The liquid calibration bath uses liquid, molten salt or molten pure metal as the medium, through the action of temperature control system and stirring or spraying device. Reach the set temperature and maintain uniform temperature in its inner working area. It is mainly used to detect and calibrate the constant temperature equipment required for various thermometers or other measuring instruments.

The commonly used media for liquid calibration baths are water, silicone oil, antifreeze, absolute ethanol, tin, salt, etc., which respectively constitute alcohol low-temperature calibration baths, water baths, oil baths, tin baths, and salt baths.

The medium used in liquid calibration baths at general temperatures is generally water or silicone oil, and the temperature range is 70℃-300℃;

The medium used in the cryogenic liquid calibration bath is generally antifreeze and absolute ethanol, and the calibration temperature range is -80℃-100℃ ;

The medium used in the high-temperature liquid calibration bath is generally a special medium such as tin and salt, and the calibration temperature range can reach up to 500℃ or even higher.

The special special medium used in the ultra-low temperature liquid calibration bath, the calibration temperature range can be as low as -180℃ or even lower.

The liquid calibration bath using silicone oil as the medium will volatilize and emit smoke when it is heated, which will not only pollute the environment, but also affect the health of the staff. Some liquid calibration baths have an active smoke exhaust function (such as the DTS-CT Intelligence calibration bath series), which can avoid the above-mentioned pollution. They are environmentally friendly products and have broad market prospects.

Limited by the heating medium and its own material and structure in the liquid calibration bath, the maximum working temperature generally does not exceed 300°C; the minimum working temperature of the low temperature calibration bath is generally -80°C. If you need an ultra-high temperature or ultra-low temperature calibration bath, you need to make a special order. For example, the working temperature of the heat pipe calibration bath can reach 300 ° C ~ 500 ° C or even higher, and the temperature field uniformity is better than 0.05 ° C. It cannot be achieved by other constant temperature equipment at present.The working temperature of the ultra-low temperature calibration bath can reach -160°C to -180°C or even higher. If you need, you can leave a message below or call us directly to get the detailed parameters and prices of the relevant calibration bath.

DTS-CT Intelligent Liquid Calibration Bath is the latest temperature calibrator from Deato. It uses a large capacitive screen for intelligent control, fully intelligent human-computer interaction interface, supports multi-touch, multi-function window display, and the control is more convenient, simple and practical. This calibration bath adopts the technology of dual-chamber side stirring technology, and through intelligent PID adjustment, the constant calibration bath can achieve an ideal uniform temperature field, which can meet the requirements of low-temperature thermocouples, industrial thermal resistance, pressure thermometers, bimetal thermometers, glass liquid thermometers, etc. Verification and calibration of various temperature sensors.
