HM Digital HM-100 Continuous pH/EC/TDS/Temp Monitor

The HM-100 is a pH/EC/TDS/Temp monitor ideal for all water quality testing, hydroponics, water purification applications, wastewater regulation, aquaculture, labs & scientific testing, pools & spas, ecology testing, boilers & cooling towers, water treatment and more.

FEATURES:

• Measures Potential Hydrogen (pH), Electrical Conductivity (EC), Total Dissolved Solids (TDS), Salinity and Temperature
• Four scales: pH, 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
• Data-hold function (Max. 6 data values)
• Large and easy-to-read LCD Screen
• Displays 3 parameters (pH/EC or TDS/Temp) simultaneously.
• Replaceable Sensors (model SP-C2 for Conductivity, SP-P5 for pH)
• Factory Calibrated (pH/EC/TDS)
• Includes power cable, pH 4 & 7 calibration solutions, pH storage solution
