baths low-temperature baths

feature

● a big-size open bath is offered for direct control of sample’s temperature.

● very creative structural design guarantees higher temperature evenness and variations.

● forced air-cooled type fully-closed compressor unit is used for cooling, the cooling rate is high.

● special pid controlled high-precision instrument used to guarantee the precision of temperature control.

● operate by pressing keys, temperature can be quickly set, operation is convenient, learning is easy.

application

1.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.

2.especially used as constant temperature source by temperature sensor, thermocouple, varistor, thermistor, thermometer, inductor enterprises, used for product test, calibration and verification.
