HM Digital Com-300 Ph/Tds/EC/Temp Meter

The new waterproof professional COM-300L pH/EC/TDS/Temperature Meter is the ideal solution for all water quality assessment needs. Its extended design allows all parameters to be measured in large tanks or drums. The built-in Automatic Temperature Compensation (ATC) sensor ensures accurate temperature measurements. FEATURES: - Measurement of hydrogen potential (pH), electrical conductivity (EC), total dissolved solids (TDS), salinity and temperature - Five scales: pH, µS, mS, ppm 0.5 (NaCl) Scale and 0.7 (442™) Scale - Automatic Temperature Compensation (ATC) using three temperature coefficients - Waterproof housing with protection class IP-67 - Digital calibration (button) to any point within the range of the device - Auto power off, data hold, and low battery indicator function - Large and easy-to-read LCD with simultaneous temperature display - Replaceable sensor (model SP-C3) - Factory calibration (pH/EC/TDS) - Includes: transparent lid, 2 AAA batteries, pH 4 and 7 calibration solutions, pH solution storage and lanyard SPECIFICATION: - pH range: 0 – 14 - EC range: 0 – 9990 µS; 0 – 9.99 mS - TDS range: 0 – 8560 ppm (0.7 Scale); 0 – 5000 ppm (0.5 Scale) - Temperature range: 0-55 °C; 32-130°F - Resolution: 0-99: 0.1 µS/ppm/ 0.01mS; 100-999: 1 µS/ppm; 1000-9990: 10 µS/ppm.
