Measuring
items		 1)Gas volume / internal gas pressure of carbonated drink
2)Gas volume / internal gas pressure of carbonated drink,air content and oxygen concentration
3)Inside gas pressure of non-carbonated drink
Measuring
range
Pressure ： 55 to 10cmHg and 9.8kPa to 0.490MPa
（0.1 to 5.0kgf/cm2G）
Temperature ： 0 to 50℃
Residual gas
volume		 ： 0 to 30mL(Residual gas volume after the absorption of alkaline aqueous solution)
Oxygen
concentration		 ： 0 to 21%(Oxygen concentration measurement is not available when the residual gas volume is 8mL or less.)
Measurement
accuracy
Pressure ： +/- 0.001MPa（+/- 0.01kgf/cm2G）
Temperature ： +/- 0.05℃
Residual
gas volume		 ： +/- 2% (for 5mL or over and 30mL or less)
for the measured value
+/- 0.1ｍL (for 0mL or over and 5mL or less) for the measured value
Oxygen
concentration		 ： +/- 0.2%
Calibration
Gas volume
measuring unit		 ：
Pressure sensor-zero : pressure gauge for calibration 0.000MPa(0.00kgf/cm2G)
Pressure sensor-span : pressure gauge for calibration 0.490MPa (5.00Kgf/cm2G)
Temperature sensor : standard thermometer, pure water

measuring unit		 ： Pressure sensor-zero : pressure gauge for calibration 0.000MPa(0.00kgf/cm2G)
Pressure sensor-span : pressure gauge for calibration 0.098MPa (1.00Kgf/cm2G)
Oxygen
measuring unit		 ： Oxygen sensor : automatic calibration during pretreatment (manual calibration is possible)
Temperature sensor : room temperature
Measurement
time
For measuring gas volume / internal gas pressure only : approximately 90 seconds for one sample
For measuring gas volume, air content and oxygen concentration : 6 to 16 minutes for one sample
Note: Measuring time varies according to sample and condition
Sample container PET bottles : 2.0L or smaller (190mL cans, various PET containers)
Maximum container : 110 (φ) x 320 (H) mm
Display 16-digit and 1-row LCD (with backlight)
Number of main unit stored data Measurement conditions are storable to the main unit up to 20 sets
Measurement data as many as the latest 100 samples are storable
By using a USB flash drive, can be taken out in a CSV format
Calculation
Gas
volume		 ： Calculation of gas volume / internal gas pressure by using the balance pressure inside the sample container and sample temperature.
Calculation formula for the soft drink standard(*1) or the EBC standard (*2) can be selected.

*1 According to “Chart 13-2 Table of absorption coefficients of carbon dioxide” in revised Soft drinks overseen by Japan Soft Drink Association
*2 According to ASBC Methods of Analysis -Beer-13: Dissolved Carbon Dioxide
Air
Content		 ： Calculation of air content by using the residual gas volume and oxygen concentration after absorbing carbon dioxide in the alkaline aqueous solution
External
