, factory laboratories, and quality inspection departments.

Installation and operation: 1. Remove the packaging, clean it, and put it on a firm workbench. 2. If it is a 20-liter, 30-liter series and a -65 °C, -80 °C thermostat, the two sides of the stencil should be removed first, then the two packaging screws are removed, the thermostat is lifted off the wooden frame and placed Firm on the workbench. 3. The newly arrived thermostat must be parked for 12 hours after being unpacked and then powered on. 4. Add liquid medium (anhydrous alcohol or ethylene glycol) to the tank so that the liquid level of the medium is lower than the working plate by about 30mm. 5. Connect the circulation pump to the inlet and outlet. 1 When the circulation pump does not need to be externally cycled, simply connect the “inlet” and “outlet” with a hose. 2 When the circulating pump is used for constant temperature liquid circulation, apply two hoses, respectively connect the “outlet” tube to the inlet of the experimental container outside the tank, and connect the “inlet” tube to the outlet tube of the experimental container outside the tank. 6. Turn on the power, turn on the “power” switch, and turn on the “cycle” switch.

Environmental requirements 1. The thermostatic bath should be placed on a sturdy workbench; 2. No vibration and no harmful gases; 3. The room temperature should be relatively stable, not high or low, affecting the temperature control accuracy; room temperature should be around 25 °C, Do not exceed 30 ° C (especially -40 ° C, -65 ° C, -80 ° C thermostatic bath), too high room temperature will affect the heat dissipation of the compressor, reduce cooling efficiency, and easily cause failure; 4, after working for a period of time If the cooling rate is slowed down, the plastic mesh plate of the thermostatic bath should be removed to remove dust from the compressor and heat sink.
