Wireless Signal Output (Note 2) Yes
Data Storage to External Media (Note 2) Allows data in CSV format to be saved to a USB flash drive
Permitted Ambient Temperature 5 to 40°C. Should be protected from direct sunlight and radiant heat.
Power Requirements 110 V, 115 V, 120 V, 127 V, 220 V, 230 V, 240 V AC, 50-60 Hz, max. 150 VA
Dimensions W260 × H452 × D420 mm (Excluding protrusions)
Weight (Main unit) Approx. 16 kg
External drain separator Yes No
Sample Gas Conditions (Note 3) At the CGT-7100 main unit inlet
Pressure: -980 to +980 Pa
Temperature: Ambient temperature
Dust: 0.1 g/Nm3 max.
Composition: N2: 70 vol% min.; SO3: Not contained; H2O: Below the saturation point at ambient temperature
External Signal Input 0-1 V DC, 1 channel, signal input from an external analyzer, display

Note 1: Response time is measured from the point the gas enters the sample gas inlet until 90% response is indicated (flow line purge time plus electrical system response time).
Note 2: Available smart devices and USB flash drives are posted on the Shimadzu Corporation website.
Note 3: If conditions are not satisfied, contact a Shimadzu representative. If a mist absorber set (option) is used, then an SO3 mist can be used up to about 30 ppm.
             If the concentration of a component other than N2 is 30 vol% or more, then measurement specifications might not be satisfied in some cases.
Note 4: Please contact us if you would like other combinations of measurement components or measurement ranges.
Note 5: Please contact us if you wish to measure O2 concentration.
