Multiparameter water quality pens in four models, each with a replaceable probe: LPHT1-Plus (pH, ORP and temperature), LPORPT1-Plus (ORP and temperature), LPECT1-Plus (conductivity, TDS, resistivity, salinity and temperature) and LPCT1-Plus (all parameters combined). Automatic temperature compensation over 0-60 C; powered by 4x AAA batteries. Each kit includes the meter, probe, calibration standards, hard case and lanyard. Replacement sensors are listed separately as the LPHT1-Plus Spare Sensors product. Per-model specifications are listed in the comparison table below.
