Hanna Instruments ' Checktemps 1 is a precision thermometer with remote probe and silicone cable, accuracy ±0.2°C, waterproof IP 65, EN 13485 compliant.
This universal temperature tester has been specially designed for remote temperature measurements while maintaining a comfortable reading. The HI98509 Checktemp 1 comes complete with stand and batteries.
This is a function that ensures that no electronic fault will falsify the measurements.
This system automatically runs a diagnostic during start-up and displays a status report on the screen (0 for Ok and Err if a malfunction is observed).
Liquid reagent for seawater alkalinity (HI 755), 25 tests.
Thermometer to stick on the windows of the aquarium. Temperature range of 18 to 34 degrees
High sensitivity test kit for magnesium (Mg) levels in seawater. Laboratory precision at an attractive price for your tests!
High sensitivity test kit for calcium (Ca) levels in seawater. Laboratory precision at an attractive price for your tests.
Checker HC mini-photometer for measuring alkalinity in seawater up to 300 mg/L (ppm).
HI 755 is delivered with 2 measuring cuvettes and their caps, 1 bottle of liquid reagent for alkalinity and the battery.
Accurately tests the nitrate level of your seawater.
Allows you to take around 60 measurements.
Instructions in French
Universal 4 to 6 mm aragonite substrate for calcium reactors. It consists of pure aragonite, calcareous algae, small shells, foraminifera, coral fragments and other calcareous marine organisms. With a rich concentration of calcium, carbonate, magnesium, strontium, potassium and other essential trace elements, it's the ideal substrate for calcium reactors needed for the growth of fish, soft and hard corals, crustaceans and all other aquatic organisms. Reduces CO2 consumption.
Test kit, high sensitivity, carbon hardness (kh) in seawater. Laboratory precision at an attractive price for your tests.

Salimeter from Aqua Medic is used for the simple determination of the salt concentration in saltwater aquariums . In saltwater aquariums the specific gravity should be between 1.022 and 1.025.
The Aquarium Systems hydrometer allows you to accurately measure the density of seawater at a lower cost.
The seawater refractometer offers exceptional accuracy because it uses a specific algorithm developed to measure the absolute salinity of seawater at a temperature of 25°C.
Checker HC mini-photometer for measuring phosphates up to 2.50 mg/L (ppm) .
This mini-photometer is compatible for measurements in fresh water and sea water .
HI 713 is supplied with 2 measuring cuvettes and their caps, 6 sachets of powdered reagent and the battery.
