Waterproof Multiparameter PC Testr 35 from Oakton Instruments

Measure pH and conductivity in one easy-to-use meter

  • Combine measurement capabilities of two testers in one convenient pocket-sized unit

  • Up to 5 point pH calibration with NIST or USA autobuffer recognition

  • Conductivty features autoranging based on the concentration of your sample

Great for water, laboratory or plant use, these multiparameter Testrs feature single-junction pH electrodes for longer life and wider 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. Advanced features include auto-shutoff, user-adjustable temperature coefficient and low-battery indicator.
