baths     high- temperature baths

feature

●        special closed-loop circulating passage structure guarantees sufficient circulation of liquid in working room, key indexes such as evenness and variation are largely improved.

●        liquid circulating device adopts gear coupling device, it is very efficient and reliable.

●        high-precision computer temperature controller is used for control of temperature in the bath through pid self calculating.

●        with functions of correcting measured temperature value.

application

●        widely used in petroleum, chemical industry, electronic instruments, physics, chemistry, biological engineering, medicine and health, life science, light industry food, physical property test and chemical analysis departments, offer a constant-temperature source with controlled heat, even and constant temperature when users are working, give test samples or produced products a thermostatic test.

●        it can be used as heating source for direct heating, to put samples directly in the bath for constant temperature, or used to directly connect with outside circulating pump according to users’ requirements.

●        especially used as constant temperature source in test of temperature change  curve with inductor, resistor and thermometer.
