Description
OMEGA ® Basic Portable pH Meters, the PHH-905, PHH-910 and PHH-915 Series, provide affordable, convenient means for making basic pH and mV measurements.These OMEGA ® portable pH meters are easy to operate. They were specifically designed to meet the challenges of outdoor or production plant use. The sealed, waterproof case is buoyant and fully immersible in water up to 1 meter in depth. The ergonomic design provides comfortable operation in either hand with soft rubber surfaces for firm grip. No matter where you need to take measurements, these meters are ready to go along. Four AA batteries supply energy for up to 4000 readings (approximately 240 hours of use). Operating the PHH-905, PHH-910 and PHH-915 Series couldn’t be easier. Just press “Standardize” and the meter automatically recognizes 22 different buffers, enters the appropriate buffer, and checks electrode quality. Additional operations are just as easy using the meter’s function keys. Basic Portable Meters make it easy to obtain good results by providing up to three calibration points (buffers), clear prompts and error messages. The high contrast LCD display is easy to read with large 12.7 mm ( 1 /2 ") characters. The PHH-915 has dual electrode standardization which lets you switch between a standard glass electrode and solid-state FET (field effect transistor) pH electrode without restandardizing. Auto-off mode allows you to program the meter to automatically shut off after six minutes of non-use to save battery life, or to run continuously to monitor samples for longer periods. External power and serial interface options provide additional operating flexibility by allowing you to run the meter from an ac power source and to interface with a printer or computer.
