Physical Dimensions:

Vial Length: 1.23” (31.2mm)
Vial Diameter: 0.36” (9.1mm)
Lead Length: 6.0” (152.4mm)

Sensor Test Circuitry: Tests involve exciting the electrodes with a 400 Hz AC signal to produce maximum current at null. Output readings are taken between the center electrode and the center of balanced resistors R1 and R2. Tests are conducted at +25°C.

Important Note: Ensure all test and operating circuits are free of direct current to prevent damage and instability.
