Great for water, wastewater, laboratory or plant use, these multiparameter testers feature long-life pH electrodes with a wide range of sample compatibility. Pin-style conductivity sensors feature stainless steel electrodes for chemical resistance and durability. Replaceable sensor module saves you money by reusing the meter body.

The testers bring the performance of your lab instruments out into the field. Advanced features include: auto-shutoff, user-adjustable temperature, coefficient self-adjusting TDS and salinity factor, and low-battery indicator.



  • Combine measurement capabilities of three testers in one convenient pocket-sized unit
  • Up to 3 point pH calibration with NIST or USA auto buffer recognition
  • Conductivity, TDS, and salinity feature auto ranging based on the concentration of your sample
  • Redesigned leakproof cap functions as a sample/calibration cup, hydrating cup, and stabilizing base to stand the meter upright
