Yokogawa Conductivity Sensor SC4AJ
For a cell constant: 0.02cm-1
In case of the combination with the SC450G, FLXA21,SC202G or SC202SJ:
0 - 0.5 S/cm to 0 - 200 S/cm
In case of the combination with the SC100:
0 - 100 S/cm to 0 - 1 mS/cm
(Material: Titanium only, SC100 can not use with SC4AJ sensor made of SUS which cell constant is 0.02 cm-1.)
For a cell constant: 0.1cm-1
In case of the combination with the SC450G
, FLXA21,SC202G or SC202SJ:
0 - 5 S/cm to 1 mS/cm
In case of the combination with the SC100:
0 - 500 S/cm to 0 - 5 mS/cm
(Material: Titanium)
In case of the combination with the SC100:
0 - 500 S/cm to 1 mS/cm (Material: SUS) Temperature Range: For electrode, 0 to 110 C
Sterilization for electrode:135 C (275 F), within 30 minutes in Steam Sterilization
Pressure range : For electrode, 0 to 1 MPa
Sample solution condition:
Although flow rate is not limited in measurement, air bubbles should not be mixed in the sample solutions to obtain correct measured values.
Temperature sensor: Pt1000

Weight:
Sensors:
Adapter mounting type
(SC4AJ-S-AD-09-002-05): approx.450 g
Adapter mounting type
(SC4AJ-S-AD-15-002-05): approx.520 g
Welding socket type
(SC4AJ-S-SA-NN-002-05): approx.670 g
1 or 1.5 inch welding clamp type
(SC4AJ-S-SB-NN-002-05): approx.550 g
2 inch welding clamp type

(Note) There are weightdifferences amongSC4AJ sensors. In orderto know the more accurateweight of each type of sensors,please calculate it from following information. The cable weighs 75 g/m. The SC4AJ with 0.02cm-1 cell constant is 15 gram heavier than the SC4AJwith 0.1cm-1 cell constant. SUS314L electrodeis 40 g heavier than Titanium electrode.
Adapters:

3/4NPT stainless steel adapter (/PS):a pprox. 110 g
R3/4 stainless steel adapter (/RS): approx. 110 g
3/4NPT PVDF adapter (/PF) : approx. 35 g
R3/4 PVDF adapter (/RF) : approx. 35 g
Straight welding socket (/SA1): approx. 300 g
Angle welding socket 15 (/SA2) : approx. 320 g
Welding clamp 1 inch (/SB1) : approx. 330 g
Welding clamp 1.5 inch (/SB2) : approx. 305 g
Welding clamp 2 inch (/SC1) : approx. 350 g
(Note) Do not submerge the sensor itselfin process water, as the seams between the mold and the metalof the sensor are not waterproof.
