Overview
The LABTOP BC213E bath thermostatic circulator is a thermostatic circulator with a heating head. With the help of external circulating water or chilled down liquid tanks, the temperature can reach room temperature or -20 ° C. The bath body is made of all stainless steel and filled with aluminum silicate cotton insulation, providing an economical solution for the sample to be placed directly in the water bath for thermostatic testing. The optional external circulation adapter and external temperature sensor PT100 can realize external temperature control and recycling applications. It is suitable for sample temperature control, material testing, quality control and analysis. It uses environmentally friendly natural refrigerants with liquid level protection and over-temperature protection functions.
Features
1. Hardware over-temperature protection, users can set the protection temperature through the knob, and dry burning can still be avoided when the equipment program fails. It meets the DIN12876 standard level III and can use flammability bath liquid.
2. Maintenance-free pressure/suction pump, pump pressure and Flow rate automatically adapt to external load.
3. Optional multi-stage programmable controller, support multi-stage program control, such as regular heating, cooling, thermostatic, slope and each period of time, each program can be set to run up to 999 hours.
4. Equipped with external temperature sensor interface, optional movable external temperature sensor, combined with PID TAC control technology, Cascade cascade control technology and bath internal and external temperature lock control technology, precise control of bath external material temperature.
5. Pt100 temperature sensor, supports single point, two point and multi point temperature calibrating.
6. Parts that come into contact with liquids or vapors are made of high-performance stainless steel and high-performance plastics.
7. Optional related accessories can be used to form different internal and external applications.
8. The buzzer can be set to silent or audible.
9. A variety of operation modes are optional, and accidental power failure can be automatically restored, including mode 1 (power-on equipment stops after power failure, setting value can be changed), mode 2 (power-on automatic operation after power failure, setting value can be changed), mode 3 (power-on automatic operation after power failure, setting value cannot be changed).
10. The device serial number can be queried through the software.
11. Optional intelligent control function, support a variety of interfaces (RS485, RS232) to achieve remote communication and control equipment start and stop.
12. Optional normally open and normally closed 2 external contact points, can be connected to external alarms.
13. Optional set of 12V switch Output signal for controlling external solenoid valve.
14. An optional set of 5V external input switch signals can be used for external smart devices to control the start and stop of the instrument.
15. Optional 0-10V or 4-20mA analog signal input for external smart devices to control the start and stop of the instrument.
Principle
The BC series thermostatic circulator realizes temperature control through the heating head and chill down coil. With the help of external circulating water or chill down liquid tank, the temperature can reach room temperature or -20 ° C. The water bath body is made of stainless steel and aluminum silicate cotton insulation to ensure a thermostatic environment. Optional external circulation adapter and external temperature sensor PT100, combined with PID TAC control technology, Cascade cascade control technology and bath internal and external temperature difference lock control technology, achieve precise temperature control.
Applications
Sample temperature control, material testing, quality control, analysis
Steps
Connect the power supply to ensure that the voltage is within the range of 200 to 230VAC/50Hz.
2. Set the temperature parameters as needed, and use the knob to set the overtemperature protection temperature.
3. Optional external Sensor or accessories can be connected to the external circulation system.
4. Start the device and select the operation mode (e.g. mode 1, 2 or 3).
5. Monitor temperature fluctuations and pump operation status to ensure normal Flow rate and pressure.
6. After use, turn off the device and disconnect the power.
Notice
• Ensure that the Ambient Temperature is within the range of 5~ 32 ° C and the relative humidity does not exceed 80%.
• Avoid the equipment from dry burning when the program fails, and use the hardware over-temperature protection function.
• Safety level III must be met when using flammability bath.
• The pump connection interface is M16x1mm to ensure that the external load matches.
The equipment is fixed to the Benchtop and allows for 100% continuous operation, but the liquid level and temperature need to be checked regularly.
• When selecting external alarms and solenoid valves, connect them correctly to avoid misoperation.
• When controlling remotely, ensure that the interface connection is stable to prevent communication interruption.
