The HM-100 is a continuous pH/EC/TDS/Temp monitor for growers who want eyes on their nutrient solution around the clock. Mount it on a reservoir and it reads pH, conductivity, dissolved solids and temperature together, so you catch drift before your plants show it. Suited to hydroponics, coco and soil feeds, recirculating systems, aquaculture, boilers and cooling towers.

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
