Economical pH Testers with 
Replaceable Electrode
PHH-7X
$
45
The PHH-7X pH tester provides users with fast, 
accurate readings on a large, easy-to-read liquid 
crystal display. It is supplied with an unbreakable 
epoxy-body pH electrode which screws directly 
into the lightweight, pocket-sized tester. 
Despite its ruggedness and simplicity, the 
PHH-7X provides accurate readings with 
0.01 pH resolution.
Ideal for measurements away from the laboratory, 
the PHH-7X can be used for checking pH samples 
from pipes, tanks or other industrial applications, 
and its 3000 hour battery life makes it practical 
to use in the field for extended periods of time.
