baths calibration baths

feature

l using high-precision computer temperature controller with high temperature-control precision and high setting and display resolution.

l special structural design, making products more in conformity with scientific theory of fluid dynamics and different indexes of products better guaranteed.

application

1. used for calibration and scaling of first and second-class thermometer.

2. necessary calibration equipment for production, scientific research, especially measuring departments.

3. necessary production and testing equipment for thermometer, thermocouple, precision resistor, precision inductor manufacturing enterprises.
