Spec

• Transmission signal output: 0~250 mV
• alarm setting
• Densitometer Mode Type II (fixed by user)
• Lower limit value, Upper limit value, buzzer enabled/disabled, lamp enabled/disabled, relay output enabled/disabled, output holding enabled/disabled
• Unspecified parameters are the default values for densitometer mode Type I.
• Display range: 0.0~25.0%O2/0.00~2.50%O2 Automatic switching
• Transmission output range: output corresponding to 0.0~25.0%O2
• *Possible combinations of display range and transmission output range are 00, 11, 20, and 22. However, only 00 can be specified when the alarm setting is the oxygen deficiency meter mode.
• For densitometer mode Type I and display range 1: Alarm initial value is lower limit 0.00%, upper limit 2.50%
• Measurement Principle: Zirconia Solid Electrolyte Method
• Air sampling method: natural diffusion type
• Response time: 90% response within 20 seconds
• 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
• Measurement Range (Resolution): 0.00~2.50 (0.01)/2.0~25.0 (0.1)%O2 (Automatic Range Switching)
• accuracy rating
• For 0.0~25.0%O2 ...±0.5%O2±1digit
• For 0.00~2.50%O2 ... +/- 0.05%O2 +/- 1digit (in a dry gas of oxygen and nitrogen)
• Transmission method: 0~100% of the output signal is output to 0.00~2.50, and 8~100% of the output signal is output to 2.0~25.0
• Alarm function: Measured value alarm ...
• Alarm setting code: Densitometer mode *1
• *1 Alarm setting "A" is set to the initial value at the time of shipment, and alarm setting "B" is set to the state of alarm setting "0" for unspecified alarm value and alarm output operation.
• Lower warning value: specified within 0~26% *2
• Upper warning value: specified within 0~26% *2
• *2 The lower alarm value cannot be set to a value larger than the upper alarm value or cannot be specified. When alarm release alarm is held, it is released by front reset key.
• Relay output yes/no: Optional
• Buzzer with/without: Optional
• Lamp ON/OFF: Optional setting
• Output Hold Yes/No: Optional
• 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.
