The 6-in-1 PHH-126 meter was designed 
with a built-in rechargeable battery. The 
built-in battery can last approximately  
3 years, with standard charging time of 
approximately 2 hours. The PHH-126 can 
measure 4 parameters including pH (probe 
sold separately), temperature, conductivity 
and TDS. This multi-parameter water 
quality monitor is a versatile instrument 
with reliable multi-probe system which is 
easy-to-use and easy-to-read. It features 
simultaneous measurements of pH probe 
(sold separately), temperature (°C or °F), 
conductivity (EC or CF) or TDS with a 
single push of a button. The PHH-126 is 
economical and designed for both nontechnical and technical personnel to use.
