Portable and Digital Meters

Model 107 pH Meter- This meter is a rugged reliable instrument featuring complete portability. It is an analog based unit with range 2-12 pH, battery operated. It is provided complete with 30-inch handheld probe and start-up buffer solutions. Note: The leather carrying case is no longer available.

Model 707 pH Meter- This meter is our most popular portable meter and is pictured above. It is an analog unit and can be provided as 115 volt AC or battery operated. The meter features a big 7-inch scale of 0-14 pH and is a rugged, reliable instrument. Simple to operate with only two operating controls and is provided complete with 30-inch handheld probe and start-up buffers.

Model 707 Redox/pH Meter- This meter (pictured above) is the same as the Model 707 pH meter except it combines pH and Redox (ORP) readings with 0-14 pH and -700/0/+700 millivolts. It is a versitile portable instrument capable of measuring either pH or ORP via a selector switch. Separate probes are required for measuring the pH or ORP. The meter is currently available only as battery operated, and is complete with 30-inch handheld probes and start-up buffer solutions.

Model 721 Digital Benchtop pH Meter- This meter is a benchtop meter with digital display, range 0-14 pH, 115 volt AC. It is provided complete with 30-inch handheld probe and start-up buffer solutions. This meter can be also ordered as a combination pH and ORP capable of measuring either pH or millivolts via a selector switch and separate probes.

Model D-1, Single Digital pH Meter- This unit is a compact digital pH meter mounted in a Nema 4X enclosure suitable for wall mounting in wet processing areas. It contains a single digital display with range 0-14 pH, 115 volt AC. Provided complete with probe and buffer solutions. This unit can also be coupled with either a separate circular chart recorder or strip chart recorder if a permanent record is required.

This meter can also be provided as an ORP indicator with range +/- 1,999 mV utilizing a platinum tipped ORP probe.

Model DD-2, Dual Digital pH/ORP Meter- This unit is similar to the D-1 except it contains two (2) digital displays in the same Nema 4X enclosure. Any combination of pH and/or ORP can be selected with measuring ranges of 0-14 pH or +/- 1,999 millivolts for ORP. The unit contains two separate independent meters requiring two probes of either pH or ORP dependent on selection of measurements. Available Option includes a 4-20 mA output. This unit can also be coupled to a separate circular chart or strip chart if a permanent record is required.
