P1 & P2 probes are interchangeable when necessary.
122/P1 Narrow Diameter: 5/8 diameter (16 mm) stainless steel. The beam is emitted from within a cone-shaped tip made from rigid polyurethane. The tip is protected by an integral stainless steel shield. This probe is excellent for the vast majority of product monitoring situations.
122/P2 Probe: 1.5 diameter (38.1 mm) stainless steel with Teflon® filled Delrin® tip. The infra-red emitter and detector are protected by glass, which is resistant to all chemicals. Consider this probe for deep applications and in the occasional situation where there is difficulty reading product with the P1 probe.
122M Probe: 5/8 diameter (16 mm) stainless steel. Similar to the P1 but shorter.

Each meter has a grounding clip, a convenient carrying bag with shoulder strap, and a tape guide/datum.
The tape guide may be used to provide support for the reel on the well casing. It acts as a datum allowing repeatably accurate measurements; ensures that the probe hangs in the centre of the well; and protects the tape from damage.

The easy-to-read markings on the tape are permanently heat-stamped into the tape. The dog bone shaped tape avoids adherance to wet surfaces in wells. It is resistant to most chemicals, and the smooth surface of the tape is easy to decontaminate.
The following marking options are available:
M2 & N2 Each 1/100 ft. in black; feet in red.
M3 & N3 Each mm in black; metres in red.
