Pionier 4281 is a medical paraffinic mineral White Oil containing aromates in trace elements. It is colourless, odourless, and clear.

Available in 5ltr canister

Silox is a synthetic oil belonging to the group of polydimethyl siloxane. It is colourless and clear with a weak odour.

The use of Silox is recommended when the gas should remain dry or when the gas reacts with water.

Not suitable for wet chlorine gas and butane.

Available in 200ml, 500ml, 1ltr & 5ltr

CalRiX is a completely synthetic fluid on a fluorine base. It is of low molecular weight, colourless, clear and odourless.

Because CalRiX is completely inert to most gases including oxygen, it can be used as a Packing Fluid when water or paraffin oil are not suitable. For example, when the gas needs to remain dry, and when the gas is highly reactive to water or paraffin oil.

Available in 1ltr

Advantages:

• Use under 0°C.
• Less evaporation than water due to its lower vapour pressure.
• Greater stability of the Packing Fluid level.
• Improvement in the repeatability of measurement results.
• Reduction in the required frequency of Packing Fluid level monitoring.
• The gas remains dry.
• In general, a lower chemical reactivity with water.

Advantages:

• Use under 0°C (down to -40°C)
• Less evaporation than water due to its lower vapour pressure, resulting in greater stability of the Packing Fluid level and in more consistent measurement result
• The gas remains dry
• In general, a lower chemical reactivity than water

Advantages:

• Extremely resistant even against highly aggressive gases because of CalRiX's fluorine base
• Less evaporation than water due to its lower vapour pressure, resulting in greater stability of the Packing Fluid level and in more consistent measurement result
• Very smooth rotation of the measuring drum in the Gas Meter because of CalRiX's high density and low surface tension.
