The World’s Most

|
|
Advanced Line of Testers
|
|
|
With
these powerful waterproof testers, you can easily measure pH, EC/TDS,
temperature,
|
|
|
and now ORP, anywhere. Attention to
detail is evident in these advanced instruments with
|
|
|
features
such as replaceable electrode technology and stainless steel temperature
probes
|
|
|
for faster, more precise measurements.
The EC/TDS meters have graphite probes for fast
|
|
|
response and contamination
resistance.
|
|
|
At startup, each tester performs a self check then displays
the remaining battery level
|
|
|
assuring
proper working condition. A stability indicator tells you when to take the
reading
|
|
|
and a
hold button freezes the display for easy and accurate recording. All information
is
|
|
|
displayed on
a redesigned LCD that gives you the complete picture at a glance.
