Portable analyser for SF6 purity, moisture and decomposition products
The Rapidox 6100 Portable enables on-site verification of SF6 quality in medium- and high-voltage gas-insulated switchgear and circuit breakers.
Advantages
Straightforward operation with results in minutes
Test set-up and start are handled from the 7″ (18 cm) colour touch screen, with soft menu keys and an alphanumeric keypad. All selected gases are measured and logged simultaneously, and a stable reading is obtained within a few minutes.
Up to eight gases with a single instrument
The modular architecture supports simultaneous analysis of up to eight compatible gases: SF6, H2O (dew point), SO2, HF, CF4, H2S, CO and O2/N2 (air), depending on the requested configuration. SF6 purity is measured with an infrared sensor over 0-100 % with ±0.5 % accuracy.
Testing without gas emissions
The gas outlet nozzle allows the analyser to be coupled to a recovery bag, so the sampled gas is captured in full rather than released to the atmosphere.
Faster moisture readings
Units equipped with an H2O sensor incorporate the Rapidri drying system, which reduces the waiting time between successive dew-point readings. A dedicated valve isolates the sensor when the instrument is not in use.
Standardised tests as delivered
Current IEC and CIGRE test configurations come pre-installed and custom parameters can be defined. Results are printed on site with the integrated thermal printer or exported in MS Excel-compatible format via USB memory stick.
Applications
- Maintenance of GIS cells and circuit breakers in MV and HV substations.
- Commissioning and acceptance testing of electrical equipment to IEC and CIGRE criteria.
- Zero-loss sampling in installations where the analysed gas must be recovered.
About the product
The internal pressure of the sample is recorded together with the readings, and test locations and user names are editable, with password protection. Bespoke sensor combinations are available on request.
The equipment is housed in a heavy-duty IP66 case with a total weight of 8.5 kg. The lithium battery provides over 8 h of autonomy and charges on any mains voltage.
Available accessories: calibration kit, gas recovery bag and self-sealing couplings.

Frequently asked questions
Why does SF6 need to be analysed periodically?
SF6 is a greenhouse gas that must remain within a closed circuit. Early detection of moisture and decomposition products prevents outages and failures and reduces maintenance costs.
Is any gas lost during the test?
No. The analyser couples to a recovery bag that captures all the sampled gas.
Which test standards are included?
Current IEC and CIGRE configurations come pre-installed; custom tests can also be defined.
How are results documented?
Via the integrated thermal printer or by export to MS Excel-compatible format on a USB memory stick.
