Confined space gas monitor with pump
The Riken Keiki GX-2012, Confined space gas monitor with pump, has multiple functions in one instrument. It has 3 operating modes. Customers can use the GX-2012 for confined space monitoring, leak investigation in addition to underground leak checking when in Bar Hole mode.
When selecting a flammable gas monitor, it is important to understand different sensor types and how they measure different conditions. Many Gases are flammable within a range of concentration known as the explosive or flammable range.
There are two limits to this range the lower explosive limit (LEL) and upper explosive limit (UEL). The Range differs
Catalytic Bead (CB) :
CB type sensors are intended for use below the LEL and are typically scaled from 0-100 % LEL. The full-scale indication
Thermal Conductivity (TC) :
TC sensors do not require oxygen to operate. The most notable advantage of the TC type sensor is
The GX-2012 Confined space gas monitor with pump includes both catalytic bead and thermal conductivity sensors. These will automatically switch from a % LEL to a % Volume range.
Most dual range combustible instruments do not have the ability to automatically select the appropriate sensor. It is important to use the correct sensor based on the gas concentration being encountered. If the instrument does not auto-range like the GX-2012, then the user must manually select the range. This may result in the user getting inaccurate readings or damaging the catalytic bead sensor.
When the GX-2012 detects high levels of methane, the display automatically changes from the % LEL to the % Volume. This is ideal for line purge testing. In
The GX-2012 is built around high-quality micro-sensor technology, the GX-2012 is Riken Keiki’s smallest personal 1-5 sensor gas monitor with a
The GX-2012 has a large LCD display that shows all gas readings, battery level and
