SHEL LAB High-performance water baths are accurate, easy to use, safe and durable. The digital set / digital read P.I.D. temperature controller maximizes rapid heat-up with no temperature overshoot. A microprocessor achieves precise temperature control regardless of how the unit is loaded. Calibration is performed directly from the front panel. These durable and dependable water baths come with a variety of safety and convenience features. They have a unique lid design that allows condensation to drain back into the tank without spilling onto the work area. We have also incorporated a gasket around the water bath tank to prevent water from dripping onto the controls. A warm air jacketed design radiates heat to the sides and bottom of the tank, eliminating hot spots. Our water bath units have a non-contact, recessed heating element that will prevent burnouts if the water level in the tank is too low.
