For example, an ambient temperature of 86 F or 30 C and a process temperature of 200 C or 392 F require a heat insulator. Notes For process temperatures eratures below 29 C C or 20 F F and for guidance on the need for a heat insulator, contact your Fisher sales office. If the ambient dew point is higher than the process temperature, erature, ice might form and cause instrument malfunction and reduce insulator effectiveness.
