CATHARO_VAL

Self-contained helium measurement system - HELIUM portable sniffer

réf : C-102

The portable catharometer is a robust device for helium sniffing measurements. Particularly appreciated by operational teams during tests and qualifications, the PORTABLE CATHAROMETER is delivered in a rigid case with its accessories. It offers the following functions:

• Digital display for 0-100% scale.
• Bargraph display for 0-10% scale.
• ppm / % conversion.
• Self-check and auto-zero on power-up.
• LED helium presence display.
• Integrated pump with protective filter.
• Display of sensor and pump faults.
• Autonomy: 4 hours in continuous mode.
• Standby mode.
• Trigger-operated pump start.
• Precision adapter for leak detection.

ATEX Catharometer

C100 ATEX

This rugged Catharometer sensor is designed to measure the concentration by volume of a gas in a binary mixture.

This non-selective ATEX sensor is designed to measure the thermal conductivity of gases.

The main applications are gas measurement:

• Hydrogen
• Helium
• Methane
• Carbon dioxide

Presented in an explosion-proof aluminum case, two versions are available:

• 4-20 mA 3-wire output version.
• BRIDGE version with 100 mV output.

Flow-through catharometer

C101

This rugged catharometer is designed to measure the volume concentration of a gas in a binary mixture.

This non-selective sensor is based on the measurement of the thermal conductivity of gases.

The main applications are the measurement of :

• Helium
• Carbon dioxide

Presented in an aluminum case, this sensor is directly integrated into a circulation tank:

• Connections are made via a screw terminal block inside the case.
• Inlets and outlets are designed for semi-rigid 4 x 6 mm tubing.
