YAMATO Precision Thermostatic Box DF411C/611C, DH411C/611C
High precision heat treatment constant temperature box
Product details

Thermostatic box for high-precision heat treatment.


characteristic:

Easy to operate, capable of running at a fixed value, running programs, quickly and automatically stopping, stopping, and starting operations.

Digital settings can be achieved through dedicated function menu keys and up and down keys. A program controller with repeating function, divided into 3 segments and 30 steps.

Through the auxiliary menu key, operations such as over lift preventer, deviation correction, and key lock setting can be achieved.

The exhaust damper allows for rapid exhaust and cooling inside the box.


Security and Protection

● Equipped with self diagnostic circuit (temperature sensing abnormality, heater disconnection, automatic over rise prevention, SSR short circuit), over rise protector, leakage protection switch to prevent overcurrent, button lock and other safety functions.
