WTW MultiLine Field pH Meters

pH Meters Are Built to Withstand the Toughest Field Conditions

The WTW MultiLine Field pH Meters have set standards for accuracy, versatility and reliability. Built to withstand the toughest field conditions, each meter combines the latest in durable sensor technology with a shock-resistant ABS case that is guaranteed dustproof, and submersible.
The Multi pH / Oxi 340i pH Meter (No. 222450) allows simultaneous monitoring of pH or ORP, dissolved oxygen and temperature. Multi pH / Conductivity 340i pH Meter (No. 222451) gives simultaneous monitoring of pH or ORP, conductivity/salinity and temperature. Both pH Meters come with one SenTix 41 pH / temperature combination electrode with 3m cable (separate ORP probe required for measuring ORP), professional hardcase, RS-232 interface, calibration and maintenance solutions (including membrane caps for dissolved oxygen sensor), sensor stands and beaker. The pH / Oxi Meter includes a CellOx® 325 oxygen sensor with 3m cable, temperature sensor and waterproof plug. The pH / Conductivity Meter includes one TetraCon® 325 4-electrode cell with 3m cable, temperature sensor and waterproof plug. Operates up to 2500 hours on four 1.V batteries, included. Meter dimensions: 6.8" x 3.1" x 1.5". Weight: 11.0 oz.
