Constant temperature water bath, cooling and heating circulation bath (programming type)

Intelligent programming control

• Can store 10 sets of programs (including temperature control and constant temperature control)
• Each program has 10 segments, with a control time range of 99 hours and 59 minutes for each segment.
• Each group of programs can be connected and used.
• Each program can be reused 99 times.
• Before the program starts, the preheating and heating time can be set in advance.

  Performance characteristics

• Working temperature range:
  - RW3-35PSeries temperature rangearound: Room temperature-35°C to 150°C.
  - RW3-25PSeries temperature rangearound: Room temperature-25°C to 150°C.
• Microfabrication PID Control
• Three point calibration function/automatic adjustment function/automatic operation function.
• The 5-speed dual cylinder pump and built-in condenser can circulate externally and internally, as well as reduce turbulence. (1-3 gears are internal circulation, 4-5 gears are external circulation)

  Easy to operate

• LCD touch screen display with simple and easy to understand icons and menu bar.
• Timer operation function. (1 minute to 99 hours and 59 minutes)
• The input/output signal has a chain reaction with external devices.
• The RS-232USB interface can be used for external control and data collection.
• Stainless steel bath is a one-time stamping process that is corrosion-resistant, leak proof, non angular, and easy to clean.
• Detachable condenser air filter, convenient for repairing the refrigeration part.
• Using a CFC free cooling machine (R-507, R-404A), Two spare valves are standard to prevent leakage.
• The front partition can be quickly opened to clean the condenser.
• Built in casters and side handles facilitate transportation and installation.

• Safety features

• The isolated design of the mixer, heater, and sensor (separated by shelves) can minimize the turbulence of the bath and prevent users and samples from coming into contact with it.
• The temperature alarm indicator can indicate the internal temperature status in three different light colors.
• Security protection function with alarm.
  -Prevent low liquid level and no bath operation, over temperature protection, current overload protection.
• Keyboard protection function to prevent unauthorized operations.
• The easy-to-use operation keyboard can prevent shower gel from splashing in.
