JCB4010 Low-Temperature Constant-Temperature Circulating Water Bath

Category:

The JCB4010 low-temperature constant‑temperature circulating water bath is suitable for applications in bioengineering, pharmaceuticals, food processing, chemical engineering, metallurgy, petroleum, and other fields. It provides users with a highly precise, well‑controlled, and uniformly temperature‑stable thermal environment, making it an ideal constant‑temperature bath for research institutes, universities, industrial laboratories, and quality‑inspection departments. Equipped with an air‑cooled, fully enclosed compressor unit, it features an external circulation pump that enables the creation of a secondary external temperature‑control zone. The cooling fluid within the bath can be routed externally to cool experimental vessels outside the unit. Temperature settings can be quickly adjusted via touch‑sensitive soft keys, ensuring convenient operation. A microcomputer corrects deviations in temperature readings, delivering a digital display accuracy of 0.01°C. An intelligent microcomputer‑based PID temperature controller offers precise temperature regulation, with intuitive touch‑key operation for ease of use.

Product Details

　　I. Preface

　　Dear customer, thank you very much for choosing the products manufactured by Jingzhou Chuangbo Instrument Manufacturing Co., Ltd. We are committed to providing you with the best possible service.

　　II. Overview

　　The JCB4010 low-temperature constant‑temperature circulating water bath is suitable for applications in bioengineering, pharmaceuticals, food processing, chemical engineering, metallurgy, petroleum, and other fields. It provides users with a highly precise, well‑controlled, and uniformly temperature‑stable thermal environment, making it an ideal thermostatic bath for research institutes, universities, industrial laboratories, and quality‑inspection departments. Equipped with an air‑cooled, fully enclosed compressor unit, it features an external circulation pump that enables the creation of a secondary external temperature‑control zone. The bath’s internal coolant can be routed externally to cool experimental vessels outside the unit. Temperature settings can be quickly adjusted via touch‑sensitive soft keys, ensuring convenient operation. A microcomputer corrects deviations in temperature readings, delivering a digital display accuracy of 0.01°C. An intelligent microprocessor‑based PID controller provides precise temperature regulation, while the touch‑sensitive interface ensures ease of use.

　　IV. Instrument Instructions

　　1. After unpacking the instrument, please use the packing list to verify that all components are present and that the instrument’s exterior is undamaged. Then, wipe the instrument clean and place it on a level workbench.

　　2. After the instrument has been properly positioned, add distilled water to the water bath until the water level is 2 cm below the top edge of the bath.

　　3. The upper part of the instrument houses the control box, which includes a power switch and a digital PID temperature controller. The switches manage the instrument’s power supply, temperature control, and circulation. After connecting the power, turn on the power switch to energize the unit; then, activate the temperature‑control switch to view the real-time bath temperature on the controller. You can set the desired temperature using the controller (refer to the attached instruction manual). When the bath temperature needs to be lower than room temperature, turning on the compressor will help the system reach the set point more quickly.

　　4. After using the instrument, first turn off the refrigeration and temperature control switches, then switch off the power. If the instrument will not be used for an extended period, unplug it from the power outlet.

　　V. Precautions

　　1. This instrument must be reliably grounded before use.

　　2. Keep the instrument clean; prevent oil samples and other contaminants from splashing onto it, and avoid exposure to moisture.

　　3. When the instrument malfunctions, it must be serviced by qualified personnel; do not disassemble it arbitrarily.

　　4. The chiller must not be started frequently; the interval between two consecutive starts should be at least 15 minutes.

　　5. Never operate the heater in a dry‑burn condition.
