constant temperature water bathIt is a laboratory equipment that maintains a constant water bath temperature through a heating and temperature control system, and has the following key components:
heating system
Heating tube: Made of stainless steel or nickel chromium alloy material, it heats the water bath through resistance heating.
Power matching: Select the power according to the water bath capacity (such as a 5L water bath with a power of about 500W) to ensure heating speed and temperature uniformity.
temperature control system
Sensors: PT100 platinum resistors or NTC thermistors are usually used to monitor water temperature in real time.
Controller: PID intelligent temperature control algorithm achieves precise temperature control (error ± 0.1 ℃) by adjusting the heating power.
Display mode: The digital LCD screen displays the set temperature and actual temperature, and some models support temperature curve recording.
mixing system
Magnetic stirring: The built-in magnetic pump drives the stirring element to rotate, promoting uniform temperature of the water bath (with adjustable stirring speed).
Circulating pump: The high-end model is equipped with an external circulating pump, which can be connected to an external container to achieve constant temperature expansion.
safety protection
Overtemperature alarm: When the temperature exceeds the set value, the heating will be automatically cut off and an alarm will be triggered.
Leakage protection: Built in leakage switch to prevent the risk of electric shock.
Low water level protection: Automatically stops heating when the water level is too low to avoid dry burning and damaging the equipment.
