Operating conditions: 0 to 40 °C ; up to 30 mg/l H₂O and for tube 5/a: 3 to 15 mg/l H₂O absolute humidity.

• Data below representative for use with an Accuro® pump
• Cross sensitivity for tube 3/a hydrogen sulphide in the TLV range retained in the pre-layer (does not interfere)
• For tubes carbon disulphide 5/a and 30/a it is impossible to measure carbon disulphide in the presence of hydrogen sulphide

One stroke is equivalent to a volume of 100 ±5 ml of gas passing through the tube.

The standard measuring range is calibrated at 20 °C and 1013 hPa.
