Portable pH Meters Product Description
The pH 1970i Portable pH Meters enable you to carry out pH measurements rapidly and reliably. The portable pH meter provides the maximum degree of operating comfort, reliability and measuring certainty for all applications. The accurate and field-friendly portable pH meters feature a shock absorbing housing that is not only waterproof (IP67) but will actually float. Plus, the portable pH meter’s convenient carrying handle doubles as meter stand for bench top use. The 1970i Portable pH Meters display pH/temperature or mV/temperature simultaneously, which makes taking your pH readings easy. The proven MultiCal® calibration procedures and special AutoRead function enables precise measurements support you in your work with the portable pH meter.
With it’s GLP memory functions, real-time clock, 800 data point memory capacity and convenient carrying handle, the pH 1970i portable pH meter is a complete pH measuring system. The portable pH meter’s standard BNC electrode connector provides for quick connection of one of the waterproof SenTix® electrodes listed below, or use your own existing pH probe.
The pH 1970i Portable pH Meters ship complete with NiMH rechargeable batteries, dual-voltage 110/220 VAC adapter, and neck strap. A pH probe is not included with the portable pH meters. Choose from one of the two waterproof pH electrodes listed below or call us if you need a special purpose electrode for your portable pH meter.
