Oakton (WD-90003-00) LCD Digital Pocket Thermometer
Oakton WD-90003-00 LCD Digital Pocket Thermometer
The Oakton WD-90003-00 delivers laboratory-grade temperature readings in a pocket-sized design built for daily use. With a 5-inch stainless steel stem and ±1°C accuracy, this digital thermometer handles everything from incoming feed water checks to post-membrane temperature verification across a 14°F to 392°F range.
Designed for Water Professionals
Wide Temperature Range
Measures from 14°F to 392°F (-10°C to 200°C), covering everything from cold feed water to sanitization cycles and heated rinse operations.
High Accuracy
±1°C accuracy with 0.1-degree resolution ensures precise monitoring for temperature-dependent processes like membrane performance and chemical dosing.
Durable Construction
5-inch stainless steel stem resists corrosion in water treatment environments. Protective sleeve with pocket clip keeps the probe safe between uses.
Easy-Read LCD Display
Clear digital readout switches between Fahrenheit and Celsius. 1.5V silver oxide battery provides reliable power for routine field measurements.
Where the Oakton WD-90003-00 Fits
Essential for reverse osmosis system operators monitoring feed water temperature for membrane flux calculations, pre-treatment specialists tracking heat exchanger performance, and filtration technicians verifying pasteurization or sanitization temperatures. Use with any Isopure RO system, commercial filtration setup, or water treatment application where temperature affects chemical reaction rates, solubility, or equipment performance. The compact design fits in toolboxes, pockets, and service kits alongside TDS meters and pressure gauges.
Oakton has built test and measurement instruments for water professionals since 1991, and the WD-90003-00 continues that tradition of reliability.
