Yokogawa 2-Wire Analyzer FLXA21-D-E-D-AA-C1-NN-A-N-LA-N-NN/U/SCT
The FLXA21 two-wire liquid analyzer offers single or dual sensor measurement. The modular-designed analyzer offers 4 kinds of measurements – pH/ORP (oxidation-reduction potential), contacting conductivity (SC), inductive conductivity (ISC) or dissolved oxygen (DO) – with the respective sensor module.
The FLXA21 Conductivity Analyzer with temperature compensation function and built-in standard calibration table can monitor the contamination of cells and measure the electrical conductivity with higher precision. It has high versatility with the cell constant in the range of 0.005 to 50 cm-1, and both the 2-electrode and 4-electrode sensors can be used. In addition, 5 types of temperature sensors can be used to ensure accurate temperature compensation can be performed.
The Yokogawa 2-Wire Analyzer FLXA21-D-E-D-AA-C1-NN-A-N-LA-N-NN/U/SCT offers ultrapure water compensation for demineralized water, steam, condensate and boiler water analysis. As for the ultrapure water monitoring in the pharmaceutical industry, the Yokogawa 2-Wire Analyzer FLXA21-D-E-D-AA-C1-NN-A-N-LA-N-NN/U/SCT can monitor the water quality of process liquid according to the water quality standards to meet the USP (United States Pharmacopoeia) Chapter <645> (see Chapter 645 in the USP 23).
For the wide range of industrial environment, the FLXA21 pH/ORP Analyzer is designed with the enclosure of plastic, stainless steel or stainless steel with corrosion resistant coating.

Notes:
1: When a 2nd input is selected, only the same kind of the 1st input is available.
For example, when a 1st input is “-P1”, the 2nd input must be the same “-P1”.
The combination of ISC and ISC is not available.And, the combination of SENCOM sensor and SENCOM sensor is not available, either.
2: These languagesare message languages on the analyzer’s display.
One Yokogawa 2-Wire Analyzer FLXA21-D-E-D-AA-C1-NN-A-N-LA-N-NN/U/SCT has English and 11 languages.
All languages are as follows;English, Chinese, Czech, French, German, Italian, Japanese, Korean, Polish, Portuguese, Russian and Spanish.
3: When an analyzeris used in Japan, it must meet the Japanese Measurement Law.
Only SI units must be used on the analyzerand its documents in Japan.
4: The universalmounting kit contains the pipe and wall mounting hardware (/U) and the panel mounting hardware (/PM).
5: The type “-EA” is intrinsically safe type of ATEX, IECEx, FM, CSA and NEPSI, and non-incendive of FM and CSA.
6: The analyzer with Japanese Measurement Law certificate is available only for the following model; FLXA21-D-[Housing code]-D-AA-P1-NN-A-N-LA-J-NN/[option code except /K]/K
Only one pH measurement with an analog sensor is certified. The output signal of 4 - 20 mA is certified. HART communication is not certified.
7: This input is to be come from an analog pH/ORP sensor.
8: When the analyzer is connected with the digital sensor, FU20F pH/ORP SENCOM Sensor, only the following model is available;
Type: General purpose (-AA)
2nd input: Withoutinput (-NN) Option: except “/K”
