Hanna Instruments Checker Total Chlorine Colorimeter Information


Product Manuals & Documentation



The HANNA HI 711 Checker HC bridges the gap between simple chemical test kits and professional instrumentation. Chemical test kits are not very accurate and only give 5 to 10 points resolution while professional instrumentation can cost hundreds of dollars and can be time consuming to calibrate and maintain. The HANNA HI-711 Checker HC is accurate and affordable.

This Checker HC portable handheld colorimeter features a resolution of 0.01 ppm and ±0.03 ppm (mg/L) ±3% of reading accuracy. It also uses an EPA approved DPD method.

The contoured style of the Checker HC 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 HI 711 Checker HC is extremely simple to use. First, zero the instrument with your water sample. Next, add the reagent. Last, place the vial into the Checker HC, press the button and read the results. It’s that easy.

  • Ideal for Aquaculture and Aquarium testing!
  • Easier to use and more accurate than chemical test kits!
  • Large, easy to read digits.
  • Auto shut off.
  • Operated by a single AAA battery
  • Use for quick and accurate on the spot analysis.
  • Single button operation: zero and measure.
HI 711 Checker HC is supplied with sample cuvettes with caps (2), powder reagents for Total Chlorine (6), battery and instructions.

Specifications:
  • Range: 0.00 to 3.50 ppm (mg/L)
  • Resolution: 0.01 ppm (mg/L)
  • Accuracy: +/- 0.03ppm (mg/L) +/- 3% of Reading

Comments: Package arrived on time and was packed well. The Hanna meters are Much easier than the red sea test kit and I would recommend this kit for someone has any issue with determining the color variations. Very accurate and makes the hobby much more enjoyable.

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.

Comments: The only thing I don't like is the packets of reagent its really hard to get the powder out. Long skinny packets would be better. Overall it is easier than the test kits

Comments: These are awesome instruments! I previously used the Red Sea test kit and looking for the correct color is unachevable. The Hanna digital meters are a sure bet, don't waste your time or money using anything else. One thing I will mention is I saw a video on the Hanna Ca checker and the guy said they replaced the "Reagent B" with a liquid vs. the powder. I recieved the powder packs with mine and it is hard to be sure all the powder makes it into the tester. Overall, both of these are a 5star, I also recommend the Hanna ph probe.

Comments: I have used the Hanna Alkaline tester several times and immediately had a LFS do the same test and the Hanna is always off by 3+ dKH. If I get 121 ppm (which converts to 6.78 dKH), the LFS gets 9.5 - 9.7. Very disappointing. The Hanna Phosphate tester is always right on the mark with the LFS tests.
