The Hyoda S6 is a fluid-filled thermometer with a 150 mm dial and remote sensing bulb connected by capillary tube.
The Hyoda S6 is a wall-mounted thermometer with a 150 mm dial and a sensing bulb connected by capillary tube. This arrangement allows the display to be installed away from the measurement point, where it is easier to read.
Select an indication-only version or a configuration with pointer contacts for a compatible alarm or control circuit. The S6 uses a fluid-filled measuring system; for a bimetal alternative, see the AY Series comparison below.

The Fluid-Filled Thermometer Range is an overview listing, not a single model with one specification. Compare the exact model, temperature scale, sensing bulb, connection and mounting before ordering. S6 and M6 both have 150 mm dials, but this does not establish interchangeability.
Contact Seacom with your temperature range, sensing bulb dimensions, connection, capillary length and contact requirements. For a replacement, include photographs of the instrument nameplate and installation so we can help check the appropriate configuration.
