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) This instrument measures extremely toxic gases. It exhausts sample gas from GAS
OUT, and sample gas may leak from internal piping. Take enough sample for the
measurement.
