Applications:
Essential for harsh industrial environments, water treatment plants, wastewater oxidation control, swimming pool and spa sanitization verification, food and beverage production (sanitizer effectiveness), chemical manufacturing, pharmaceutical production, pulp and paper processing, mining operations, and any application requiring extreme durability and extended cable reach. The epoxy body makes this probe perfect for environments where glass probes would be damaged or broken.
Compatible Meters:
Works with any Milwaukee ORP/mV meter featuring a BNC connector, including portable, bench, and wall-mounted models. The universal BNC connection ensures broad compatibility across the Milwaukee meter lineup and other BNC-compatible instruments.
Understanding ORP Measurement:
ORP (Oxidation-Reduction Potential), also called redox potential, measures the ability of a solution to oxidize or reduce substances. Positive ORP values indicate oxidizing conditions (common in chlorinated water), while negative values indicate reducing conditions. ORP measurement is critical for monitoring water treatment effectiveness, sanitizer levels, and chemical process control.
Why Choose Epoxy Body?
Epoxy resin construction provides unmatched durability in industrial settings where probes are subject to impacts, drops, vibration, and harsh chemical exposure. Unlike glass-body probes that can shatter, the epoxy body withstands extreme abuse while maintaining measurement accuracy and reliability—making it ideal for industrial water treatment, food processing, and harsh manufacturing environments.
Maintenance & Care:
The gel-filled reference system requires minimal maintenance. Keep the platinum sensing element clean and free from deposits. Store with the protective cap in place. Regular calibration with ORP standard solutions ensures optimal accuracy.
Note: Meters sold separately. Regular calibration with ORP standard solutions (e.g., 200 mV, 470 mV) recommended for optimal accuracy.
