ORP Meter Rentals

Our ORP meters are useful in either the field or the lab for quick and easy ORP measurements. We carry models with optional 100 foot extension cables or RS232 outputs for direct connection to a printer or PC.

Thermo Scientific Orion 250A

ORP/Temp Meter

Thermo Scientific Orion 250A
Magnify

Although useful in the field, the Orion 250A is excellent for labratory measurements due to its RS232 serial port with the ability to directly connect to a printer or pc for data reporting and logging. The serial port can even be used to control the instrument remotely. The 250A can store readings with the push of a button and simultaneously displays both ORP and temperature. Like all of our ORP rentals, it comes calibrated and ready for use.
