The temperature of test solution is automaticly adjusted to required temperature with a microprocessor type sensor placed in the water bath. The second sensor can be placed in the lever lid containers or stainless steel immersion container by user.The temperature data of water bath and the temperature test solution are displayed in real time on digital screen with 0.1°C resolution.

Homogenous temperature distribution can be obtain with water circulation pump that makes feedback.

Magnesium Sulfate / Sodium Sulfate Test Water Bath has (20±2) ⁰C accuracy and can be used as general purpose water bath that temperature is between 15-60 °C temperature

Supplied complete with the immersion container with the cover.
