thermostatic bathThe temperature control accuracy typically ranges from ± 0.01 ℃ to ± 0.1 ℃, depending on the equipment type, technical configuration, and application scenario.

　　thermostatic bathAccuracy analysis:

1、 Core accuracy range

Conventional constant temperature bath

The temperature control accuracy is generally ± 0.1 ℃, which is suitable for most laboratory basic experiments and industrial scenarios (such as chemical reaction temperature control, material testing, etc.).

For example, ordinary constant temperature water baths, oil tanks, etc., with temperature fluctuations within ± 0.1 ℃.

High precision constant temperature bath

Adopting advanced technologies such as microcomputer PID control and imported platinum resistance temperature measurement, the temperature control accuracy can reach ± 0.01 ℃, or even lower (such as ± 0.005 ℃).

For example, precision constant temperature water tanks, high-precision constant temperature water oil tanks, etc. are widely used in scientific research, biological sample preservation, metrological calibration and other fields.

2、 Key factors affecting accuracy

Temperature Controller

High precision controllers (such as PID microcomputer self-tuning) can quickly respond to temperature changes, reduce overshoot and oscillation, and improve stability.

For example, a constant temperature bath with self-tuning PID regulation can control temperature fluctuations within ± 0.01 ℃.

Heating/cooling system

Power matching needs to be reasonable: insufficient power can lead to slow heating, while excessive power can easily cause temperature overshoot.

Refrigeration technology: Low temperature constant temperature bath (such as -30 ℃ to 100 ℃) requires compressor refrigeration, combined with efficient stirring system to ensure temperature uniformity.

Blender efficiency

Efficient stirring can make the temperature of the medium in the tank consistent and eliminate thermal gradients. For example, a magnetic stirring pump can improve temperature uniformity to ± 0.05 ℃.

temperature sensor

Imported platinum resistance temperature sensors have high sensitivity and fast response, which can reduce measurement errors.

For example, the constant temperature bath for platinum resistance temperature measurement has a temperature display resolution of up to 0.001 ℃.

Tank material and insulation performance

Stainless steel liner+high-quality insulation layer can reduce heat loss and minimize environmental temperature interference.

For example, a thermostatic bath with a fully enclosed stainless steel tank has smaller temperature fluctuations.

medium characteristics

The medium has a large heat capacity and good fluidity (such as low viscosity silicone oil), which can improve temperature control sensitivity.

For example, when silicone oil is used as a medium, the vertical uniformity can reach ± 2 mK at 100 ℃.
