Riken Keiki GX-2012 Confined Space Monitor

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 for each flammable gas. At concentrations below the LEL, the mixture is too lean (insufficient fuel with respect to oxygen) to sustain combustion. In Addition at concentrations above the UEL, the mixture is too rich (too much fuel with respect to oxygen) to sustain combustion. 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 Addition the catalytic sensor is protected from being exposed to a concentrated sample of methane that is well over scale. This auto-ranging combustible capability provides users with the flexibility to do general-purpose safety monitoring as well as detection of very high levels of flammable gases without any extra precautions or procedures. 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 built in sample pump. Weighing only 350 grams, the GX-2012 can monitor the standard confined space gases (LEL combustibles, Oxygen content, Carbon Monoxide, and Hydrogen Sulfide). The GX-2012 has a large LCD display that shows all gas readings, battery level and current time. In addition the screen will automatically back-light in alarm conditions. Users benefit from all Standard alarm types include vibration, visual in addition to audible alarms. the GX-2012 continuously checks itself for sensor connections, low battery, circuit trouble, low flow, and calibration errors. The GX-2012 operates with either Alkaline or Lithium Ion batteries. Users can change the battery packs without any special tools .

Riken Keiki GX-8000 Multi Gas Detector

The GX-8000 confined space monitor sets a new industry standard for rugged, reliable, portable gas detection. This robust, lightweight, sample drawing multi-gas monitor is designed to provide continuous and simultaneous exposure monitoring in hazardous areas. It measures flammable, oxygen(O2) and toxic gases ,carbon monoxide (CO) and hydrogen sulphide (H2S) ) in air. The 0-100% volume Thermal Conductive sensor allows monitoring of volume levels of combustibles in oxygen-depleted as well as inert gas atmospheres. This combination of sensors makes for a versatile detector. It is suitable for dual-use applications such as Confined Space as well as Purging or Inerting. It’s rugged IP-67 waterproof design makes it well suited to harsh, tough environments. The GX-8000 is suitable for industries including oil and gas, utilities, waste water treatment, telecommunications as well as marine shipping. The compact, lightweight design makes it comfortable to carry using the shoulder/neck strap, and the optional waist strap allows for hands free use. The instrument is easy to operate single-handed in addition a powerful 750ml / minute built-in pump will draw a sample from 30m within a few seconds. This alerts the user to a potentially hazardous combustible or toxic gas situation without delay.
