WTW VARIO pH Meter

VARIO pH Tester

Compatible with most electrode type, One-hand operation, Twistable display

You notice it immediately: apart from its ergonomic form the new VARIO has no keys, but has an innovative touch screen instead. In this way all functions can be called up and set - a simple touch is enough.

Measuring in no time at all

Just a fingertip touch on the display - and VARIO is ready for use. Immersion in the solution starts the measurement automatically. The stable measurement can be read off from the large display together with the temperature and can also be " frozen" . The memory has space for up to 50 measured values for later evaluation.

If the VARIO is not being used for pH measurements then it can be used as a laboratory clock or timer.

Light, handy, robust - it finds a palce in every laboratory coat without dripping or leaving nasty stains, as it can be stored without KCI.

The VARIO can operate continuously for 1500 hours on one easily replaceable AA ( 1.5V) battery. In addition, the VARIO can operate on line power.

VARIO comes standard with an intelligent glass electrode that is protected by a plastic casing. The conical protective cap does not require KCI which prevents the electrode from dripping and protects it from drying out.

The VARIO can do even more

The adapter contained in the VARIO Set makes the instrument compatible with commercially available precision electrodes. In this way the VARIO measures as accurately and reliably as a hanheld instrument.

You can twist and turn as much as you want, the VARIO is an essential aid whenever speed is required in the laboratory or in production
