GT Series Multi Gas Monitor GT 40 (CH4, CO) incl. Carrying Case & Accessories

Reference: C67401

1 instrument – 7 applications Leak Test Mode – measures methane in three different distinct ranges (ppm/LEL/%Volume). Autoranging between all three ranges, audible, visual, and geiger alarms, and ergonomical design allows for easy one handed operation. Also ideal for carbon monoxide investigations.

Product description

1 instrument – 7 applications

  1. Leak Test Mode – measures methane in three different distinct ranges (ppm/LEL/%Volume). Autoranging between all three ranges, audible, visual, and geiger alarms, and ergonomical design allows for easy one handed operation. Also ideal for carbon monoxide investigations.
  2. Confined Space Mode – measures up to 4 gases (02, LEL, CO, H2S) simultaneously with audible visual alarms, datalogging, and min/max values.
  3. Barhole Mode – for testing underground gas leaks. In this mode the GT measures gas beginning in the LEL range and autoranges to % Volume. Barhole probe included with instrument.
  4. Carbon Monoxide Mode – measures CO directly in ppm. Menu items for air free CO (02 correction) when fitted with an 02 sensor, and differential CO.
  5. Purge Mode – for measuring methane from 0–100% Volume in inert atmospheres.
  6. Sniffer Mode – enables rapid leak detection by measuring methane from 0–10,000ppm with the semi-conductor fitted at the end of the flexi probe. Audible/visual geiger allows for easy pinpointing of leaking pipes.
  7. Pressure Mode – measures from 0–60” of water column via a pressure sensor on the back of the instrument. Ideal for tightness tests on gas systems up to 2 psi.
