Product Specification Summary

HI-982401 ORP (Redox) Wall Mounted Indicator is a simple to use and operate wall mounted indicator gives continuous digital readout of the ORP (also known as Redox) values being measured. The front cover incorporates a bright Red LED light as the visual alarm. Should the measured value fall below the user selectable ORP value, then the alarm light will flash to alert the operator that the alarm point has been exceeded.

The HI-982401 has been designed to serve as an ORP monitor where time, space and money are all limiting factors. Thanks to the compact size, the meter together with an ORP electrode can be mounted right next to the chemical dispensing container.

Supplied without sensor (please see recommened accessories below), but with the 12volt power adaptor.

Product Specification Summary

The pH Pronto is a waterproof pH meter with a built-in digital LCD.The meter is supplied with a double-junction, plastic body, gel-filled pH electrode with a 2m cable and a BNC connector, which is protected by a waterproof sheath when fitted to the meter.
The electrode has a unique clogging-resistant Teflon diaphragm. One setpoint can be selected in the 3 to 11 pH range as an alarm point. A red LED warns the user in the event the reading falls outside this setpoint by more than ± 0.5 pH.

Calibration can be performed manually at 1 or 2 points using pH buffer 4 and 7 solutions.

With its IP67 and NEMA 4 protection, the meter fits well in outdoor installations and high humidity environmnents.The casing has also been specially designed to give maximum stability and prevent rolling from any surface. In addition,the moulded hook allows the meter to be easily installed on a wall and close to the Aquarium itself. The 12 VDC power supply is ideal for continuous monitoring over extended periods of time. The meter uses a 12 volt power source which can be from a car battery or similar, or from the mains using a 12volt transformer which is included in the price of the instrument.

Some of pH Pronto's outstanding features include:

• Large and easy to read LCD
• External 12 VDC power supply for continuous monitoring
• Clogging-resistant pH electrode with differential input
• Selectable setpoint and LED Alarm
• One or Two point calibration
• IP 67 and NEMA 4 protection enclosure
• Moulded hook for easy and quick wall installation
• Connectors protected with waterproof sheath

Highly Recommended Accessories

A box of 10 sachets. 5 of pH 4.01 buffer solution and 5 of pH 7.01 buffer solution. Each sachet contains 20ml of solution and can be used to calibrate any of our pocket meter range, or any pH meter with a conventional pH electrode.

The Hanna pH & ORP Continuous Indicator HI-981406 features separate displays for continuous readout of both pH and ORP (also known as Redox). The meter uses a 12volt power source from the mains using a 12volt transformer which is included in the price of the instrument. Also supplied with an earthing pin to ensure that readings are correct and not affected by a lack of earth within a plastic or other form of insulated tank environment.

Designed for aplications where both the pH and ORP need to be monitored, it provides an economic solution to the problem of having to buy 2 separate meters to do the same job. In addition, it incorporates 2 red LED alarm lights which illuminate when an alarm point is reached. These alarm points can be set by the operator and serve to alert when there is a problem in the pool water.

The meter will accept any type of pH electrode or ORP electrode fitted with a BNC connector, but we recommend the HI-2114P/2 pH electrode and the HI-3214P/2 ORP electrode in the accessory section below. Both of these electrodes are specially designed for applications and feature a purpose-built fibre salt bridge junction which is particularly resistant to clogging in water.
