WTW Portable pH Meters - Measures pH, mV, ORP, Temperature

Portable and convenient, these hand-held pH meters are designed for use in the field, laboratory or plant. Meters have shock-resistant housing and are waterproof. The standard model features simultaneous display of pH or mV and temperature, automatic buffer recognition, 3-point calibration, an electrode performance indicator to ensure optimal electrode performance and an auto-read function for stable measurements. All meters have an integrated power consumption feature that allows 3000 hours of continuous use. Models 3210 & 3310 offer 800-point data storage, a calibration alarm and are GLP conforming. Meter kits include pH buffers (pH 4 & 7) and 3M KCl solution. When pH electrodes are included, they are epoxy body and gel filled with a DIN connector. Bi-directional RS232 interface on Model 3310. Warranty is 3 years. Power: 4 AA batteries. With an optional AC adapter, Model 3310 can operate on 120 volt. CUL Approved.
