Oxidation Reduction (REDOX) Potentiometers,

ORP Meters, Probes & Controllers

 Click Here for Ozone ORP for Aquaculture

and Fish Farming or Aquaria

Oxidation Reduction (Redox) Potential
ORP, or Redox, is a measurement of water's ability to oxidize contaminants.
The higher the ORP the greater the number of oxidizing agents.

Measure Anti-Oxidants
Checking ORP is a simple way of monitoring the effectiveness of a sanitizer or the quantity of anti-oxidants in a liquid.

There are numerous applications for ORP, each with it's own specific optimum value.
The minimum ORP for pool & spa disinfection (set by the WHO) is 650mV.

Handheld ORP Meter
Priced @ R 3 348.00 excl VAT
Tester for ORP Measurements

Oxidation is a process in which a molecule or ion loses electrons.
This occurs most readily in water treatment as well as pool and spa maintenance where an oxidizer, such as chlorine or ozone, is added to the water to destroy contaminants.
The higher the ORP value, the greater the sanitizing power of your water. The ORP tester can provide a valuable indication of water quality.
HI 98201 is a unique hand-held tester developed for quick and affordable
tests. The ORP tester utilizes a platinum electrode and unique cloth fibre junction, which can be pulled out when clogging occurs, reactivating the reference and restoring the electrode.

Product Features

NIST or USA pH BUFFER OPTIONS
alpha pH 550 Monitor and 560 Controller allow user to select USA (4.01, 7.00 or 10.01) or NIST (4.01, 6.86 or 9.18) pH buffer standards during calibration.

CUSTOM DUAL DISPLAY LCD
Primary and secondary displays are available for simultaneous display of pH, ORP, Conductivity and Temperature values. Allows instantaneous viewing of measured readings and setup configurations.

EASY PUSH-BUTTON OPERATION
Simply calibrate or adjust setup configuration with just a few touches of the buttons. Intelligent program in alpha pH 550 Monitor and 560 Controller prompts respective buffers for easy calibration. Similarly, push-button offset adjustment makes calibration simple in the conductivity models.

TEMPERATURE COMPENSATION
Compensates variance in the measured readings due to temperature fluctuations, either Automatically (with Pt 100) or Manually (Process and Calibration temperatures can be set separately).

PANEL OR WALL MOUNT, IP65 WEATHERPROOF HOUSING
Meters can be mounted on the wall or in a control panel. In addition, the IP65 rated housing allows the meter to be installed outdoors or indoors. Mounting accessories are included for both types of mounting.

SYMMETRICAL MODE OF OPERATION
Unique mode available in the alpha pH 550 Monitor and 560 Controller allow the meters to be operated in environments with electrical interferences. Simply configure the meter to the symmetrical mode and attach a potential matching pin.

EASY TO USE CONTROLLER FUNCTIONS
Two switching contacts acting as set-point relays simplify your task of controlling various processes. Separately adjustable high and low set-point hysteresis ensure chatter-free signal at the set-points.

ADVANCED FEATURES FOR BETTER CONTROL
Ability to set a time-delay up to 2000 seconds eliminates unneeded control and prevents false alarms, making it ideal for industrial environments.

BACK-LIT UV LIGHT PROTECTED LCD
Back-lit display ensures easy reading even in the dark. UV light protection minimises adverse effect of exposure to sunlight.
