It features built-in PI control for dosing or neutralization and enhanced diagnostics and communication capability for robust process control in harsh industrial environments. Key specifications include pH measurement range of approx -2 to 16 and ORP up to ±1500 mV, input impedance around 10¹³ Ω, 110–120 VAC power supply at 50\/60 Hz (~10 VA), IP65\/NEMA 4X enclosure, and mounting options that include panel, wall, or pipe installations. This is a discontinued legacy EXA analyzer commonly used for continuous online monitoring in wastewater treatment, chemical processing, food and beverage production, and power generation systems.\u003c\/p\u003e\u003c\/div\u003e","brand":"YOKOGAWA","offers":[{"title":"New","offer_id":46241940177130,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-001.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/yokogawa-ph402g-e-1-e-ph-orp-analyzer-transmitter","provider":"GTG Hardware","version":"1.0","type":"link"}
