  Constructional features

• Variable-speed pump for liquid viscosity for accurate, stable, and efficient temperature 
  management. (1 to 3 steps of pump for internal circulation / 4 and 5 steps for external circulation)
  
• Powerful pressure and suction pumps provide contrast pressure and flow rate throughout the 
  whole temperature range.
  
• Baffle plate screens circulating pump, heater and sensor to minimize shaking bath fluids and protect sample 
  and operators from direct contact.
  
• Dry-running protection; automated heating element cut-off and audible and visual warning.
  
• Seamless stainless steel tank with a reservoir drain that resists corrosion and make cleaning easy.
  
• Space saving design uses minimal bench space.

  1) If you operate the unit in 1 to 3 steps of pump, the temperature range can be from Amb. +5°C but in 4 and 
  5 steps, the range will be from Amb. +15°C.
  2) The heat-up time is measured on a 230V electrical condition with 1000W heater power.
