The new Handylab range of meters from Schott Glass

The dual pH/LF12 meter measures pH, redox potential, conductivity and temperature, while the Multi 12 meter also features oxygen concentration measurement. Each has a built-in data storage function so that values can be recorded manually or automatically. Other useful features include automatic calibration for conductivity and oxygen concentration, and an optional mains power supply. Fully automated calibration is a major feature of the Handylab pH11 and pH12 meters and makes them ideal for measuring pH (-2.000 to +19.999) and temperature on site.

Conductivity meters LF11 and LF12 measure electrical conductivity, total dissolved solids, salinity and temperature. Both feature a wide cell constant range (0.01/0.090 to 2.500), plus specific resistance or conductivity output modes.

The OX12 is ideal for measuring oxygen concentration (0.00-90.0 mg/l), saturation index (0.0-600%) and temperature in rivers, lakes or water treatment plants. With automatic compensation for ambient temperature and pressure changes (0.0 to 1250 mbar) built in, measurements can be further refined in cases of high salt content. The OX12 is supplied with a current-free at zero galvanic sensor to ensure precise, quick and reliable measurements.

The meters are available alone or complete with case, measuring cell, calibration solution and measuring vessel.
