Waterproof Professional Series Long Probe pH/EC/TDS/Temp Meter Pro Kit

The COM-300L is a professional grade level pH/EC/TDS/Temp meter ideal for all water quality testing, hydroponics, water purification applications, wastewater regulation, aquaculture, colloidal silver, labs & scientific testing, pools & spas, ecology testing, boilers & cooling towers, water treatment and more.

Application: Aquaculture, Aquarium, Drinking Water, Food & Beverage, Hydroponics, Industrial, Pool/Spa, Water Treatment

Measures Potential Hydrogen (pH), Electrical Conductivity (EC), Total Dissolved Solids (TDS), Salinity and Temperature

Five scales: pH, µS, mS, ppm 0.5 (NaCl) Scale & 0.7 (442™) Scale

Automatic Temperature Compensation (ATC) using three temperature coefficients

Digital Calibration (push button) to any point within the meter’s range

Auto-off function, data-hold function and low-battery indicator

Display: large and easy-to-read LCD screen includes simultaneous temperature reading

Includes translucent cap, 2 (AAA) alkaline batteries, pH 4 & 7 calibration solutions, pH storage solution and lanyard

Resolution: 1 µS (0-999); 10 µS (1000-9990); 0.01mS (0-9.99)

Range: 0 – 8560 ppm (0.5 NaCl); 0 – 5000 ppm (0.7 442)

Resolution: 0.1ppm (0-99); 1ppm (100-999); 10ppm (1000-9990)

EC to TDS Conversion Factor: Non-linear conversions for KCl, 442TM or NaCl solutions, selected by the user.

Probe: Detachable platinum electrodes & pH glass sensor with reference tube electrodes

Housing: IP-67 Waterproof (submersible; floats)

Power source: 2 x Triple A (AAA) included
