HELIUM LEAK DETECTOR

MSE-2000A

MSE-1001

The MSE-2000A model is a full automatic portable helium leak detector. It uses a molecular drag pump with a high compression ratio and high performance analyzer tube to achieve high sensitivity and low background.
MSE-2000A DRY utilizes a diaphragm vacuum pump for the roughing pump and other models are also available.

Main features

  • Quick recovery from high background.

  • By the automatic sensitivity calibration, a leak test is available approx. four minutes after power-on.

  • Variable leak tests are possible with combination of sniffer unit and roughing unit.

  • Equipped with two pieces of long life thorium oxide-coated iridium filaments.

  • This equipment has an audio alarm function which produces various timbres from a digital sound source.

  • A 12x9cm large size LCD touch panel enables intuitive easy operation.

  • The new type CPU board make the change of the LCD display faster and improve operability.
