Advanced Nitrate Ion Sensor is designed to fit the Multi-Parameter Sensor Housing. Notes:1) This is for the SENSOR ONLY and requires use of the Multi-Parameter Sensor Housing. 2) The sensor housing can be connected to either the Portable Multi-Parameter Water Quality Analyzer, or integrated with 3rd party data loggers or remote monitoring systems via built-in RS485 Modbus output. 3) This unit ships direct from the factory. Please allow an additional 5-10 working days for shipment and delivery. .sper-grid { display: grid; grid-template-columns: repeat(auto-fit, minmax(260px, 1fr)); gap: 20px; } .sper-card { border: 1px solid #e5e5e5; border-radius: 8px; padding: 16px; background: #fff; transition: box-shadow 0.2s ease; display: flex; flex-direction: column; } .sper-card:hover { box-shadow: 0 4px 12px rgba(0,0,0,0.08); } .sper-card img { width: 100%; height: auto; margin-bottom: 12px; display: block; } .sper-title { font-size: 16px; font-weight: 600; margin-bottom: 6px; line-height: 1.3; } .sper-desc { font-size: 14px; margin-bottom: 12px; line-height: 1.4; color: #444; } .sper-specs { font-size: 13px; line-height: 1.6; margin-top: auto; } .sper-spec-row { display: grid; grid-template-columns: 120px 1fr; gap: 6px; margin-bottom: 2px; } .sper-spec-label { font-weight: 600; color: #222; } .sper-spec-value { color: #333; } Nitrate Ion Sensor ISE nitrate sensor for nutrient monitoring.
