What is the primary function of a proportional temperature controller like the P33 Mk 11?

Its primary function is to maintain a highly stable and accurate temperature within a connected thermal processing unit, such as an incubator, by precisely regulating heating elements.

Can this controller be used with any incubator?

While it is designed for the LEEC P33 Precision Incubator, its compatibility with other incubators would depend on the specific heating element and sensor interfaces of the alternative unit. Buyers should verify compatibility with their existing equipment.

What are the benefits of PID control?

PID control offers superior temperature stability and faster recovery times compared to simpler on/off controllers. It minimises overshoot and undershoot, crucial for sensitive applications.

How do I set the desired temperature on this unit?

Temperature setting is typically done via digital controls on the front panel, allowing users to input the target temperature which is then displayed alongside the actual chamber temperature.

What maintenance is typically required for a temperature controller?

Routine maintenance usually involves keeping the unit clean and ensuring proper ventilation. Periodic calibration checks may be recommended to maintain accuracy, depending on application requirements.

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.

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.
