Know your chloride level—not just your salt level.
Measure chloride ion in water without a heated digestion step. This matched high-range reagent kit supports 80–1000 mg/L as Cl⁻ on the documented HI83314 and HI83399 methods, helping you choose chloride chemistry rather than a chlorine or salinity test.

Choose the right analyte and range
Choose this kit for chloride ion (Cl⁻), not free or total chlorine (Cl₂), and not sodium-chloride salinity. The documented range is 80–1000 mg/L as Cl⁻. For expected levels below 100 mg/L, the manuals recommend the lower-range method for improved precision; this page sells only the HR kit.
A short, nonheated workflow
Add 0.1 mL of sample to the sample vial. Slowly add 3 mL of HI96793-0 Chloride Reagent to each sample vial and to the separate blank vial, following the manual’s mixing instructions. Allow 3 minutes for color development, zero with the blank, then read the sample. No external heated digestion or reactor is specified.
What is included—and the real sample capacity
Supplied as the HI96794-25 high-range kit: 25 HI96794V-0 reagent vials and HI96793-0 Chloride Reagent bottle. HI96793-0 is the legitimate liquid component of this HR kit, not an alias for the HI96793-25 low-range kit. Total bottle fill volume is not stated here; the 3 mL dose is not a bottle-volume specification. One pack contains 25 reagent vials. The current instrument manuals specify reagents for 24 sample tests: a separate reagent blank consumes one vial. Up to 24 sample tests assumes one blank reused within the permitted window; fresh blanks, quality-control checks and repeats consume additional capacity. This is not a promise of 25 independent sample tests.
Plan batches around the reagent blank
Reagent blank correction is required. The current manuals allow one blank to be reused for up to one day at room temperature in dark storage, or up to three days refrigerated. Bring a refrigerated blank to room temperature before measurement, and use the same reagent lot for blank and samples. This is a blank-use window, not an extension or guarantee of reagent expiry.
What you need separately
Use a compatible HI83314 or HI83399 photometer, the model-appropriate adapter specified by its current manual, accurate tools for 0.1 mL and 3 mL dosing, clean vial exteriors and suitable PPE. Instruments, adapters and dosing tools are not included. Select the Chloride HR method and follow the manual’s adapter instructions; no physical vial-diameter claim is made here.
Prepare the sample for a useful result
Analyze promptly after collection. The manuals specify sample temperature 20–25 °C and initial sample pH 3–10, with pH below 2 after reagent addition. Filter turbid samples and adequately treat intense color. Bromide and iodide can give high-biased results; consult the full interference limits before interpreting a result. Store unused vials in their packaging at 15–25 °C and follow actual lot instructions and expiry.
Safe handling and shipping review
These are hazardous laboratory reagents, including mercury-thiocyanate vial chemistry and an acidic liquid component. Read both exact-component US SDS before use and arrange appropriate waste handling. Component SDS contain transport classifications; they are not a complete-kit shipping determination. Confirm destination, packaging and carrier requirements before ordering. No air eligibility or blanket ground-only guarantee is made for this offer.
Frequently Asked Questions
Does this measure chlorine or salinity?
Choose this kit for chloride ion (Cl⁻), not free or total chlorine (Cl₂), and not sodium-chloride salinity. The documented range is 80–1000 mg/L as Cl⁻. For expected levels below 100 mg/L, the manuals recommend the lower-range method for improved precision; this page sells only the HR kit.
How many sample tests can I obtain?
One pack contains 25 reagent vials. The current instrument manuals specify reagents for 24 sample tests: a separate reagent blank consumes one vial. Up to 24 sample tests assumes one blank reused within the permitted window; fresh blanks, quality-control checks and repeats consume additional capacity. This is not a promise of 25 independent sample tests.
Why does the bottle say HI96793-0?
Supplied as the HI96794-25 high-range kit: 25 HI96794V-0 reagent vials and HI96793-0 Chloride Reagent bottle. HI96793-0 is the legitimate liquid component of this HR kit, not an alias for the HI96793-25 low-range kit. Total bottle fill volume is not stated here; the 3 mL dose is not a bottle-volume specification.
Which benchtop photometers support this kit?
Use a compatible HI83314 or HI83399 photometer, the model-appropriate adapter specified by its current manual, accurate tools for 0.1 mL and 3 mL dosing, clean vial exteriors and suitable PPE. Instruments, adapters and dosing tools are not included. Select the Chloride HR method and follow the manual’s adapter instructions; no physical vial-diameter claim is made here.
Does the procedure need a digestion heater?
Add 0.1 mL of sample to the sample vial. Slowly add 3 mL of HI96793-0 Chloride Reagent to each sample vial and to the separate blank vial, following the manual’s mixing instructions. Allow 3 minutes for color development, zero with the blank, then read the sample. No external heated digestion or reactor is specified.
How long can I reuse the blank?
Reagent blank correction is required. The current manuals allow one blank to be reused for up to one day at room temperature in dark storage, or up to three days refrigerated. Bring a refrigerated blank to room temperature before measurement, and use the same reagent lot for blank and samples. This is a blank-use window, not an extension or guarantee of reagent expiry.
What sample conditions can affect results?
Analyze promptly after collection. The manuals specify sample temperature 20–25 °C and initial sample pH 3–10, with pH below 2 after reagent addition. Filter turbid samples and adequately treat intense color. Bromide and iodide can give high-biased results; consult the full interference limits before interpreting a result. Store unused vials in their packaging at 15–25 °C and follow actual lot instructions and expiry.
What safety documents and shipping checks are needed?
These are hazardous laboratory reagents, including mercury-thiocyanate vial chemistry and an acidic liquid component. Read both exact-component US SDS before use and arrange appropriate waste handling. Component SDS contain transport classifications; they are not a complete-kit shipping determination. Confirm destination, packaging and carrier requirements before ordering. No air eligibility or blanket ground-only guarantee is made for this offer.
