The Lumin-S optical dissolved oxygen sensor delivers reliable DO measurements over a long operating life. There are no membranes to replace, no electrolyte solutions to replenish, and no anodes to clean. Maintaining the sensor is as easy as replacing the optical sensing cap once every 1-2 years,…

The ORP2000 features double junction reference protection, which prevents contamination, by sample components that interact with silver (Ag). The durable Ultem® body ensures extensive chemical compatibility.

Our DO6400 series of galvanic dissolved oxygen sensors deliver accurate measurements with very fast response time. Calibration is simple and only requires a single-point air calibration. Sensor directly outputs Millivolt, 4-20mA analog or MODBUS/RS485 digital signal scaled to the sensor range for…

The ORP3000 is durable, research grade ORP electrode. Ideal for difficult sample types: Double junction reference protection for testing samples containing heavy metals, TRIS buffer, and other contaminants.

The ORP1000 is a durable and easy to use ORP sensor and has built in protection for the ORP sensor surface. Use with any ORP meter accepting a BNC connector.
