A test device for testing an oxidation potential of an electrolyte is provided. The test device comprises a cavity, a test unit, a detector, a processing unit, and a display. The test unit comprises a positive plate comprising a first through hole, a negative plate comprising a second through hole, a first infrared window covering the first through hole, a second infrared window covering the second through hole, and an electrolyte located between the positive electrode plate and the negative electrode plate. The first through hole and the second through hole penetrate each other. The first infrared window, the positive plate, the negative plate, and the second infrared window are stacked with each other. An infrared light beam passes through the first infrared window, the first through hole, the electrolyte, the second through hole, and the second infrared window in sequence and then is detected by the detector.

A remote sampling sensor for determining characteristics of a sample includes measurement optics and an insertion probe. The measurement optics are configured to emit light and detect returned light. The insertion probe includes a chamber, the chamber being configured to permit the sample to enter the chamber, an insertion tip at a distal end of the insertion probe, and a retro-reflective optic adjacent the insertion tip. The retro-reflective optic is configured to return the light from the measurement optics through the chamber to the measurement optics. The insertion probe is configured to be remotely located from the measurement optics.
