Main highlights

Multiple hardness units optional: Digital Leeb hardness tester supports the conversion between seven hardnesses (HL, HB, HV, HS, HRA, HRB, HRC). The built-in smart chip automatically detects the type of impact device and displays the measurement results directly without manual adjustment. The response speed is 0.5 seconds, which shortens the waiting time and improves efficiency.
High-precision measurement: ABS hardness meter measuring range (170-960) HLD, accuracy ±1 HRC, suitable for measuring different metal hardness values. The 320 x 240 TFT colour screen supports adjusting the LED brightness, so you get clear readings even in dark environments. Note: The Leeb hardness tester requires a thickness of the workpiece to be tested of at least 5 mm or more.
Easy to use and widely used: Leeb sclerometer has a 360 degree gravity compensation function. During the test, only three simple steps are required loading, positioning and releasing the measuring knob to complete the measurement from all directions. Supports presetting the upper and lower limits of the hardness value and automatically emits an alarm when the range is exceeded. Widely used in hardness testing of various metal materials.
800 sets of data memory and thermal printer: improved communication interface (USB 1.1), equipped with microcomputer software to allow a quick connection to the PC. 800 groups of large capacity data storage (number of impact 32~1) facilitate data tracking and analysis. The all-in-one printer can instantly print any number of test reports (including previously saved data).
1800 mA lithium battery: Leeb hardness tester with built-in 3.7 V lithium battery, the maximum capacity can reach 1800 mA, the continuous working time is not less than 160 hours (full charge in 4 hours), and it has power-saving functions such as automatic sleep mode and automatic shutdown. It has a long service life and is environmentally friendly, so you don't have to worry.

Many applications: check the water for your devices, such as osmosis system, softening system, activated carbon filter, espresso machine, washing machine, dishwasher and many more. In addition, you can check the water hardness, such as aquariums, ponds or pools.
Included in the set: 1 x titration solution with 15 ml, 1 x sample tube, 1 x instruction manual (English language not guaranteed), 1 x pipette. With the set you get everything you need for easy and accurate determination of the water hardness. The pipette makes it easier to measure 5 ml of the liquid to be tested.
Easy to use: add 5 ml of test liquid to the sample tube. Add drops until colour change red to blue. 1 drop corresponds to 1 German hardness. 1 German hardness corresponds to 17.8 ppm water hardness. If the liquid turns blue immediately, the water hardness is about 0 dH.
Determine water hardness: determine the water hardness easily and reliably with this product. Lots of lime? Simply interpret the water according to German hardness or ppm. This allows you to easily determine whether you have soft, medium or hard water. Alternatively, test the performance of your filter. With this test, you can determine a water hardness between 0-550ppm.
BMUT quality: the product has been manufactured in Germany and is continuously tested for accuracy and quality. If you have any questions about the product, customer service is always at your disposal.

Versatile: suitable for all waters (tap water, well water, drinking water and spring water). For use in the home, kitchen and garden. For determining the water hardness for: fully automatic coffee machines (to program the hardness), softening systems/water softening systems/descaling systems (to check the function and adjust residual hardness), aquarium, pond and pool.
UNBEATABLE PRICE THANKS TO MANY MEASUREMENTS: Our goal is to provide high quality products at a good price. Make the comparison, our water hardness test is the cheapest: 50 measurements at a total hardness of 25 °dH, 400 measurements at a total hardness of 3 °dH.
Precise results thanks to the proven titration process, quick and easy: fill the supplied container with sample water and add the titration liquid drop by drop until a colour change from red to green occurs. 1 drop of titration liquid corresponds to 1° German hardness (dH). For example: colour change from red to green for the 7th Drop = 7° German hardness (°dH). If the water is directly at the 1st drops of green, the water hardness is 0° German hardness (°dH).
Introducing ourselves: AGUALEVE is a medium-sized, family-run specialist company specialising in water treatment and water technology. Your satisfaction is our number one priority. If you have any questions or difficulties, please feel free to contact us at any time. We promise you to find a solution that will make you 100% satisfied.
