HM Digital COM-100: Waterproof EC/TDS/Temp Combo Meter

UPGRADED!(See below)† Ideal for all water purification applications,wastewater regulation, aquaculture, hydroponics, colloidal silver, labs& scientific testing, pools & spas, ecology testing,boilers& cooling towers, water treatment & more.

Features
- Measures electrical conductivity (EC),total dissolved solids (TDS) and temperature
- Upgraded:Four scales: µs, mS, ppm, ppt (mS and ppt are new)
- Three different non-linear EC-to-TDS conversion factors (KCl. 442^TM,NaCl)
- Automatic Temperature Compensation (ATC) using three temperaturecoefficients
- Waterproof housing (IP-67 rating)
- Measurement Range:0-9990 µs; 0-8560 ppm; 0-9.99 mS; 0-8.56 ppt
- Digital Calibration (push button) to any point within th meter's range
- Replaceable Sensor (model SP-C1)
- Auto-off function, data-hold function and low-battery indicator
- Display:large and easy to read LCD screen includes simultaneous temperaturereading
- Factory Calibrated:The COM-100 meter is calibrated with a 1413 µs solution. The meter canbe recalibrated with digital calibration using the push buttons, ratherthan a screwdriver
- Includes cap, batteries and lanyard
