Condition: used, This listing is for the LEEC P33 Mk 11 Proportional Temperature Controller The unit is in full working condition and is ready for immediate use LEEC P33 Mk 11 Proportional Temperature Controller (Precision Incubator) This unit is a microprocessor-based PID (Proportional‑Integral‑Derivative) temperature controller, designed to deliver exceptionally stable temperature regulation within the LEEC P33 Precision Incubator. Key Features & Performance Highly Accurate Regulation: Maintains temperature within ±0.1 °C at 37 °C—ideal for sensitive biological and laboratory applications. Dual Temperature Display: Clearly shows both the user-set "target" and the current "actual" temperature on a digital LED display, with indicators for when heating is active. Proportional (PID) Control: Employs PID control through low-wattage heating elements profiled to avoid hot spots. This ensures smooth transitions and precise thermal stability. Fast Recovery & Uniformity: Recovery Time: Approximately 6 minutes to return to set temperature after door opening. Uniformity: Achieves ±1.0 °C variation across the chamber. Fan-Assisted Circulation: Twin fans create gentle, full-width airflow; fans automatically shut off when the door opens to reduce heat loss. Safety Cut-Out: A digitally adjustable over-temperature safety cut-out prevents accidental overheating; visual indicators and alarms streamline monitoring. Context: P33 Precision Incubator Specifications Temperature Range: From at least 5 °C above ambient up to +60 °C. Capacity & Construction: Chamber Volume: 730 litres, built from stainless steel. Dimensions: External—1550 × 1270 × 660 mm; Internal—1275 × 1140 × 490 mm. Weight: 225 kg. Bjdpfoxhfi Rjx Aa Iewu Mobility: Castor wheels are included—lockable for stability. Power: 600 W rating for heating operation. Optional Accessories: Additional shelves (L3) Internal power point (PP) External cooling unit required for operation near or below ambient temperature (e.g., LEEC recirculating cooler) Summary The LEEC P33 Mk 11 proportional (PID) temperature controller offers precise, stable, and responsive control—maintaining ±0.1 °C at 37 °C with fast recovery and uniform temperature distribution. It features handy dual displays, safety cut-outs, and is complemented by a robust chamber design. Perfectly suited for high-demand laboratory and incubation applications.
