Important Note:

The outer diameter of the glass flask may vary depending on the manufacturer. The outer diameter of the glass flask must correlate with the inner diameter of the heating jacket, otherwise it will not sit properly and may be damaged. Use only temperature control devices certified and approved for ATEX Zones. An earth leakage circuit breaker (RCD/ELCB) should be used in the electric circuit to which the heating jacket is connected.
