• *Frozen machine doesn't work at a liquid temperature of 40? or higher.
• *Please avoid continuous operation at high temperature range (80? near).
• *Circulation pump performance is the value when using pump single.
• Provides improved cooling capability due to adoption of high performance refrigerator.
• Supports pure water*#?1#* because SUS304 square coil is used for circulation water cooler.
• Adopts R-404 refrigerant with zero ozonosphere disruption potential for environment protection.
• External circulation nozzle is located on the front of controller, which can be rotated to any direction within range of 180?.
• Adopts PV?SV dual display system for temperature setting display which allows user to confirm measured value and set value at a glance.
• SB(support rod?bracket set) can be used to clamp flask or external sensor inside water bath.?1 When using pure water, make sure that electric conductivity is 10*u*S/*cm*(proximate purity).
