Digital magnetic stirring water bath (double row)

1、 Purpose:

HH-4JDigital magnetic stirring water bath(double row)Using stainless steel plates and precision machining manufacturing processes, it has the characteristics of high temperature resistance and corrosion resistance. The temperature control device adopts high stability operational amplifier and double integration high-precisionA/DDesigned with conversion technology and far-infrared heating technology. The product has a short thermal equilibrium time, small temperature fluctuations, and good uniformity,LEDDisplay accurately and intuitively. This water bath pot comes with4Magnetic stirring can evenly stir the liquid in the water bath or the liquid in the container! It is a water bath specially designed for laboratory research.

IIIHH-4JDigital magnetic stirring water bath(double row)Installation and use:

1Before installing the equipment, the water bath should be placed on a flat workbench for visual inspection. The appearance should be intact, the instrument appearance should be intact, the wire insulation should be good, the plug should be intact, the power switch should be flexible, and the user must use a single-phase three pole power socket. The grounding electrode of the power socket should have a reliable ground wire.

2Before powering on, inject clean water into the sink of the water bath (if possible, use distilled water to reduce scale). After adding clean water to the water bath, there should be no water leakage, and the liquid level should be kept at a distance from the upper opening2—4cmThe distance should be set to prevent water from overflowing into the electrical box and damaging the components.

3Setting and use of digital temperature control instruments:

Turn on the power switch, the temperature controller lights up, Click on the function key, at this pointzuiThe last digit starts flashing. Click △ or ▽ to select the working temperature, then click the function key again to exit. At this point, the system will run according to the set parameters.

4To stir the liquid in the beaker, simply place the magnetic stirrer into the beaker! Then adjust the speed knob to adjust the speed,4The group can be adjusted separately!

After the experimental work is completed, turn off the power switch, cut off the power supply of the equipment, and drain the water in the sink completely.
