The OBC344B is an open bath thermostatic circulator of the LABTOP brand. It uses a stainless steel water bath with a maximum Operating temperature of + 220 ° C and a Tank volume of 44L. The device is cooled to room temperature by means of an external circulating water through a built-in chill down coil, providing an economical solution for placing samples directly in the bath for thermostatic testing. It is suitable for temperature control, material testing, quality control and chemical analysis of samples, and has liquid level protection and over-temperature protection. It meets the DIN 12876 standard Safety level III and can use flammability liquids.
1. Equipped with low liquid level protection function to prevent dry burning. 2. Equipped with hardware over-temperature protection, the user can set the protection temperature through the knob, and still provide protection when the program fails. It meets the DIN12876 standard level III and can use flammability bath liquid. 3. Adopt maintenance-free pressure/suction pump, pump pressure and Flow rate automatically adapt to external load. 4. Optional multi-stage programmable controller, support timing heating, cooling, thermostatic and slope control, each program can run up to 999 hours. 5. Equipped with external temperature sensor interface, optional mobile external temperature sensor, combined with PIDTAC control, Cascade cascade control and bath temperature difference lock control technology, precise control of external material temperature. 6. Adopt Pt100 temperature sensor, support single point, two point and multi point temperature calibrating. 7. Parts that come into contact with liquids or vapors are made of high-performance stainless steel and high-performance plastics. 8. Optional accessories can be used to form different internal and external applications. 9. The buzzer can be set to either sound or silent mode. 10. Provide a variety of operation modes, which can be automatically restored after accidental power failure (mode 1: power-on equipment stops after power failure, and the set value can be changed; mode 2: power-on automatic operation after power failure, and the set value can be changed; mode 3: power-on automatic operation after power failure, and the set value cannot be changed). 11. The device serial number can be queried through the software. 12. Optional intelligent control function, providing a variety of interfaces (e.g. RS485, RS232) for remote communication and control. 13. Optional normally open and normally closed 2 external contact points for connecting external alarms. 14. Optional with a set of 12V switch Output signal, used to control the external solenoid valve. 15. A set of 5V external input switch signals can be selected for external smart devices to control the start and stop of the instrument. 16. Optional 0-10V or 4-20mA analog signal input is available for external smart devices to control the start and stop of the instrument.
The OBC344B open bath thermostatic circulator uses intelligent PID control technology to precisely monitor the temperature of the medium in the bath with the Pt100 temperature sensor. The equipment has a built-in heating system to heat up and is cooled down by external circulating water through a chill down coil, thus achieving precise control from room temperature to set temperature. Its pressure/suction pump automatically adapts to external loads, ensuring stable Flow rate and pressure of medium circulation, providing a uniform, constant temperature environment for samples placed in the bath or circulated externally.

DIN 12876
1. Place the device on a stable table and connect it to a power supply (200~ 230VAC/50Hz). 2. Add an appropriate amount of working medium (water or oil) to the stainless steel bath to ensure that the liquid level meets the requirements and to avoid dry burning. 3. Optional and connected external circulation adapter, external temperature sensor PT100 or Miscellaneous accessories. 4. Turn on the power supply of the equipment, and set the required temperature, protection temperature, and Miscellaneous operating parameters (such as program segment, time, etc.) through the control panel. 5. Start the circulation pump and heating/chilling down system, and the equipment starts to work. 6. Place the sample to be tested in the bath or connect it to an external circulation circuit. 7. Monitor the operating status and temperature display of the equipment, and turn off the power of the equipment after the experiment is completed. 8. Empty the bath and clean the equipment.
• Permissible Ambient Temperature of the equipment is 5~ 32 ℃, relative humidity ≤ 80%, please ensure that it is used in a suitable environment. • Before use, please confirm that the Power supply voltage is 200~ 230VAC/50Hz and ensure good grounding. • When adding medium to the bath, please pay attention to the liquid level to avoid triggering protection or causing dry burning when running at a low liquid level. • When using flammability bath, ensure that the equipment is under safe operating conditions in accordance with DIN 12876 Class III. When the equipment is running, do not touch the high-temperature medium or heating parts in the bath to prevent burns. • Regularly check the chill down water connection to ensure that the chill down coil can work effectively. • When calibrating the temperature, use a qualified Pt100 temperature sensor and follow the procedure. • Before moving or cleaning equipment, be sure to disconnect the power and wait for the equipment to completely chill down. • If the equipment is not used for a long time, please empty the medium in the bath and keep it drying.
