RW3-0535 Refrigerated, Heating Bath Circulator (5L), 230V

RW3-0535 Refrigerated & Heating Bath Circulator (5L), 230V

The RW3-0535 is a high-performance refrigerated and heating bath circulator engineered for applications requiring precise and stable temperature control over a wide range. Its powerful circulation and rapid heating and cooling capabilities make it an ideal companion for instruments like refractometers and viscometers, ensuring accurate measurements even at temperatures as low as -35°C.

Performance & Precision

• Wide Temperature Range: Operates from -35°C to 150°C (-31°F to 302°F), providing versatility for a variety of laboratory applications.
• Exceptional Stability: Maintains temperature with a stability of ±0.05°C, thanks to advanced microprocessor PID control.
• High Cooling Capacity: Delivers robust cooling power where you need it most: 80W at -20°C, 150W at 0°C, and 280W at +20°C.
• Optimized Circulation: Features a five-speed adjustable pump to minimize turbulence. Use lower speeds (1-3) for gentle internal circulation or higher speeds (4-5) for powerful external circulation.
• Intelligent Calibration: Includes three-point temperature calibration and an automatic tuning function for superior accuracy.

User-Friendly Operation

• Intuitive Interface: A bright VFD display and a quick-adjustable dial knob allow for easy setting and monitoring with a 0.1°C resolution.
• Programmable Timer: Dual wait on/off timer modes can be set from 1 minute up to 99 hours and 59 minutes for automated workflows.
• Convenient Memory: Instantly recall up to three of your most frequently used temperature settings.
• Effortless Maintenance: The corrosion-resistant stainless steel bath is designed with rounded corners for easy cleaning and a front-access drain valve. A detachable condenser air filter and a quick-release front grill make routine upkeep simple.
• Remote Connectivity: An RS-232 interface is included for external control and data logging (RS-232 to USB converter provided).

Built for Safety and Durability

• Isolated Design: A baffle plate isolates the agitator, heater, and sensor, protecting samples from turbulence and users from direct contact.
• Comprehensive Alarms: A complete safety system provides audible and visual warnings for low fluid levels, dry-running conditions, over-temperature, and over-current.
• Keypad Lock: Prevents accidental setting changes during critical operations.
• Eco-Friendly & Leak-Proof: Uses CFC-free refrigerants (R-507, R-404A) and is equipped with a double service valve to prevent leaks.
