Interferometer Type: Type 30MM
Indication Accuracy: ± (Indication Value – AIR CAL Value) x 0.03 ± Drift Amount
AIR CAL Value: Concentration indicated on the display when AIR CAL key is pressed.
Drift Amount: The amount of indication drifting when temperature changes ±10ºC.
Special Caution:
1) This instrument is not explosion proof. This instrument measures combustible gas
around lower explosive limits in this specification. Take enough sample for the
measurement.
2) The measuring range 0-20000 is equivalent to old unit (kcal). Please read it as a
reference value.
3) Calorie amount for pure Propane, pure normal-Butane, and pure iso-Butane for this
instrument is defined and indicated as following the table (Ref. JISK2301-1992-9.)
