How does Labotronics LB-23RHB work?

Refrigerated Thermostatic Water Bath LB-23RHB system operates through three integrated mechanisms:

1. Refrigeration System
    A compressor cools the bath fluid to –20°C, enabling controlled sub-ambient operation.

2. PID Temperature Controller
    Continuously adjusts heating and cooling output to maintain ±0.1°C precision.

3. Circulation System
    Ensures uniform fluid movement to eliminate temperature gradients inside the bath.

Result: Stable, uniform, and high-precision thermal environment.
