Frequently Asked Questions

How does the dual circulation system work?

The internal circulation pump maintains ±0.1°C temperature stability within the bath chamber. The external circulation pump delivers thermostatic water at 12 L/min (0.25 bar) through 9 mm hose connections to cool or heat external laboratory equipment without compromising bath temperature stability.

What is the temperature accuracy specification?

The JSRC-30C maintains ±0.1°C accuracy at 37.0°C with a digital PID controller providing 0.1°C resolution. This high precision is achieved through the motorized hermetic sealed compressor and continuous internal temperature monitoring.

Is regular maintenance required?

No. The AISI 304 stainless steel bath construction is corrosion-resistant and maintenance-free. The stainless steel pump mechanism is designed for repeated long-term use with corrosion resistance.

Can the unit calibrate its own temperature reading?

Yes. The JSRC-30C includes a built-in internal temperature calibration function. Users can verify and adjust temperature readings in the field to maintain measurement accuracy over time.

What safety features are included?

The unit features high-temperature overshoot protection, audible alarm, programmable timer, automatic PID tuning, and emergency drain valve. The hermetic sealed compressor design adds additional operational safety.

What is the external circulation pressure rating?

The external circulation pump operates at 0.25 bar pressure, delivering 12 liters of temperature-controlled water per minute through standard 9 mm hose fittings to connected laboratory devices.

Is the cooling system environmentally friendly?

Yes. The JSRC-30C uses a CFC-free air-cooled compressor, complying with environmental regulations and eliminating ozone-depleting refrigerants.
