The Z615 Thermoregulator provides precise temperature control of liquid samples measured by the Qubit fluorometers (Z600 and Z620) or Z700 Thermoluminescence System. The Thermoregulator controls the temperature in the range of 0°C to +70°C with an accuracy of 0.1°C.

The Z615 Thermoregulator can work in two modes – constant and temperature ramp mode. In the constant mode, the instrument maintains a constant temperature of the measured sample. The temperature ramp mode enables linear increasing of the temperature with a uniform rate. The temperature can be set either manually or it can be controlled by the Fluorometer Control Unit. The function of the Thermoregulator can be enhanced with the Qubit Magnetic Stirrer.

The Thermoregulator consists of two parts – Thermoregulator Control Unit and Temperature Controller.
