Measuring pH, conductivity, total dissolved solids and temperature in one slim lightweight casing and with one single probe - the HI-991300 is an ideal portable pH tester.
There are only 2 buttons, yet you can select from a range of calibration buffers and even the temperature scale most familiar to you. The housing is waterproof and rated for IP 67 conditions.
The HI-1288 pre-amplified multiparameter probe features an easy to clean sensor and a cloth junction that can be pulled longer to increase the life of the probe.
