Rapidox SF6 6100 Bench — Benchtop and Rack-Mount SF6 Analyser

Laboratory-grade Rapidox SF6 6100 Bench for precise moisture, purity and decomposition analysis.

Overview

The Rapidox SF6 6100 Bench is a fixed SF6 analyser from the British company Cambridge Sensotec. It is used where gas is analysed at a permanent workstation: utility laboratories, SF6 equipment factories, reclaim and cylinder-filling areas, and research.

Two versions are available: benchtop with a swing handle, and 19-inch rack mount for industrial cabinets. It runs on mains power; there is no battery.

What it measures

Parameter	Range	Accuracy
SF6	0–100 %	±0.5 % FS
H₂O (dew point)	-60 to +20 °Cdp	±2 °Cdp of reading
SO₂	0–100 to 0–2000 ppm	±2 % FS
HF	0–10 or 0–20 ppm	±2 % FS
CF4	0–80 %	±1 % of reading (calculated)
H₂S	0–200 to 0–2000 ppm	±2 % FS
CO	0–500 to 0–5000 ppm	±2 % FS
Air (via O₂)	0–100 %	±5 % FS

The sensor set is chosen for the task. Not every combination is possible because of cross-sensitivity, so the configuration is agreed with the manufacturer.

Sampling

• Pressurised. Gas from a compartment or cylinder at up to 10 bar flows through on its own; the pump is off.
• Atmospheric or below. The optional pump (up to 1 L/min) is switched on.
• Flow is set with a rotary knob on the front panel and shown on screen.
• Modes: timed or continuous sampling.
• Spent gas leaves through an outlet nozzle to a recovery bag or a standard reclaim system.

Integration

• programmable 4–20 mA and 0–10 V analogue outputs;
• programmable alarm relay circuits;
• RS232 (RS485 option), on-demand data streaming, Modbus RTU / Ethernet;
• Excel export via USB stick;
• password protection, Rapidox data-logging software;
• optional thermal printer.
