Measurement principle

Battery-powered zirconia oxygen analyzer

Type

Desktop type / Panel mount type

Display system

4-digit digital display (concentration display)

Measurement range

0-1 / 10 / 100 / 1000 / 10000ppm(1) / 10 / 100vol% O2; 10^-20 to 10^-0atm
Automatic range

Repeatability

Within ±1% of full scale; 1%≦ Sample gas ≦100% Within ±2%of full scale; 10ppm≦ Sample gas <1% Concentrations under 10ppm are not under the warranty range

Sampling system

Continuous suction with internal pump

Sample gas requirements

Pressure: Pressurization at 30KPa or less

Flow rate: 1,000-2,000mL/min

Humidity: Dew point below ambient temperature

Temperature: 0-50ºC

Others: Not to contain corrosive gas (fluorine gas, chlorine gas, sulfuric gas, etc.), gas containing organic silicone, flammable ingredients (including gas), oil or moisture

Reference gas

Atmospheric air

Recorder output

Oxygen level output: 4-20mA; insulated, and load resistance of 550Ω or less
Recorder output range taken as full scale, and oxygen concentration given in linear output
Output range: 0-100% / 0-10% / 10000ppm / 0-100ppm / 0
Automatic/fixed range

Transmission output

RS-232C (Optional)

Alarm output

FAIL (device error): 1 point
Non-voltage contact; contact capacity: 30VDC/AC or less, 0.5A or less
Contact point closes with device error (contact point operation adjustable)
ALM (concentration alarm): 2 points (H/L)
Non-voltage contact; contact capacity: 30VDC/AC or less, 0.5A or less
