Checker pH 1 Meter
This electronic digital pH meter offers highly accurate pH measurements in a simple dip meter. Measurements are down to 0.01 units. Manual 2 point calibration, via calibration solutions at pH 4 and 7(sachets included). The Checker supplies you with fast and accurate readings from 0 to 14 pH with a resolution of 0.01 pH. This compact tester features a large easy-to-read LCD and simple to perform 2-point calibration. The pH electrode of the Checker® can be replaced. You only need to unscrew the electrode from the meter body and screw on a new one. The Checker® is fast, accurate, lightweight and with 3000 hours of battery life, you don't have to worry about frequent battery replacement. Testing pH has never been easier!

Checktemp C Meter
A highly accurate meter. Range –50 to +150 C, resolution 0.1 Immersion time only 20 seconds for a truly accurate reading. Self calibration test feature. Batteries & instructions included. Rated for food, water, & soil use. 5” stainless steel probe (not floating) Checktemp C: A highly accurate meter. Range –50 to +150 C, resolution 0.1 Immersion time only 20 seconds for a truly accurate reading. Self calibration test feature. Batteries & instructions included. Rated for food, water, & soil use. 5” stainless steel probe (not floating)

Digital Salt Meter
The SALINTEST can help you monitor the concentration of sodium chloride, assuring high quality in aquaculture. SALINTEST is also ideal for marine fish tanks and aquariums. Instruments for measuring salinity of seawater currently available on the market are cumbersome and difficult to use. HANNA instruments®  has re-engineered this compact salt tester with a more durable, ergonomic casing and a larger LCD. This electronic meter uses a modified distilled water method and can measure salinity from zero to over 3 ounces of salt per gallon. A conversion list of popular levels is included so you can work in your preferred format(oz,mg/L,%). Comes supplied with calibration solution, batteries and instructions.

Hanna 8-Parameter Water Test Meter
The following meters work using ion specific chemical method, in other words like simple test kits, a chemical is added and a colour is formed and the electronic meter reads the results very accurately in mg/l down to 2 decimal places I.E. 0.01mg/l special reagents (chemicals) are required for each parameter.  This Complete Kit C203 is sound value and is in our opinion better value than the individual iron specific Meters if you can afford the initial layout ... This comes complete with the 5 major test reagents: - pH, Ammonia, Nitrite, Nitrate, Dissolved Oxygen Enough reagents to perform 100 tests How they work? There is no need to calibrate as the test procedure does this for you. Fill the test tube with a clear pond water sample, insert into meter, press the “zero” button (this calibrates the pond water sample to the meter as a reference), add the reagent to the same test tube, Insert back into the meter, press the read timer button, this starts a timer count dow

Hanna Ammonia Meter
Simply fill the test tube with pond water, insert the meter and press the "zero" button.  This will calibrate the pond water sample to the meter as a reference, add the reagent to the same test tube, insert back into the meter, press the read timer button, this starts a timer count down, then the meter shows the result on the digital display. That's it! It doesn't get any easier. Ammonia Meter: This is a very popular meter for obvious reasons. Range 0.00 to 3.00 mg/l resolution 0.01 mg/l Battery, instructions 2 test tubes included. Simple to use, results in less than 4 minutes.

Hanna Nitrate Meter
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.

Hanna Nitrite Meter
Nitrites are an intermediate product in the nitrogen cycle and are produced during ammonia oxidation with water, or even originate in industrial waste directly. They must not be present in drinking water. Nitrites can be harmful to aquatic organisms even in low concentrations and for this reason, they are closely monitored in aquaculture facilities. In cooling towers, however, an adequate amount of nitrites is necessary to prevent corrosion. In high concentrations, they can be harmful to environment and to our fish. Nitrite Meter: Range 0.00 to 0.35mg/l resolution 0.01 mg/l Battery, 2 test tubes, instructions, included. Simple to use, results in 6 minutes.

Hanna Reagents
Purchasing Hanna Instruments is the best investment you can make in your application. To capitalize on your investment, our reagents are produced with exacting quality and then factory sealed to ensure precise and accurate measurements, every time. All reagents are listed by product type and then by parameter.

TDS (Total Dissolved Solids) Meter
The TDS testers are reliable, pocket sized instruments that will give you quick and accurate readings of conductivity and TDS. This popular line of Dissolved Solids Testers has been redesigned to offer a host of improvements. The casing has been designed for increased strength, a better fit for holding and a large LCD for easy viewing. The graphite sensors provide better repeatability since they do not oxidize. The casing has been engineered to allow air bubbles to escape.
