Working principle of thermostatic water bath.

The thermostatic water bath provides a liquid environment with cold and heat controlled and uniform temperature for users.

Working principle of thermostatic water bath.

1. Temperature control principle of constant temperature water tank


When the thermostatic water bath in the low-temperature constant temperature bath is lower than the set value, the electronic relay will drive the heater to work, and when the temperature reaches the set temperature, the heating will be automatically stopped. The high-power circulating pump and agitator device inside the equipment will make the heat evenly distributed and make the temperature measurement more accurate.


2. How to improve the sensitivity during use?


(1) The better the fluidity and heat capacity of the medium used in the experiment, the higher the temperature measurement sensitivity

(2) The smaller the heat capacity of the thermometer and the larger the contact surface with the constant temperature medium, the smaller the adhesion between mercury and platinum wire and capillary wall, and the higher the sensitivity

(3) The smaller the heater power, the higher the sensitivity

(4) The higher the power of the stirrer and the greater the stirring speed, the more uniform the temperature of each part of the constant temperature medium and the more accurate the temperature display

(5) The larger the flow of the circulating pump of the low-temperature constant temperature reaction bath, the more uniform the temperature of the constant temperature medium

(6) The heater is placed near the stirrer, which can quickly transfer heat to all parts
