The PHH-925 is no longer available. Please see the PHH224 as a possible substitute or contact our pH engineering department
for other alternatives.
OMEGA ® Series PHH-925 and PHH-950 Advanced Portable pH Meters, offer research-grade accuracy and advanced menu operation in a rugged, waterproof meter. Both models are dual-channel, dual-input meters, allowing two electrodes to be connected and two measurements to be displayed simultaneously. The PHH-925 allows the use of both glass and solid-state FET pH electrodes and ion selective electrodes. It also measures pH, mV, ion and FET pH.
The versatile PHH-950 has the ability to measure pH, ion, conductivity, resistivity, salinity, and total dissolved solids.
Both the PHH-925 and PHH-950 series perform dedicated key operations like standardizing, changing measurement mode and checking electrode quality (including efficiency or slope). These advanced meters automatically recognize the electrode type you use as soon as you plug it in.
Time and date stamping for GLP or ISO documentation are provided through the built-in clock/calendar. User-friendly prompts and error messages tell you precisely what you need to do in orger to obtain accurate measurements. The easy-to- read display is highly visible with 21-character readout and 16-line alphanumeric display of its 12.7 mm (0.5") characters.
These ergonomically advanced portable pH meters are housed in a rugged, waterproof case complete with soft, non-slip rubber grips to fit firmly in the palm of either hand. Operating options allow you to customize for your application:
• Programmable resolution allows you to select up to three decimal places in pH or three significant figures in ion and conductivity modes.
• Multiple slope standardizations permit entry of up to five standards in pH, ion, and conductivity modes.
• Multiple electrode standardizations allow you to store standardizations for two pH electrodes (1 for each input channel), 2 ORP electrodes (relative mV), five different ion-selective electrodes with ion names and units of measurement, solid-state FET pH electrode (PHH-925 only), or conductivity cell (PHH-950 only).
The units extensive datalogging capability stores up to 250 data points - each with result, unit, temperature, date, time and sample number.
Download or print your results via the optional power/interface docking station.
