Adwa AD-11

AD11 and AD12 are the most advanced microprocessor based IP67 Waterproof pH/Temp pocket testers in the market.
Fast, stable and precise, these testers are for users that require the greatest accuracy. Simple user-replaceable pH/Temp probe:
just unscrew the plastic ring on the top of the electrode and replace it with a new one!

2 rows display LCD (reads both pH and temperature measurements) and built-in HOLD function that freezes the display for easy
and accurate recording. Other features such as stability indicator, automatic calibration and automatic temperature
compensation make these waterproof pocket testers a must-have in a variety of industries. The modular design allows to replace
the electrode in a fast and simple way.

AD11 and AD12 are waterproof pH and temperature testers. The housing has been completely sealed against humidity. All pH readings are automatically temperature compensated (ATC), and temperature values

can be displayed in °C or °F units.

The meter can be calibrated at one or two points for pH with auto-buffer recognition and against five memorized buffer values. Measurements are highly accurate with a unique stability indicator right on the LCD. The models are also provided with a low battery symbol which warns the user when the batteries need

to be replaced. The AD11P pH electrode, supplied with the meter, is interchangeable and can be easily replaced by the user.

The encapsulated temperature sensor allows fast and accurate temperature measurement and compensation.

Each meter is supplied complete with:

• AD11P pH electrode

• 4 x 1.5V batteries, button type

• User manual
