pH 209
Basic pH/mV meter ideal for educational use!
This durable benchtop meter is designed for student use. The front panel features sturdy knobs to manually adjust pH offset and slope in order to demonstrate the calibration concept and the electrode characteristics to students. A 2 point pH calibration is performed manually. Temperature compensation is done manually from 0 to 100°C. The meter is supplied with a refillable combination electrode with a BNC connector.

pH 210/211
Precision pH Meters to simplify routine pH measurements!
These benchtop meters offer one or two point calibration with automatic buffer recognition from your choice of five buffers. Temperature compensation is automatic with the temperature probe included. A stability indicator is displayed when a stable reading is obtained. Model 210 measures pH and temperature. Model 211 measures pH, mV and temperature; it features two mV ranges and can be used in conjunction with ISE and ORP electrodes.

Both meters are supplied complete with a combination glass-body pH electrode, stainless steel temperature probe, electrode holder and calibration buffers.

pH 212/213
High resolution pH meters for more demanding applications!
These research-grade meters offer selectable pH resolution down to 0.001 pH. They feature automatic temperature compensation, one or two point calibration with automatic buffer recognition from your choice of five buffers, and a stability indicator. An RS232 interface allows you to download data to your computer. Model 212 measures pH and temperature. Model 213 measures pH,mV and temperature and can be used with ISE and ORP electrodes in the mV mode.

Both meters are supplied complete with a combination glass-body pH electrode, stainless steel temperature probe, electrode holder, and calibration buffers.
