About this item

These advanced laboratory meters with one or two input channels are ideal for testing critical water quality parameters.

Single- or dual-input channel for pH, ORP, mV, temperature, conductivity, TDS, salinity, DO and ISE: For use with any IntelliCAL™ electrode
Simple user interface that does not require manuals or training to operate
Guided calibration and check standard routines reduce calibration errors while stabilisation alerts
Internal USB ports simplify data transfer, peripherals and software updates, and connection to PCs printer and keyboards
Fully GLP compliant communication and documentation
Ultra-bright screen and large font size for easy to read results

The meters connect with smart probes (IntelliCAL™) that automatically recognise the testing parameter, calibration history, and method settings to minimise errors and set-up time. They are designed to withstand years of continuous lab use.

Ordering information: Supplied with four batteries, universal power adapter, USB cable and electrode holder. IntelliCAL™ electrodes need to be ordered separately.
