Highly Reliable and User-Friendly Benchtop Meter for Standard Laboratory Applications


Data Transfer

Data transfer and storage are made reliably simple. Standard RS232 and USB interface allows for connection to external devices such as a printer or computer.

Buffers and Solutions 

All kits include 4.01, 7.00, and 10.01 liquid form pH buffers and conductivity standards that do not require reconstitution, allowing for quick, out of the box calibration and set up.

Accurate Electrodes 

All kits include pH probes with temperature sensing and EC probes as well as a standalone electrode holder that provides full flexibility for different types of electrodes.


Capable of measuring up to seven parameters, including pH, ORP, conductivity, TDS, salinity, resistivity, and temperature, with two independent measuring channels which display results simultaneously.

Modern Touch Display 

The 6.5 inch LCD display and touch keypad makes changing parameters, executing setup, and performing calibration as simple as using a smartphone.
