Hanna Instruments GroChek pH/EC/TDS/Temp. Combo (HI991404)

This indicator continuously monitors the three most crucial nutrient parameters in hydroponic, greenhouse, and horticultural applications.

This instrument is supplied with a non-clogging double junction pH electrode as well as a rugged conductivity probe that will withstand even the most aggressive environments. The 12 VDC adapter makes these instruments ideal for all continuous monitoring applications.

Please note: This item cannot work with a digital ballast.

Features

  • Large, dual-level backlit LCD
  • Waterproof
  • Auto calibration & pH temp. computing
  • Adjustable TDS ratio and adjustable β
  • Stability indicator and HOLD
