NOTE
The alarm accuracy and alarm delay time on the specification are applied to the calibration gas (CH4 or
HC) only.
The concentration displayed for a converted reading is a reference value. To display an accurate
concentration, gas calibration using the gas to be measured is required. Therefore, request RIKEN
KEIKI for calibration using the gas to be measured.
See the following table "GP-1000 Gas List" for a list of gases available for reading.
The gas detector provides two different specifications for target combustible gases: "general
combustible gases (HC)" and "methane (CH4)". Some gases cannot be read depending on the
specification. See the following table "GP-1000 Gas List".
