The temperature fluctuation is less than 0.005 ℃, and the temperature range covers -100-400 ℃. Existing refrigeration or heating technologies can accelerate production processes, such as Lauda replacing non economical cooling processes with tap water using environmentally friendly equipment, effectively utilizing raw energy through various measures, and measuring interface and surface tension as well as viscosity of liquid samples. The equipment shell is coated with white anti-corrosion coating, and the control keyboard is a seamless waterproof keyboard. The seamlessly embedded waterproof control panel and power switch allow the operator to turn on and off the machine and set it with wet hands, and prevent accidental liquid splashing from damaging the circuit. The work and temperature sensors are located atUniversal water bathAt different heights inside, when the temperature sensed by two sensors differs by more than 15 ℃, the instrument considers that the liquid level in the bath is too low and there is a possibility of dry burning. It immediately alarms and automatically cuts off the power supply. The maximum temperature upper limit alarm protection function automatically alarms and cuts off the power supply when the bath temperature exceeds 105 ℃ in any situation.

Universal water bathSuitable for placing various types of vessels and samples, it comes standard with a bottom drain valve for easy liquid discharge. It can be equipped with a fully transparent or stainless steel bath cover, with high heating power and temperature control technology to ensure fast and stable reaching of the required temperature for the experiment. Place sample bottles or other containers, turn on the power, turn on the power switch, the indicator light is on, and the electric heating plate is in working condition. When the electric heating plate is in working condition, a dedicated person should take care of it. After the work is completed, turn off the power switch and cut off the power. After the working surface cools down, handle it according to the requirements. Working volume size, functional requirements (over temperature alarm, timing function, RS485, printing, sterilization system, refrigerant type), constant temperature accuracy, and display mode.
