Ohaus ST20M-C Multi Parameter Pen Meter with Temperature Display

The OHAUS ST20M is a multi parameter pen meter that directly measures pH, conductivity, and temperature, as well as provides conversion measurements for TDS and Salinity.

These fully waterproof pen meters combine measurement capabilities of two testers in one convenient pocket-sized unit.  Great for water, laboratory, or plant use.  The ST20M features a single junction pH electrode and a pin-style conductivity probe for longer usage and durability.

The replaceable electrode module saves you money by reusing the meter body.  Advanced features include auto-shutoff, low battery indicator, as well as simple and easy calibration.
