Consolidating five essential water chemistry metrics into a single handheld instrument, this compact tester tracks pH levels, total dissolved solids, electrical conductivity, oxidation-reduction potential, and liquid temperature. Designed for horticulturists, researchers, and household users, it streamlines routine analysis for indoor gardens, greenhouse operations, swimming features, aquarium setups, and potable water verification.
Build and Usability
Crafted for practicality in wet or humid workspaces, the unit carries an IP67 waterproof rating that protects internal components from splashes and brief submersion. Its streamlined, ergonomic housing allows for comfortable one-handed operation during extended testing sessions. To maintain reading stability across varying climates, the device applies automatic temperature adjustment between 0 °C and 50 °C. Power management features include a built-in timer that powers down the display after five minutes of inactivity, extending cell life. Three AG-13 batteries (1.5 V each) are required for operation but packed separately.
Technical Readings
- Electrical Conductivity: 1 to 19990 µS/cm range, resolving at 1 µS/cm with ±2% full-scale accuracy.
- Total Dissolved Solids: 1 to 19990 ppm measurement window, stepping in 1 ppm or 0.1 ppt increments at ±2% tolerance, utilizing a standard conversion coefficient of 0.5.
- pH Scale: 0.01 to 14.00 coverage, delivering 0.01 resolution and ±0.05 precision.
- Oxidation-Reduction Potential: ±1000 mV detection band, calculating in 1 mV steps with ±2 mV accuracy.
- Thermal Monitoring: 0.1 to 60.0 °C (32–140 °F) capacity, offering 0.1 °C accuracy alongside a noted resolution of ±1.0 °C.
Operational environments accommodate temperatures from 0 °C to 60 °C under up to 100% relative humidity, ensuring steady functionality across diverse locations. By unifying nutrient assessment, salinity checks, and thermal verification into one resilient instrument, this meter provides dependable data for maintaining optimal hydration standards in any controlled environment.
