The HMP378H probe option is a variant of the standard HMP378, designed for measurements in JET A-1 fuel (typical ppm accuracy: ±15 % of the reading). The mechanics of the probe are the same as in the standard HMP378 probe option (see HMP378 probe for pressurized pipelines).
HMP378H uses the HUMICAP® 180L2 sensor designed specifically for oil and fuel measurements. For HUMICAP 180L2 sensor specifications, see GUID-41785706-37E9-43B4-8F23-99B1C88AD0AC.html#GUID-41785706-37E9-43B4-8F23-99B1C88AD0AC__GUID-D5A84A48-4462-4B07-936E-82F30FF5428C.
