• Programmable functions for versatile applications
♦ Wide Temperature Range Control: Ensures precise regulation within ±0.03°C across a broad range.
♦ PC Connectivity: Includes measurement and control software for processing temperature trend data when connected to a PC.
♦ Precision Temperature Programming: Supports accurate temperature ramping and cooling with up to 7 user-defined patterns (each with up to 10 segments) and enables pattern linking.
♦ User-Defined Program Options: Allows selection of post-program actions: stop, maintain final temperature, or return to initial settings.
• Intuitive control panel
Program parameters can be easily set using the numeric keypad.
• Programmable operation modes
| User Programs |
 |
| Type A (3 patterns): Stops operation after the program ends. Type B (4 patterns): Activates standby mode to maintain the final temperature after the program ends. In Type B mode, the standby function allows use of the SKIP/END feature to reset the system to its initial temperature and maintain that condition. After loading a new sample, simply press the key to restart the program, enabling seamless repeat operations. |
• PC interface and external circulation functionality
The NCB series features an RS-232C interface, allowing temperature control via an external host PC.A stop valve nozzle is provided for external circulation. Supports optional external temperature sensors to control target device temperatures, ensuring stable and precise operation in connected systems.
• Remote operation and data processing via dedicated software
♦ Control software ESMon2018
Temperature can be remotely controlled via RS-232C communication, and trend data can be processed using the software.
Note: Only supported in normal mode. Program mode is not supported.
| Operating system | Microsoft Windows® 10 |
| CPU | Pentium or higher (Pentium III 800MHz or higher recommended) |
| Hard disk | A minimum of 15MB of free disk space is required. Additional storage capacity may be necessary for data recording. |
| Memory | Requirements vary depending on the operating system, but 128 MB or more is recommended. |
| Communication interface | A serial interface (COM1, etc.) is required. If you are using a computer that does not have a serial interface, please use a commercially available “USB-serial conversion cable.” |
