Attention Micro ORP probe 5 Copyright © Atlas Scientific LLC Atlas Scientific Reference Probe This is a half-cell ORP probe. It MUST be connected to a reference probe before it will work.
No readings Unpredictable results Atlas Scientific Reference Probe Atlas Scientific Reference Probe Reference Probe Atlas Scientific Correct In order to take accurate readings, both ORP and Reference micro probes must be placed within the same sample of liquid. Atlas Scientific Reference Probe 6 Copyright © Atlas Scientific LLC Half-cell SMA breakout boards create a single output, just like a normal probe.
Half-cell operating principle Back in the day, ORP probes would come with a separate reference probe, which is crucial for accurate readings. Modern day ORP probes have the reference built in, creating an all in one package. In order for Atlas Scientific to get the size of our Micro ORP probe down to 6.2mm, we had to separate the reference into its own micro probe. Both ORP and reference micro probes are needed in order to take accurate readings.
Unique behavior Atlas Scientific’s microprobe technology has some unusual properties. Unaffected by drying ORP probes need to be kept wet at all times. If an ORP probe is allowed to dry out, the probe could be permanently damaged. Atlas Scientific’s micro probes seem to be unaffected by drying. We have found that if a micro ORP or micro reference probe is allowed to dry, the probe still works normally when it's put back into water.

An ORP probe is a passive device that detects a current generated from the oxidation or reduction chemical substances in water. This current (which can be positive or negative) is very weak and cannot be detected with a multimeter, or an analog to digital converter. 0 0 0 0 V V Improve response time Vigorously stir the probe in the sample, calibration solution, or rinse solution. This action will bring solution to the probes surface quicker and improve the speed of response.

Probe cleaning Coating of the ORP bulb can lead to erroneous readings including shortened span. The type of coating will determine the cleaning technique. Soft coatings can be removed by vigorous stirring or by the use of a squirt bottle. Organic chemical, or hard coatings, should be chemically removed. A light bleach solution or even a 5 – 10% hydrochloric acid (HCl) soak for a few minutes, often removes many coatings. Do not use abrasive materials on the ORP probe.
