Labchem-ph Benchtop Ph - Mv - Temperature Meter


At last - a pH meter that has all the features required for precision laboratory work, but which is easy enough for anybody to use. 

The 16 character alphanumeric display has huge 14.5mm digits. It features simultaneous readout of pH/mV and temperature and user-friendly full-text messages.

The new Automatic Stability Function (ASF) makes taking readings absolutely simple. When all the readings have fully stabilised, the ASF system will freeze the display and show a tick. The reading can then be recorded as required. The user can also disable the ASF system.

The labCHEM-pH is ideal for Quality Control laboratories, plant operators, educational use and many other purposes. It has been designed primarily for ease of use. Operators with little or no laboratory experience can operate the labCHEM-pH with complete confidence quickly and easily.

The labCHEM-pH is fully waterproof to IP65, so it is suitable for even the harshest laboratory or factory environments. It has just four keys to make operation of the labCHEM-pH absolutely simple.

Calibration of the labCHEM-pH is fully automatic at the press of just one key. The meter automatically recognises buffers and calibrates itself accordingly. The electrode asymmetry and slope are displayed at calibration, allowing for preventative maintenance and instant troubleshooting.

Expand the capabilities of the labCHEM-pH with the optional RS232 interface. All readings obtained with the labCHEM-pH can be stored permanently on disk. The WinTPS software package is also available, allowing the labCHEM-CP to communicate with a PC running Windows 95, 98, ME, 2000 & XP.

An analogue recorder output is another option. This provides an interface with pen type recorders or dataloggers with analogue input. A polarisation output makes it possible to use the labCHEM-pH for moisture measurements using the Karl Fischer titration method.

The labCHEM-pH operates from an AC/DC power adaptor. Adaptors are available for all countries.
The labCHEM-pH is proudly designed and manufactured in Australia. Our aim is to provide you with the best quality, service and value for money. The TPS Quality System has been certified in accordance with the AS/NZS ISO 9001 standard. Since 1968, TPS has built a reputation for excellent backup service that is second to none.
