ORP Meters

ORPscan20 Pocket ORP Tester
Waterproof pocket ORP tester, 1 point calibration, BNC connector enables easy connection to various ORP electrodes, accuracy 2 mV.
Features:
• High-accuracy ORP tester with relative and absolute millivolt measurement modes.
• 1 point offset calibration allows adjusting the displayed value to a known standard.
• Auto-read function senses and locks the measurement endpoint.
• Auto-power off effectively conserves battery life.
• Reset function automatically restores all settings to the factory defaults.
Applications:
• Assesses redox conditions in water treatment and environmental monitoring.
• Verifies disinfectant activity in potable water systems.
• Controls oxidation–reduction processes in wastewater treatment.
• Monitors redox reactions in chemical and industrial processes.
• Measures oxidizing-agent activity in pool and aquaculture systems.
