Overview
The OBC344EB is an open bath thermostatic circulator of the LABTOP brand. It features a stainless steel sink with a maximum Operating temperature of 200 ° C and a volume of 44L. The device achieves temperature control to room temperature by chilling down the coil and external circulating water. It provides an economical thermostatic test scheme and supports the option of external temperature control and circulating applications. It is suitable for temperature control, material testing, quality control and splitting of samples. It uses environmentally friendly natural refrigerants with liquid level protection and over-temperature protection. It meets Safety level III/FL. It can use flammability liquids and meets DIN 12876 standard.
Features

16. Optional 0-10V or 4-20mA analog signal input, can be used for external smart devices to control instrument start and stop
Principle
The OBC344EB open bath thermostatic circulator enables precise temperature regulation with intelligent PID control technology and a Pt100 temperature sensor. The device uses a chill down coil and external circulating water to control the temperature to room temperature, supporting external temperature control applications. Optional external circulation adapter and external temperature sensor PT100 expand external circulation and temperature control capabilities.
Applications
Sample temperature control, material testing, quality control, analysis
Steps
1. Connect the power supply to ensure that the Ambient Temperature is within the range of 5~ 32 ℃
2. Set the operation mode as needed (mode 1, mode 2 or mode 3)
3. Use the knob to set the overtemperature protection temperature
4. Optional external temperature sensor or accessories for external temperature control and circulation application
5. Start the device, monitor the temperature through the LED display, resolution 0.1 ℃
6. Optional Remote Communication interface control equipment start and stop
7. The equipment supports continuous operation and can automatically resume operation after an unexpected power failure
Notice
* Ensure Ambient Temperature in the range of 5~ 32 ℃, relative humidity does not exceed 80%
* Check the liquid level before use to avoid dry burning. The equipment has a low liquid level protection function
* Set hardware overtemperature protection to prevent accidents when the device program fails
* Power supply voltage 200~ 230VAC/50Hz to avoid mismatch
* Optional accessories need to be installed correctly to ensure external temperature control and cycle application safety
* Equipment meets Safety level III/FL and can use flammability liquids, subject to compliance with relevant safety regulations
Regularly check pumps and temperature sensors to ensure automatic adaptation to external loads and accurate temperature control
