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.
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 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.
The Industrial Dual TDS Monitor is designed for commercial and industrial applications, and measures the amount of tap water coming into a water filtration system then compares it to the amount of purified water going out by using in and out electrode probes. The monitor is highly efficient and accurate because of its microprocessor technology, and has a dual range of 0-9990 pp with an accuracy of ±2%. All monitors are factory calibrated with a 342 ppm NaCl solution, and can be calibrated individually or simultaneously. Other features include an auto-off function to conserve battery power, large and easy-to-read LCD display, a battery life of approximately 12 to 18 months (two AA batteries included), ¼” standard fittings, a strong and water resistant casing and cable, and a 46” cable length. The monitor measures 4.6”x2.6”x.7” and installs quickly and easily with the Mur-lok® Quick-Connect T-fittings.
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. With four scales, including microsiemens (µS), millisiemens (mS), parts per million (ppm) and parts per trillion (ppt), this water-resistant tester is excellent for nutrient testing, and the LCD screen displays simultaneous temperature reading. Measurements range from 0 to 9,990 µS, 0 to 5,000 ppm, 0 to 9.9 mS and 0 to 5.0 ppt. This product includes a protective cap and batteries and carries a one-year warranty.
The HM Digital HydroMaster HM-500 monitors pH, electrical conductivity (EC), total dissolved solids (TDS) and temperature with very high accuracy. This instrument can be calibrated with various buffer solutions, and is equipped with automatic buffer recognition for user convenience. The touch-screen LCD makes it user friendly and features automatic light detection making it easy to view in dark environments. Includes a wall-mount bracket, EC/TDS/temp sensor, pH probe, USB power adapter and cable, two sensor holding clips, one packet each of liquid PH-STOR, PH-4, PH-7 and C-1000 ppm, and an extensive user's guide.
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 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.
