Sensors:

The Q46R ORP Monitoring System uses the Q22R sensor with a few different options as listed & described below. Select the best option for your set up and application.

ORP sensor is a 1" NPT, dual-electrode design. The electrode is fully sealed in a glass to prevent contamination of the sensor. The housing or chamber of the sensor is fully serviceable by removal of the saltbridge and replacement of the sensor solution (Part Numbers 09-0042 for 200mV or 09-0043 for 600 mV – both are 500mL bottles).

PEEK with cord Sensor

The sensor is constructed of molded PEEK (poly-ether-ether-ketone) components. These components include the saltbridge, body, all rear seal components, and all internal components. The unique body is hex shaped to facilitate quick connection to standard 1" NPT fittings, and includes a titanium ground electrode to improve signal stability and enable electrode breakage diagnostic functions to be performed. The sensor features a Pt1000 RTD for high accuracy temperature measurements, and an integral preamplifier to provide a low impedance signal output capable of being driven 3000 feet with standard sensor cabling.

The sensor preamplifier contains features to monitor for electrode breakage and sensor seal failure and are encapsulated into the sensor. The sensor is highly chemical resistant, cross-linked polyethylene jacketed cable that contain two foil shields for optimum electrical performance.

The sensor saltbridge shall be a high capacity, dual-junction, high capacity device. The saltbridge shall be completely replaceable.

Insertion Sensor

The sensor is constructed of molded PEEK (poly-ether-ether-ketone) components, but the sensor can be inserted. This is made from 316SS.

 

Sanitary 1 1/2" Sensor

The sensor is constructed of molded PEEK (poly-ether-ether-ketone) components, but the sensor comes with a pre-installed 1 1/2" sanitary connection. This is made from 316SS.

 

Sanitary 2" Sensor

The sensor is constructed of molded PEEK (poly-ether-ether-ketone) components, but the sensor comes with a pre-installed 2" sanitary connection. This is made from 316SS.

 

PEEK with electrical connector Sensor

The sensor is constructed of molded PEEK (poly-ether-ether-ketone) components, but the sensor comes with electrical connector. The unique body is hex shaped to facilitate quick connection to standard 1" NPT fittings, and includes a titanium ground electrode to improve signal stability and enable electrode breakage diagnostic functions to be performed.

 

 

 

Sensor Cable Lengths:

The sensor comes with a standard 15 foot length cable. We offer the option of 30 feet or 60 feet, but custom lengths are available upon request.

Q45R Features:

-Loop or Battery-Operated Power Options

-Differential Sensors for long operating life

-Submersion, In-Line, or Sanitary-Style Sensors

-Clear Display -Large, easy-to-read LCD display.

-Special High Purity sensor option

-Flexible Mounting - NEMA 4X (IP-66) enclosure is suitable for wall or pipe mounting.

ORP Calibration:

The Q22 ORP sensor used on the Q45R ORP Transmitter can be calibrated and rebuilt for long-term use.  The ORP sensor is calibrated to a buffer solution, listed below, choose the buffer solution relevant to your ORP readings and desired calibration point.  Each buffer solution product page provides detailed instructions on how to calibrate the ORP sensor.

Measure Ozone in water with ORP Meters:

How does an ORP Meter work?

ORP stands for oxidation-reduction potential. It is a measure of the ability of a solution to oxidize or reduce other substances. ORP may also be referred to as redox Potential.

ORP levels in water can be measured with an electronic ORP meter. ORP meters use electrodes in water that measure the voltage difference between the two electrodes. Water with a higher potential to lose electrons (oxidize) will create a higher ORP reading, measured in Millivolts (mv). Lower, (potentially negative) ORP values indicate the water is more reducing.

Using ORP to Measure Dissolved Ozone

ORP meters can indicate dissolved ozone levels in water. Ozone, being a strong oxidizer, increases water's ORP. However, other factors like pH, dissolved oxygen, and other substances can also affect ORP, meaning there's no direct correlation between ORP values and ozone levels.

For specific applications, ORP meters can be calibrated or correlated to known ozone levels, provided other water parameters remain stable. This makes ORP valuable for monitoring changes in dissolved ozone and general water quality.

These tools can be used to measure ozone in water for correlation purposes:
