For an HRS series thermo-chiller set to 30℃, what are the possible causes of an unstable circulating fluid temperature? The installation environment and power supply are within the specifications.

If operation is stable, the temperature stability is ±0.1℃ (outlet temperature when the circulating fluid discharge port and return port are directly connected).
In some cases, if the circulating fluid flow rate is insufficient, it may prevent the temperature from stabilizing.
Another possible cause is an excessive amount of piping resistance that makes it is difficult to secure the flow rate. Also, if there was no problem before, check if the flow rate has decreased due to clogging of the filter, etc. If the circulating fluid falls below the rated flow rate, it may cause a drop in the cooling capacity of the thermo-chiller or a decline in temperature stability.
In this case, use the bypass piping set (optional accessory) to secure the flow rate.
Note) The temperature stability is as follows: ±2.0℃ for the HRSE, ±0.5℃ for the HRS090, and ±1.0℃ HRS100/150/200.
