Hanna Instruments Checker Marine Alkalinity Colorimeter Information


Product Manuals & Documentation



The HANNA Alkalinity Checker bridges the gap between simple chemical test kits and professional instrumentation. Chemical test kits are not very accurate and have low resolution while professional instrumentation can cost hundreds of dollars and can be time consuming to calibrate and maintain. The HANNA Alkalinity Checker is accurate and affordable.

The HANNA Alkalinity Checker features an accuracy of ±5 ppm (mg/L) ±5% of reading and uses the colorimetric method.

The contoured style of this Alkalinity Checker fits in your palm and pocket perfectly and the large LCD is easy to read. The auto shut-off feature assures the battery life will not be drained if you forget to turn it off.

The HANNA Alkalinity Checker is extremely simple to use. After zeroing the instrument with your water sample, add the reagent to the cuvette and gently invert 5 times. Then insert the cuvette into the HANNA Alkalinity Checker and press the button to read the results. It`s that easy.

Specifications:
  • Range: 0 to 250ppm (mg/L)
  • Resolution: 0.1 ppm (mg/L)
  • Accuracy: +/- 10% of Reading (0-75) and +/- 5% of reading (75-250)
  • Battery Type: 1 - 1.5V AAA

HI755 Checker HC is supplied with 2 sample cuvettes with caps, liquid reagent and 1 1.5V AAA battery and instructions.

The Hanna Alkalinity Checker measures in ppm. In order to convert to DKH: ppm / 50 x 2.8 = KH

Eliminates guesswork

4.0 5
Experience Level: Expert


Comments: This is especially great if you have multiple people doing testing of your system as everyone seems to read colors or color changes slightly different. The only concern I have is that, doing side-by-side tests, the reading I get on the Hanna checker is considerably different (lower) than that of the Salifert test kit we have been using. At this point, I can't say which is more accurate but it disturbed me that there is such a difference.

4.5 5
Experience Level: Beginner


Comments: i can't really say its accurate cause i don't have anything to base it on. but i would say it is simple to use and no more figuring out the color. although i don't like that ppm is used as supposed to dKH but i guess they have a reason for that. i can always convert it.

Comments: My wife has a complete set of test kits that use little charts to identify a general range of measurement. They are ok, and get the job done, but I absolutely prefer the precision and accuracy of the Hanna products to the test kits that test a range. It's like comparing the difference between using a hand saw and a precision table saw. I have the Hanna test kit for alkalinity, phosphate and calcium. I only wish that the nitrate checker were more affordable.
