This document describes the Nahita Thermostatic Water Baths, models 601/3, 601/5, 601/12, and 601/19. These devices are electric heating constant temperature water bath boilers primarily used in laboratories for various chemical and biological processes such as distillation, desiccation, concentration, and warm maceration. They are considered essential instruments for universities, colleges, specialized schools, and scientific research institutions.
The Nahita Thermostatic Water Baths are designed to provide a stable and controlled temperature environment for laboratory applications. Their core function revolves around maintaining a constant temperature within the water bath, crucial for precise experimental results. The devices feature an intellectual digital temperature control system that monitors and adjusts temperature fluctuations to ensure high precision. This system automatically manages the heating process, cutting off heat output if an over-temperature alarm is triggered or if the temperature sensor malfunctions. The controller also includes a timer function, allowing for timed operations or continuous running. An independent dry heating protector is integrated to prevent damage if the water bath lacks sufficient water, automatically powering off the machine in such an event. The device also incorporates safety features like overcurrent protection and an alarm for over-temperature conditions, further enhancing operational safety.
Operating the Nahita Thermostatic Water Bath involves a straightforward process. Before use, the water bath must be placed on a stable platform, and water should be added until it reaches approximately 50mm above the clapboard. It is crucial to connect the device to a power supply that matches its requirements and ensure proper grounding of the socket. Once powered on, the power supply indicator light illuminates, and the user can set the desired temperature using the digital controller. The controller then displays the temperature inside the working chamber. For timed experiments, the user can set a specific duration, after which the controller will indicate "End" and sound a buzzer. If no time is set, the device runs continuously. The controller offers both temperature and time setting capabilities, accessible via the "SET" button and adjustable with "SHIFT," "DEC," and "INC" buttons. The device also supports an auto-tuning function, which optimizes PID parameters for stable temperature control. This is initiated by pressing the "SHIFT" button for 6 seconds, allowing the controller to automatically adjust its settings. In cases of sensor faults or temperature exceeding the measuring range, the upper display window will show "---", and the heat output will be cut off, accompanied by a continuous buzzer sound and an illuminated "ALM" indicator.
To ensure longevity and reliable performance, the Nahita Thermostatic Water Baths require specific maintenance practices. After each use, it is important to timely discharge the water, dry the unit, and keep it clean. This prevents the accumulation of residues and extends the service life of the instrument. The device is constructed with a water-trough liner made from imported stainless steel, which is resistant to shock and extrusion, and its shell is made of high-quality cold rolled steel treated with plastic spraying technology, making it shiny and wear-resisting. These materials contribute to the device's durability and ease of cleaning. In the event of a dry heating protection activation, indicated by the machine powering off due to lack of water, the user needs to add water and then reset the protector by taking off the red knob and pressing the protection button. Troubleshooting common issues is also facilitated; for instance, if there's no power supply, checking the plug/socket contact or replacing a burnt fuse is recommended. If the temperature does not rise, potential causes include a broken temperature control instrument, a faulty sensor, an incorrectly set temperature, or a burnt heating pipe, each with corresponding handling methods such as replacing the instrument, sensor, resetting temperature, or replacing the heating pipe. For discrepancies between displayed and actual temperature, checking and potentially replacing the temperature control instrument or sensor is advised. Proper storage in a cool, dry environment with a temperature range of -20°C to +40°C is essential, and during handling, violent vibration and collision should be strictly avoided to prevent damage.
