• Oxygen detection element position: fixed to the dedicated holder in the main body case
• Measurement value display: Digital display with 3-digit yellow-green LED
• Measuring range (resolution): 0.0~25.0 (0.1)%O2
• Accuracy rating: +/- 0.5%O2 +/- 1digit in a dry gas of oxygen and nitrogen
• Transmission method: output to 0.0~25.0 measurement indications
• Alarm function: Measured value alarm ...
• Alarm Setting Code: Anoxic Meter Mode
• Lower warning value: 18% fixed
• Upper warning value: fixed at 26%
• Relay power yes/no: yes
• Buzzer with/without: Yes
• Lamp lit/not lit: yes
• Output holding yes/no: yes
• Detection element abnormality alarm: When the heater current to the oxygen detection element is abnormal, relay output is ON, buzzer is blown, and lamp is lit regardless of the content of the measured value alarm.
• Power failure warning: When the power supply to the tester is OFF or when the fuse is broken, relay output is ON.
• Alarm relay output: number of output circuits (2), output capacity (Resistive Load 110 V AC 0.2 A, 24 V DC 1 A/Inductive Load 110 V AC 0.1 A, 24 V DC 0.5 A)
• Warm-up time: 5 minutes
• Note)Alarm signal is OFF during warm-up, transmission signal outputs minimum value
• Operating Temperature Range: 0~40°C
• Operating humidity range: 80%rh or less
• Power: 4.2~5.5 V DC
• When power is supplied from the MG3000 series, use a 2mm2 lead wire within 30 m of each side. Use a 0.75 mm2 lead wire and connect it to a length of 11 m or less per side (wire resistance of 0.3 Ω or less per side). If this length is exceeded, a 100 V AC power supply is required, but use MG1000.
