Electric constant temperature water temperature box / Electric heating constant temperature three-purpose water tank

Scope of application
It is suitable for distillation, drying, concentrated and constant temperature heating of chemical drugs and biological products, serum inspection and biochemical experiments, constant temperature cultivation, and boiling and disinfecting syringes and small surgical instruments.

Structural features
The shell is made of high-quality cold-rolled steel plate, with plastic spraying on the surface. The studio, lower frame and upper frame and cover top are made of stainless steel plates. The box and the studio are filled with high-quality insulation materials. The structure design is reasonable, the corrosion resistance is strong, and the shape is beautiful. The temperature control system adopts a more reliable adjustment and control device, which has strong heat sensitivity and high sensitivity. It can be adjusted at will within the range of use, and can directly measure the actual water temperature in the box. The heating device adopts a closed heater, which can be directly immersed in water, and has a small heat loss. The microcomputer intelligent thermostat displays the set temperature and the actual temperature.
