Description
You can measure pH, electrical conductivity (EC), total dissolved solids (TDS) and temperature in a single, slim, lightweight, portable instrument. It is waterproof with many advanced features.
Features:
- Measures four parameters- pH, electro-conductivity (EC), total dissolved solids (TDS) and temperature.
- Two buttons allow selection from a range of calibration buffers and the temperature scale (°C or °F) as desired
- Standard buffer recognition values
- Automatic one or wo point calibration
- Multi-level LCD display; the meter displays the current measurement simultaneously with the current temperature and calibration guides
- The housing is waterproof and rated for IP 67 conditions
- On-screen tutorial messages for calibration and setup
- HOLD: the HOLD button freezes readings on the display for manual recording
- Automatic temperature compensation
- BEPS (Battery Error Prevention System) alerts the user in the event that low battery power could adversely affect readings
- Battery % displayed on startup
- The pre-amplified, multi-parameter probe, includes pH, EC/TDS and temperature in one convenient, rugged handle
- Probe's extendable cloth junction extends its usefulness
- Includes different TDS factors from 0.45 to 1.00, and a range of temperature coefficients (ß) from 0.0 to 2.4%. Also selectables are standardized buffer recognition values
- To ensure against interference from transient electrical noise, a solid-state amplifier is integrated into the probe
- Easy to clean and keep clean
- Convenient—palm-sized unit and bottom probe connection that keeps the cable out of the way
