The Model 4330 Combination
Conductivity / pH Meter
117 volt Model |
The Techne® Model 4330 Meter is a dual measurement Conductivity and pH instrument. The instrument contains an enhanced 240 x 128 graphics LCD display. pH can be displayed to 3 decimal places resolution whilst mV can be displayed in 0.1mV resolution. Independent or combined use of sensors is permitted - there is no electrical interference between sensors. Product operation protocols have been carefully designed to ensure ease of use enabling the most complex determinations to be carried out by unfamiliar users with confidence. Traceability of calibration and sample data is easily maintained and guarantees a high level of confidence. Product performance is continually monitored and resulting messages are clearly displayed. All results and calibrations are date and time stamped. The Model 4330 Conductivity / pH Meter has been designed and manufactured to comply with European CE regulations and the power supply modules meet the specifications of all major European and North American safety standards. |
