The HM Digital Pocket-Size TDS Meter is highly effective and accurate due to its advanced microprocessor technology. Small and light, the sleek design offers a hold function, which saves measurements for convenient reading and recording, an auto-off function and LCD screen. With a measurement range of 0 to 9,990 ppm, this meter has a built-in digital thermometer and is calibrated with a 342 ppm NaCl solution. Carries a three-year warranty.
The HM Digital pH HydroTester is a reliable pH meter that is ideal for testing applications such as hydroponics and gardening, pools and spas, aquariums and reef tanks, water ionizers, drinking water and more. The sleek, lightweight design is water-resistant, features one-touch automatic digital calibration, measures temperature, has automatic temperature compensation (ATC) and an LCD screen. This tester includes storage solution in a sponge embedded in a translucent cap, pH 7.0 buffer and batteries. This product carries a one-year warranty.
HM Digital pH Buffer Solution Variety Pack comes with three packets of 4.0 pH, six packets of 7.0 pH and an empty 100 ml bottle. The solution is in powder form, so it's lightweight, takes up very little space, and has an indefinite shelf life.
The conveniently sized HM Digital pH Electrode Storage Solution is made for use with pH meters. For proper care, sensors should always be kept in an electrode storage solution. This specially formulated KCI solution comes with a combination twist-off and eyedropper-style cap for easy application.
The Waterproof EC/TDS/Temp Combo Meter is ideal for all water quality testing, water purification applications, wastewater regulation, aquaculture, hydroponics and more. With four scales, including microsiemens (µS), millisiemen (mS), parts per million (ppm) and parts per trillion (ppt), this meter is a professional-level EC/TDS meter with three different nonlinear EC-to-TDS conversion factors (KCl, 442TM, NaCl) and automatic temperature compensation (ATC) using three temperature coefficients. The meter has measurement ranges of 0-9,990 µS, 0-8,560 ppm, 0-9.99 mS and 0-8.56 ppt; a large and easy-to-read LCD screen with simultaneous temperature reading; replaceable sensor (WCM505) and a one-year warranty. Meter includes a cap, batteries and lanyard.
The HM Digital Waterproof pH Meter is ideal for all pH testing, water purification applications, wastewater regulation, aquaculture, hydroponics and more. This meter has auto-ranging three-point calibration with digital fine-tuning, measures pH and temperature, a measurement range of 0 to 14 pH, a replaceable sensor (WPM505) and features an LCD screen with simultaneous temperature display. This meter includes batteries, a lanyard, pH 7.0 buffer and storage solution in a sponge embedded in a clear cap. This product carries a one-year warranty.
For optimal meter performance, periodically calibrate meters with HM Digital TDS/EC Calibration Solution, or if testing TDS or conductivity levels in wide or different ranges. Made of NaCL solution, this NaCL solution comes in a lightweight HDPE plastic bottle and is sealed with a coated foam liner.
The HM Digital EC/TDS HydroTester is a reliable EC/TDS meter that is ideal for testing applications such as hydroponics and gardening, pools and spas, aquariums and reef tanks, water ionizers, drinking water and more.
