Substance Analysis Instrumentation METCOM Combo Meter for pH, Temperature, Conductivity (Nutrient) in Water with Easy Calibration, Digital TDS Tester for Hydroponic System and Indoor Plant Grow, Pack of 1

Monitor 3 parameters in water: Conductivity (TDS) level to ensure plants get a balanced feed, pH up and down, and temperature with lab quality glass probe; Gereral uses include growing tent, swimming pool, drinking water, and aquarium
This hydroponics meter has ATC that provides consistent reading regardless of any fluctuations in temperature; pH probe is double junction; Conductivity scales include EC, PPM, and CF
Combine with Substance Analysis Instrumentation meters and controllers for full indoor garden nutrients monitoring in water and soil; pH probe requires easy two point calibration; Conductivity and temperature probes come factory calibrated and are ready to use
Other features: Auto off function, low battery indicator, units for temperature; KIT INCLUDES: AAA batteries, pH probe storage cap, and calibration solution, probe care kit is sold separately
Made in New Zealand and manufactured by Substance Analysis Instrumentation, the industry leader in hydroponic testing equipment, built for growers; 5-Year Limited Warranty with proof of purchase (6-month warranty for probes)
