## Description

desertcart.com: Hanna Instruments HI701 Checker HC Handheld Colorimeter for Free Chlorine : Industrial & Scientific

Review: More flexible than it appears - Some instruments are purposely limited to encourage additional purchases. I believe this is one of those instruments. It appears there are several wavelengths and times for different measurements. The wavelengths are determined by the LED color while a resistor in the base of the unit apparently determines the countdown time. In summary, it means a single unit can be used to measure multiple parameters as long as the reagents and reaction times are correct. With two cuvettes, the free chlorine checker can be used for both free and total chlorine as well as other 525nm based tests. I tried this with free chlorine and total chlorine tests and think it is an excellent alternative to Taylor test kits. The Taylor kits (K2005 in particular) require matching light shades of pink to determine chlorine levels. Even holding up to light is not always conclusive and the measurement tolerance is roughly ±0.5 PPM. This meter yields an easy to read number. All the difficulties of pouring the reagent and setting the timer are eliminated if the user simply takes two samples, uses one as the control, and then manually times the wait period (1 minute for free chlorine, 2.5 minutes for total chlorine). Just before the time is completed, put in the unreacted sample, let the unit take the baseline measurement, and then insert the reacted sample and let the checker do its magic. I compared the results to the Taylor test kit and obtained relatively similar readings. The Taylor test kit I have is quite old and the reagents are well past expired (thus the reason for buying this checker). I also used this checker with the Taylor reagents and also obtained relatively similar readings. I purchased 100 test packs for both free and total chlorine so I am set for a while. Note that the Hanna reagents require pH less than 8.2. My pH was high and I did not get useable readings until I lowered the pH to below 8.0. This tester may also be used with other 525nm tests. I have a saltwater aquarium and wanted to check the phosphate/phosphorus levels. The HI 736-25 phosphorus reagents) measured 0.70 PPM. I don't have any algae problems so this seems reasonable. I recently ordered the HI 713-25 phosphate reagents and will compare the readings. I also have some HI 721-25 iron reagents but have not tested with it yet. If anything, I might recommend the Hanna Instruments HI 711 Total Chlorine checker for its 3.50 PPM range. The HI 701 is limited to 2.50 PPM. Both have 0.01 PPM resolution and ±0.03 PPM accuracy.

## Questions & Answers

**Q: Does the HI701 come with reagent?**
A: Yes, but not very many pillows.  The pillows are also over sized and less convenient to use then Hach.  The Hach reagent works with this unit just make sure it's the 10ml pillows.

**Q: How many ppm of free chlorine will this read up too**
A: Range 0.00ppm - 2.50 PPM

Thank you:)

**Q: Do you have to calibrate it before every single use or does one calibaration lasts a while ?**
A: You can buy a calibration kit for this. It's cheap. It has a clear vial and a pink vial that should read 1.00 and I check it every few months to make sure its still close. Same steps as a normal residual check
 The steps for every time you check the chlorine residual include a 'calibration' to the clear water before adding the packet.
Step one turn it on, shows C-1
Step two fill the vial with water and put it in and press the button
Step three, after it says C-2, take the vial out and add the packet.
Step four put it back it after a shake and press the button. Done.

**Q: The product data pdf provided in this listing states the Hanna analysis devices are manufactuered in their new state of art  European plant.  Correct?**
A: Yes
