Programmable 300 Series
• Accurate, reproducible, reliable temperature control in an easy to use unit
• Temperature sensed by a 100-ohm platinum RTD and controlled by PID controller; control to ±0.015°C from 5.0°C above ambient to 120.0°C
• A single program of up to 50 steps can be stored in memory and can be re-run by pressing a single key; steps can be stored for multiple temperature/time sequences
• Temperature can be ramped up or down at a given rate for more exacting reactions or events; ramping rates settable are 0.1°C/hr. to 150.0°C/hr., but cannot exceed the rates at which heating or cooling can occur within the physical parameters of the bath or sample
• Heater cutoff relay activated by software when water level is low, heater drive is shorted, heater is not regulating or electronic circuitry fails
300 Series Circulators and Baths feature clearly marked, logical 353 controls; 100-hour digital timer with alarm; auto-off function; audible and visual safety alarm; digital display of all key parameters; and a multi-coiled, 1000-watt heater element.
Temperature readout to 0.1°C or 0.1°F from -15.0° to 120.0°C or 5.0° to 248.0°F. Stability: ±0.02°C/24 hours. Accuracy: ±0.1°C as factory calibrated. 2.1 psi pumping pressure will pump 8 Liters/minute; head swivels 360° to direct flow away from samples. Stainless steel construction on all wetted surfaces. Circulators designed to keep corrosion from all critical parts. If necessary, the instrument can be calibrated by the user in the field with two simple potentiometer adjustments.
Supplied with a 3/8-16 threaded hole in rear of unit for mounting on a ring stand. Overall height: 12"; height above bath: 5.8"; depth below bath: 6.2". Controller is 4.5" W x 4.8" D; weight: 5.5 pounds without bath. Stainless steel baths available in various sizes with or without mounting bridges and covers. Complete with instruction manual, switched and fused AC power and three-wire grounded line cord.
