Description
Description
This portable pump single-gas detector draws air through a built-in micro pump and monitors one selected gas. Fourteen sensor configurations cover combustible gas, oxygen and a range of toxic gases. Choose the gas configuration and measuring range for the monitoring task.
The color LCD shows the gas name, concentration, unit, time, alarm status and battery level. Audible, visual and vibration alarms provide alerts, while magnetic charging, a large back clip and a top flashlight support portable use.
Pump Sampling and Gas Selection
The internal micro pump has ten selectable suction levels. Each order supplies an instrument configured with one selected gas sensor. The gas selector identifies the sensor supplied with that instrument.
Use the gas-specific measuring range, minimum reading and response value when comparing configurations. For remote sampling, select the tubing, filters and connections for the target gas and the instrument's operating procedure.
