SD7420CD-ORP Differential ORP Probe with Direct 4-20mA Output

$792.60

When an ORP sensor is constantly measuring a wastewater treatment process, it will be exposed to chemicals, suspended solids, and other contaminants. These contaminants can cause fouling of the ORP sensor reference, leading to sensor failure. Differential ORP sensors utilize three electrodes instead of the conventional two. This special design allows the sensor reference (salt bridge) and buffered electrolyte solution to be replaced, which extends working lifetime. Our SD7420CD features differential sensor technology with a direct 4-20mA output, so it can be integrated into control systems without the use of a transmitter or controller.

True differential measurement technology using solution ground
Virtually zero ground loop measurement error
No transmitter or controller required
Constructed of durable Ryton^® PPS
Two year limited warranty
