Ohaus Starter Water Analysis Pen Meters

The OHAUS Starter Water Analysis Pen Meters are a line of pen meters that are durable, practical, and affordable. Starter Pen Meters are the portable solution for on-the-go measurement of pH, ORP, conductivity, salinity, and TDS. Each model is constructed with durable plastic housing, a protective cap that safeguards the sensor, and an automatic shutdown feature to preserve battery life. They are equipped with a wrist strap that helps prevent accidental dropping, although they are constructed with an IP67 waterproof design that can prevent water damage if dropped into liquid.

pH Meters- offer a convenient way to measure pH, or the relative acidity or alkalinity of a sample at a given temperature. the pH meters can be completed operated with just one hand, freeing up your other hand to handle samples

ORP Meters- can bring measurement of ORP virtually anywhere the need exists. They provide almost instantaneous results and OHS30073985 offers the ability to hold the reading right on the display to provide additional time for data logging.

Conductivity Meters- with six models that measure withing 3 different conductivity ranges, there is a meter for every application that requires portable operation and quick results

Salinity Meters- combine all the most useful features for measuring salinity in a liquid medium. Choose from 2 models with ranges up to 10.0 ppt (OHS30073982) or 80.0 ppt (OHS30073983).

TDS Meters- Bring the Starter TDS Meter wherever you need to measure the combined content of all organic and inorganic substances in a liquid. There are 4 models to choose from each with a unique range and display options.
