          *1 The EG-547(W) cannot be used in combination with SH-422, 430, 440, 290, 809, 816 and 822.
          *2 Precautions when using heat-resistant sensor head:
          Use the sensor within the stable detecting range.
          The heat-resistant sensor head is not waterproof; do not use this sensor head in a location directly exposed to liquid or steam.
          *3 Above values obtained when the detecting distance is set at 50% of the maximum stable detecting distance.
