PH, EC, TDS and temperature meter, low range

Features of the Combo Waterproof pH/EC/TDS/temperature meter - low range:

The Combo series waterproof pocket instruments, offer high accuracy pH, EC (conductivity) /TDS (dissolved solids in water) and temperature measurements. It is no longer necessary to use 2 or 3 instruments for such measurements: in fact, these testers display on the screen, the pH or EC/TDS readings automatically compensated in temperature and the temperature value of the sample in degrees Celsius. For more accurate results in each application, the EC/TDS conversion factor can be selected by the user, as well as the temperature compensation coefficient (ß). It is possible to program the ß (Beta) coefficient between 0.0 and 2.4 % per °C, in 0.1 increments.

These meters are waterproof and floatable, and feature a large 2-level display: displays pH/CE/TDS simultaneously. They have automatic shut-off in case of inactivity.

The pH electrode can be easily replaced and has a long life due to the renewable fibre junction. The stainless steel connector of the pH electrode is robust and can be inserted without any difficulty. The pH calibration is automatic with 2 sets of stored buffers: standard 4.01/7.01/10.01 pH or N.I.S.T 4.01/6.86/9.18 pH

(N.I.S.T: National Institute of Standards and Technology)

The graphite EC/TDS probe is not damaged by salts and other aggressive substances and therefore ensures more accurate measurements. For total dissolved solids (TDS) measurements, the conversion factor can be programmed between 0.45 and 1.00 in 0.01 increments.

The fully exposed stainless steel temperature sensor reduces instrument response times; its proximity to the pH/EC/TDS probes increases the accuracy of automatically compensated measurements.
