Thermo Scientific Alpha pH 500

pH/ORP 2-Wire Transmitter

Thermo Scientific Alpha pH 500Product Features

Clear, uninterrupted data transmission is no problem with the Alpha pH 500, even in environments with electrical interferences. User-friendly and cost efficient, the transmitter comes with a large LCD screen to double up as a monitor – very convenient for quick checks on-the-spot.

:: Measures, displays and transmit pH/ORP with temperature simultaneously

:: Symmetrical Mode option, two-wire design and input-to-output isolation give clear, uninterrupted data transmission in electrically noisy ambient   

:: High quality, high resolution output at chart printers and other secondary devices  

:: Offset Adjustment Function allows you to adjust readings conveniently without having to remove electrode from the measurement tank or pipe  

:: Reliable, accurate measurements at different temperature with Automatic Temperature Compensation
