Fast & Reliable
Suitable for many applications, this gas detector is ideal for confined spaces and safety monitoring with its Normal Operating mode and leak investigations with its Leak Check mode. Controlled by a microprocessor, this gas detector continuously checks itself for sensor connections, low battery, circuit trouble, low flow, and calibration errors. In addition, this detector features a large LCD that shows all gas readings, battery level, and current time and automatically backlights in alarm conditions.
Features
Buzzer
One solid-state electronic buzzer is located inside the case. Sound exits the case through a hole in the middle front of the case. The buzzer sounds for gas alarms, malfunctions, low battery voltage, and as an indicator during use of the multi-gas detectors many display and adjustment options.
Charging indicator LED
One LED located near the bottom of the instrument lights up green when a power cable is plugged into the instrument's charging/data port. The LED changes to orange as charging begins. When charging is complete, the LED turns green until the instrument is disconnected from power.
Case
This multi-gas detectors sturdy, high-impact plastic case is radio frequency (RF) resistant and suitable for use in many environmental conditions, indoors and out. The case is dust-proof and waterresistant. A clear plastic window on the front of the case allows for LCD viewing.
Flashlight LED
A white LED is visible through a round, raised, frosted lens in the top of the case. This LED can be used to provide extra light, if necessary. The flashlight can be activated in the Display Mode.
Flow chamber
The flow chamber is on the back of this multi-gas detector and is held in place by four Phillips screws. The flow chamber seals to the rubber sensor gasket which seals to the sensor faces inside this multi-gas detector and routes flow from the pump to the sensors and to the exhaust port (on the back of this multi-gas detector's case).
Sensors
This multi-gas detector uses three sensors to monitor combustible gas, oxygen (O2), carbon monoxide (CO), and hydrogen sulfide (H2S) simultaneously. The sensors are located inside this multi-gas detector and are held in their sockets by the sensor retainer and back case. The sensors use different detection principles, described in the following sections.
Combustible gas sensor
The combustible gas sensor (NCR-6309) detects combustible gas in the %LEL range using 2 catalytic elements: A standard element and a poison-resistant element that is resistant to sensor poisons like silicone. The element's electrical resistance changes based on the reaction of gas with oxygen. The change in resistance affects the current flowing through the element. This multi-gas detector's circuitry amplifies the current, converts the current to a gas concentration, and displays the concentration on the LCD. The standard calibration for the combustible gas sensor is to methane, but the sensor will still detect and respond to a variety of combustible gases.
AIR mode
POWER mode
O2/CO/H2S Sensors
The O2, CO, and H2S sensors are electrochemical cells that consist of two precious metal electrodes in a dilute acid electrolyte. A gas permeable membrane covers the sensor face and allows gas to diffuse into the electrolyte. The gas reacts in the sensor and produces a current proportional to the concentration of the target gas. This multi-gas detector's circuitry amplifies the current, converts the current to a gas concentration, and displays the concentration on the LCD.
Inlet filter holder
The filter holder is a clear plastic dome-shaped piece on the top of the case. A male quick connect fitting is located on the inlet filter holder. This is the multi-gas detector's inlet fitting. The filter holder may be removed by turning it counterclockwise and pulling it away from the case. One flat membrane disk hydrophobic filter, a wire mesh disk, and a rubber filter retaining gasket are held in place by the filter holder and are located in the bottom of the case chamber where the filter holder is installed.
USB type-C data/charging port and protective cover
A USB type-C port is located on the bottom of this multi-gas detector, protected by a rubber cover. Pry off this cover when plugging in a USB Type-C cable (for charging or data transfer). A USB Type-C adapter cable can be connected to a computer's USB port to transfer data to this multi-gas detector's Data Logger Management Program.
Battery pack
A lithium ion (Li-ion) battery pack powers this multi-gas detector. At 77°F (25°C), the battery lasts at least 30 hours. The battery icon in the lower left corner of the LCD shows remaining battery life. A low battery warning activates when this multi-gas detector detects a low battery voltage. This multi-gas detector sounds a dead battery alarm when battery voltage is too low for Measuring Mode. The battery pack can be recharged using an AC or DC charger. Use of batteries or battery chargers not specified by RKI Instruments, Inc. will compromise the CSA classification and may void the warranty. (Warning: To prevent ignition of a hazardous atmosphere, batteries must only be charged in an area known to be nonhazardous)
