Supplier: Amalgamated Instrument Co playlist_addCompare

The Intelligent HH4-PH Hand Held Digital pH meter is designed and manufactured to provide a rugged and reliable instrument for industrial and laboratory applications.

Price Guide (Inc GST): POA

The HH4 Digital pH meter is intelligent yet simple to operate. The instrument may be cycled between pH, millivolts and temperature simply by the push of a button. A hold pushbutton allows the display to be held at the current reading for taking notes and logging purposes.

Calibration is simplified by a pushbutton sequence which allows a single point or two points to be entered into the calibration memory.

The non volatile memory stores the previous buffer values making future calibrating even faster. A unique display of the electrode slope allows you to monitor the condition of the pH electrode.

The programmable digital filter improves stability by smoothing out short term interference - often associated with induced cable noise when stirring liquids.

An automatic switch off function has been integrated into the design to switch the instrument off after a programmable preset time period - thus increasing the battery life.
