The unit is equipped with a self-diagnostic function that stops operation and triggers an alarm when an abnormal condition is detected. A stop-valve nozzle is provided to enable external circulation. By using the optional STP-200 temperature sensor (Cat. No.113620), temperature control of external equipment is also possible.
① External temperature sensor terminal ② USB-B port ③ Stop valve nozzle
Prevents condensation during cooling water circulation and reduces loss of cooling efficiency. Tube inner diameter: 9mm / Applicable temperature range: –30 to 80°C / Pressure tolerance: 0.1MPa / Material: Chloroprene rubber.
Use when immersing flasks or other vessels in the bath. Specification: Tapered female thread Rc3/8 Cat. No. 164500
Used to control the bath temperature according to the temperature at the circulation destination. Model: STP-200 Cat. No. 113620
