Total chlorine is given by the sum of free chlorine plus combined chlorine, where free chlorine combines with nitrogen to produce chloramines. Chloramines is harmful to aquatic life and damages water treatment plants that use membranes for water purification (e.g. reverse osmosis). Chloramines concentration in water depends on pH, temperature, the initial ratio of chlorine and amines, chlorine demand and total time of exposure.

Both forms of chlorine (free and combined) can exist at the same time, though they need to be measured separately. HI 96761 is an auto-diagnostic portable photometer for accurately measuring trace total chlorine for ion-exchange membranes and resins. The advanced optical system employs a specialized tungsten lamp and a narrow band interference filter, assuring accurate readings between 0.000 to 0.500 mg/L.

The Hanna Trace Total Chlorine Waterproof Photometer instrument is equipped with Cal Check® validation function and standards to validate good performance at any time. Taking just a few short steps, the validation procedure is user-friendly and ensures that the meter is properly calibrated wherever you go. Hanna photometers use the exclusive ready-made, NiST traceable standards to verify the performance of the instrument and recalibrate if necessary. Cuvets are constructed from specialized optical glass to ensure the best and most consistent results.

The positive locking system ensures that the cuvet is in the same position every time it is placed into the measuring cell. Our sample cell is designed to fit a cuvet with a wide neck to make it easier to add both sample and reagents. All instruments are factory calibrated and the electronic and optical design minimizes the need for frequent calibration. Ideal for field applications, these meters are splash proof and the lamp and filter units are protected from dust or dirt by a transparent barrier. Display messages aid the user during routine operation.

The auto-off feature will disengage the meter after 10 minutes of non-use in measuring mode or 1 hour while in calibration mode. HI 96761 utilizes an adaptation of the Standard Methods, 20th Edition, 4500-Cl G. The reaction between chlorine and DPD causes a pink tint in the sample.

The Hanna Trace Total Chlorine Waterproof Photometer is supplied with (2) sample cuvets with caps, 9V battery and instruction manual.

The Hanna HI 9146 is a water-resistant, microprocessor-based, auto-calibrating
Dissolved Oxygen meter with ATC. It has been developed for dissolved oxygen and temperature measurement in water and wastewater as well as other applications such as fish farming. Dissolved oxygen is indicated in hundredths of parts per million (ppm=mg/L) or in % of saturation .

The temperature range is indicated in centigrade from 0 to 50°C with 0.1°C resolution.
The ppm and the % saturation are both compensated for changes in solubility of oxygen
in water and for permeability of the membrane as well as the temperature effect.

Salinity compensation in water allows determination of mg/L of dissolved oxygen in
salty waters and the altitude compensation readjusts for the altitude variance.
Four 1.5V AA alkaline batteries provide power and make the instrument completely portable. The Hanna HI 9146 is also designed to be used with a battery recharger or a 12 Vdc power supply. A 12 Vdc input jack is incorporated into the housing.

A microprocessor ensures an accurate and rapid calibration and measurement. The case rugged and water-resistant for maximum protection in the field as well as in the laboratory.

The dissolved oxygen probe has a membrane covering the polarographic sensor elements and a built-in thermistor for temperature measurement and compensation. The thin permeable membrane isolates the sensor elements from the testing solution, but allows oxygen to enter. When a voltage is applied across the sensor, oxygen that passes through the membrane causes a current to flow from which the oxygen concentration is determined.

Product Specification Summary

The Hanna Dissolved Oxygen Meter or Oxycheck is a water-resistant Dissolved Oxygen meter with manual calibration, automatic temperature compensation (ATC), salinity compensation and direct probe.

The Hanna HI 9147 DO Meter with Galvanic Probe, will test arguably the most important parameter of water quality. Most species require a minimumm of 3 ppm DO, but 8-10 ppm is preferable.

The instrument is equipped with an inductive system for battery recharge, with no external contact, to ensure a watertight seal. Dissolved Oxygen is indicated in mg/L (ppm) or in % of saturation.

The temperature can be measured in the range from -5 to 50°C. The Dissolved Oxygen readings are automatically compensated for the temperature effects on the oxygen solubility and membrane permeability. Moreover, the salinity compensation feature allows determination of Dissolved Oxygen even in salty waters.

The meter is housed in a rugged water-resistant case for maximum protection in the field as well as in the laboratory. The D.O. probe is provided with a membrane covering the galvanic sensors and a built-in thermistor for temperature measurement and compensation.

Two models are available:

• HI 9147-04 with HI 76409/4 probe (4 m cable)
• HI 9147-10 with HI 76409/10 probe (10 m cable)

The thin permeable membrane isolates the sensor elements from the testing solution, but allows oxygen to enter.

Oxygen that passes through the membrane causes a current flow, from which the oxygen concentration is determined.

Product Specification Summary

Nitrates are present in nature as a result of the decomposition of organic microorganisms or due to their use as fertilizers. Nitrates reduce to nitrites, which in turn easily combine to form substances dangerous to man.

A maximum level of 45 mg/L is established as a worldwide guideline for nitrate concentration in water. In Europe, the maximum consented level of nitrates in potable water is 50.0 mg/L, while in the USA the EPA has established a guideline for the maximum level of nitrate nitrogen of 10 mg/L (NO-3-N), which corresponds to 45.0 mg/L of nitrates.

The Hanna HI-93728 Nitrate Low Range Meter is extremely easy to use and gives direct readout on the digital display in mg/L(ppm). To obtain a reading simply take a small sample of water in the glass cuvette supplied, add the reagent (not included), and then place the cuvette in the measuring chamber of the instrument.

For the full product specification and accessories required please see the attached instruction manual.

The HI-93728 is supplied complete with cuvets, battery and instructions.

Hanna ORP Meter (Oxygen Reduction Potential)

Oxidation is a process in which a molecule or ion loses electrons. Reduction is a process by which electrons are gained. A measurement of the potential for these processes to occur is called ORP (Oxidation Reduction Potential). Hanna's ORP is a unique hand-held tester developed to determine this value. ORP is a result of the wide demand for an accurate, affordable ORP tester. ORP has now been redesigned to be easier to use with a reinforced ergonomic casing adding a level of durability which is unsurpassed in the field as well as a much larger LCD for increased readability. This instrument is particularly valuable because there are no chemical test kits or litmus paper that can measure this parameter. Until now the only alternative was an expensive ORP electrode used with a special pH meter with mV readings, now there is ORP. The high-tech platinum electrode assures accuracy along with fast response and excellent repeatability. In addition, the exclusive clogging resistant junction insures extended life for this tester, making clogging no longer a concern.
