The HoloStim-3D seamlessly integrates with the HyperScope, an award-winning multiphoton imaging system, to create an industry-leading spatial light modulator (SLM) system for all-optical interrogation of neural networks with previously unachievable performance.
npi electronic TC-20 Temperature Control System
Designed for heating two independent channels in electrophysiological experiments.
Guarantees low noise operation
Special protection features
Prevents the preparation from damage
Built in cooling elements for power devices
This device controls two independent heating channels and is housed in 19" standard cabinet.
Each system incorporates two electronic thermometers for small temperature sensors (standard is R2252, i.e. the sensor has a resistance of 2252 Ohms at 25 °C or optional PT100, i.e. the sensor has a resistance of 100 Ohms at 0 °C), two digital temperature displays (XX.X °C), a set-point control with direct readout (XX.X °C), a PI (proportional-integral) controller with adjustable parameters, an output power control unit and a high-power output stage (DC, continuous operation) for resistive (i.e. heat only) loads with electronic protection circuits.
The power outputs are short circuit protected, the output power is limited electronically. The maximum output voltage is approximately 12 V, the current is limited to 2 A.
The TC-20 controller is delivered with a power cord and a user manual. Sensors must be purchased separately.
